Definitions

  • the invention relates to a gluing press for lamellar woods according to the preamble of claim 1.
  • glueing presses For pressing lamellar wood into slabs glueing presses are used, which have a horizontal press table with a lateral pressing device and a side stop. The juxtaposed with their long sides, provided with glue woods are pressed against the side stop and pressed it. On the plate to be pressed, a clamping device is placed, with the vertical alignment and tension of the lamellar woods is achieved. Since the plates to be produced often have different widths and thicknesses, the glue presses must be cumbersome and time-consuming to change because a variety of printing elements must be inserted or installed. For certain press widths additional timber is required.
  • An adhesive press according to the preamble of claim 1 is made WO-97/17178-A known.
  • the invention has for its object to form the generic glueing press so that different widths and / or high plates can be easily and inexpensively manufactured.
  • the woods are pushed against the pressing unit with the stop. Since the stop is displaceable in or against the pressing direction, it can be easily and quickly adjusted to different plate widths, without affecting the stability of the stop is affected.
  • the pressing unit itself only needs a small stroke to apply the pressing force to the woods.
  • the pressing force is generated by the fact that a pressure medium is placed under pressure during the pressing process, whereby the necessary for pressing the woods pressing pressure is formed.
  • the gluing press is used for the production of boards and boards from lamellar solid woods. These solid woods are glued and pressed on their adjacent sides.
  • the glueing press has a frame 1 on which a horizontal press table 2 is located. On it are to be pressed wood 3 during the pressing process.
  • the press table 2 has a flat support surface 4, which is bounded on a longitudinal side by juxtaposed pressing elements 5.

  • the stop rulers 6 are in the support surface 4 parallel to each other lying slots 7 are provided which extend from the pressing elements 5 opposite longitudinal side approximately over half the width of the support surface 4. With the stop rulers 6 a very simple adjustment to the respective width of the plate 3 to be produced from the woods is possible.
  • the stop rulers 6 extend overall over the length of the support surface 4, so that they can be fully utilized for pressing the woods 3. Thus, for example, with a possible press width of, for example, 1200 mm plates up to a width of 600 mm can be inserted several times side by side in the glueing press. In this way, the pressing area can be used optimally.
  • the slots 7 advantageously extend over half the width of the support surface 4.
  • the stop rulers 6 are provided detachably on the press table 2. In this way, a simple adjustment of the fence rulers 6 is guaranteed to different thicknesses of wood 3. Depending on the thickness of the wood to be glued together 3 different height fence rulers are used in the press table 2.

In this way, the adjacent pressing elements are aligned with each other. In this case, this positive connection is designed so that adjacent pressing elements 5 can still slightly move against each other.

Auf die zu verpressende Platte wird eine Spanneinrichtung aufgelegt, mit der eine vertikale Ausrichtung und Spannung der lamellenförmigen Hölzer erreicht wird. Da die herzustellenden Platten häufig unterschiedliche Breiten und Dicken haben, müssen die Verleimpressen umständlich und zeitaufwendig umgestellt werden, da eine Vielzahl von Druckelementen eingelegt bzw. eingebaut werden muß. Bei bestimmten Preßbreiten sind zusätzlich Zuleghölzer erforderlich. Die am festen Anschlag anliegenden Hölzer werden auf der Gegenseite durch Preßzylinder mit entsprechenden Druckelementen beaufschlagt, die bei einer Umstellung auf andere Plattenbreiten und/oder Plattendicken einzeln ausgewechselt werden müssen. Da der Spannweg dieser Preßzylinder beschränkt ist, ist auch die mögliche Plattenbreite eingeschränkt.For pressing lamellar wood into slabs glueing presses are used, which have a horizontal press table with a lateral pressing device and a side stop. The juxtaposed with their long sides, provided with glue woods are pressed against the side stop and pressed it. On the plate to be pressed, a clamping device is placed, with the vertical alignment and tension of the lamellar woods is achieved. Since the plates to be produced often have different widths and thicknesses, the glue presses must be cumbersome and time-consuming to change because a variety of printing elements must be inserted or installed. For certain press widths additional timber is required. The adjacent to the fixed stop woods are acted on the opposite side by pressing cylinder with corresponding pressure elements, which must be replaced individually when switching to other plate widths and / or plate thicknesses. Since the clamping path of these press cylinders is limited, the possible plate width is limited.

Eine Verleimpresse gemäß dem Oberbegriff des Anspruchs 1 ist aus WO-97/17178-A bekannt.An adhesive press according to the preamble of claim 1 is made WO-97/17178-A known.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Verleimpresse so auszubilden, daß unterschiedlich breite und/oder hohe Platten einfach und kostengünstig hergestellt werden können.The invention has for its object to form the generic glueing press so that different widths and / or high plates can be easily and inexpensively manufactured.

Diese Aufgabe wird bei der gattungsgemäßen Verleimpresse erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic glueing press according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Verleimpresse werden mit dem Anschlag die Hölzer gegen die Preßeinheit geschoben. Da der Anschlag in bzw. entgegen Preßrichtung verschiebbar ist, kann er einfach und schnell auf unterschiedlichste Plattenbreiten eingestellt werden, ohne daß dadurch die Stabilität des Anschlages beeinträchtigt wird. Die Preßeinheit selbst benötigt nur noch einen geringen Hub, um die Preßkraft auf die Hölzer aufzubringen. Die Preßkraft wird dadurch erzeugt, daß ein Druckmedium beim Preßvorgang unter Druck gesetzt wird, wodurch der zum Verpressen der Hölzer notwendige Preßdruck gebildet wird.In the glueing press according to the invention the woods are pushed against the pressing unit with the stop. Since the stop is displaceable in or against the pressing direction, it can be easily and quickly adjusted to different plate widths, without affecting the stability of the stop is affected. The pressing unit itself only needs a small stroke to apply the pressing force to the woods. The pressing force is generated by the fact that a pressure medium is placed under pressure during the pressing process, whereby the necessary for pressing the woods pressing pressure is formed.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.

Die Verleimpresse dient zur Herstellung von Platten und Kanteln aus lamellenförmigen Massivhölzern. Diese Massivhölzer werden an ihren aneinanderliegenden Seiten beleimt und verpreßt.The gluing press is used for the production of boards and boards from lamellar solid woods. These solid woods are glued and pressed on their adjacent sides.

Die Verleimpresse hat ein Gestell 1, auf dem sich ein horizontaler Pressentisch 2 befindet. Auf ihm liegen die zu verpressenden Hölzer 3 während des Preßvorganges auf. Der Pressentisch 2 hat eine ebene Auflagefläche 4, die an einer Längsseite durch nebeneinander liegende Preßelemente 5 begrenzt ist. An der gegenüberliegenden Längsseite befinden sich beispielhaft zwei fluchtend zueinander liegende Anschlaglineale 6, mit denen die Hölzer 3 quer zur Längsrichtung der Auflagefläche 4 gegen die Preßelemente 5 verschoben werden. Je nach Größe des Pressentisches 2 können auch nur ein oder weitere Anschlaglineale vorgesehen sein. Sie werden in noch zu beschreibender Weise quer zur Längsrichtung der Auflagefläche 4 verschoben. Zur Führung der Anschlaglineale 6 sind in der Auflagefläche 4 parallel zueinander liegende Schlitze 7 vorgesehen, die sich von der den Preßelementen 5 gegenüberliegenden Längsseite etwa über die halbe Breite der Auflagefläche 4 erstrecken. Mit den Anschlaglinealen 6 ist eine sehr einfache Einstellung auf die jeweilige Breite der aus den Hölzern 3 herzustellenden Platte möglich. Die Anschlaglineale 6 erstrecken sich insgesamt über die Länge der Auflagefläche 4, so daß sie vollständig zum Pressen der Hölzer 3 ausgenutzt werden kann. So können beispielsweise bei einer möglichen Preßbreite von zum Beispiel 1.200 mm Platten bis zu einer Breite von 600 mm mehrfach nebeneinander in die Verleimpresse eingelegt werden. Auf diese Weise kann der Preßbereich optimal genutzt werden. Die Schlitze 7 erstrecken sich vorteilhaft über die halbe Breite der Auflagefläche 4. Die Anschlaglineale 6 sind abnehmbar am Pressentisch 2 vorgesehen. Auf diese Weise ist auch eine einfache Einstellung der Anschlaglineale 6 auf unterschiedlich dicke Hölzer 3 gewährleistet. Je nach Dicke der miteinander zu verleimenden Hölzer 3 werden unterschiedlich hohe Anschlaglineale in den Pressentisch 2 eingesetzt.The glueing press has a frame 1 on which a horizontal press table 2 is located. On it are to be pressed wood 3 during the pressing process. The press table 2 has a flat support surface 4, which is bounded on a longitudinal side by juxtaposed pressing elements 5. On the opposite longitudinal side are exemplified two aligned with each other stop rulers 6, with which the woods 3 are moved transversely to the longitudinal direction of the support surface 4 against the pressing elements 5. Depending on the size of the press table 2, only one or more stop rulers can be provided. They are moved in a manner to be described transversely to the longitudinal direction of the support surface 4. To guide the stop rulers 6 are in the support surface 4 parallel to each other lying slots 7 are provided which extend from the pressing elements 5 opposite longitudinal side approximately over half the width of the support surface 4. With the stop rulers 6 a very simple adjustment to the respective width of the plate 3 to be produced from the woods is possible. The stop rulers 6 extend overall over the length of the support surface 4, so that they can be fully utilized for pressing the woods 3. Thus, for example, with a possible press width of, for example, 1200 mm plates up to a width of 600 mm can be inserted several times side by side in the glueing press. In this way, the pressing area can be used optimally. The slots 7 advantageously extend over half the width of the support surface 4. The stop rulers 6 are provided detachably on the press table 2. In this way, a simple adjustment of the fence rulers 6 is guaranteed to different thicknesses of wood 3. Depending on the thickness of the wood to be glued together 3 different height fence rulers are used in the press table 2.

Die mit ihren verleimten Flächen aneinanderliegenden Hölzer 3 werden mit den Anschlaglinealen 6 bis zur Anlage an den Preßelementen 5 verschoben. Bevor der Preßdruck aufgebaut wird, wird ein Deckel 8 aus seiner Offenstellung (Fig. 2 bis 4) in seine Schließstellung abgesenkt. Der Deckel 8 ist an seiner Unterseite mit nebeneinander liegenden Druckleisten 9 versehen, die auf den Hölzern 3 aufliegen und diese bei entsprechender Druckbelastung in horizontaler Richtung gegeneinander ausrichten. Anschließend wird der auf die Preßelemente 5 wirkende Druck aufgebaut. Mit diesem Preßdruck werden die Hölzer 3 gegeneinander verpreßt. Sie werden durch die Anschlaglineale 6 während des Preßvorganges einwandfrei abgestützt. Zum Aushärten des Leimes zwischen den Hölzern 3 ist der Deckel 8 mit einer Heizeinrichtung versehen, die während des Preßvorganges eingeschaltet ist und zum Aushärten des Leims führt.The juxtaposed with their surfaces wood 3 are moved with the stop rulers 6 until it rests against the pressing elements 5. Before the pressing pressure is built up, a lid 8 from its open position ( Fig. 2 to 4 ) lowered into its closed position. The lid 8 is provided on its underside with adjacent pressure strips 9, which rest on the woods 3 and align them with a corresponding pressure load in the horizontal direction against each other. Subsequently, the force acting on the pressing elements 5 pressure is built up. With this pressing the woods 3 are pressed against each other. They are perfectly supported by the stop rulers 6 during the pressing process. To harden the glue between the woods 3, the cover 8 is provided with a heating device which is switched on during the pressing process and leads to the curing of the glue.

Die Preßelemente 5 sind auf einem Längsträger 10 gelagert, der sich an einer Längsseite des Pressentisches 2 befindet und durch eine Profilschiene (Fig. 11) gebildet ist. Der Längsträger 10 ist auf einem durch ein Viereckrohr gebildeten Träger 11 des Gestelles 1 befestigt. Der Längsträger 10 und der Träger 11 liegen übereinander und sind vorteilhaft gleich lang. Über die Länge des Längsträgers 10 verteilt befinden sich Versteifungselemente 12 (Fig. 1 bis 4), die vollständig innerhalb des Profils des Längsträgers 10 untergebracht sind.The pressing elements 5 are mounted on a longitudinal member 10, which is located on a longitudinal side of the press table 2 and by a rail ( Fig. 11 ) is formed. The longitudinal member 10 is mounted on a support 11 formed by a square tube 11 of the frame. The longitudinal member 10 and the carrier 11 are superposed and are advantageously the same length. Distributed over the length of the longitudinal member 10 are stiffening elements 12 ( Fig. 1 to 4 ), which are completely housed within the profile of the longitudinal member 10.

Die Preßelemente 5 sind in Richtung auf die Anschlaglineale 6 begrenzt verschiebbar. An ihrer von den Anschlaglinealen 6 abgewandten Seite liegen die Preßelemente 5 an einem flexiblen Schlauch 13 an (Fig. 8 und 11), der an beiden Enden geschlossen sowie an eine Druckluftquelle angeschlossen ist. Der Schlauch 13 erstreckt sich über die Länge des Längsträgers 10 und wird von einem U-Profilteil 14 aufgenommen, das auf dem Längsträger 10 befestigt ist. Die beiden horizontalen Schenkel 15, 16 des Profilteiles 14 erstrecken sich in Richtung auf die Anschlaglineale 6. Der die beiden Schenkel 15, 16 verbindende Steg 17 verläuft vertikal und deckt den Schlauch 13 ab, so daß er vor Beschädigung geschützt ist. Er liegt zwischen dem Steg 17 des Profilteiles 14 und den Preßelementen 5, die teilweise zwischen die Schenkel 15, 16 ragen. Die Preßelemente 5 erstrecken sich bis auf die Auflagefläche 4 des Pressentisches 2. Die Preßelemente 5 sind von Schrauben 18 oder dergleichen durchsetzt, die die Schenkel 15, 16 des Profilteiles 14 sowie einen oberen horizontalen Schenkel 19 des Längsträgers 10 durchsetzen. Die Durchtrittsöffnungen in den Preßelementen 5 für die Schrauben 18 sind so groß, daß die Preßelemente 5 begrenzt in Preßrichtung bewegt werden können.The pressing elements 5 are limitedly displaceable in the direction of the stop rulers 6. At their side remote from the stop rulers 6 side, the pressing elements 5 abut against a flexible hose 13 ( Fig. 8 and 11 ), which is closed at both ends and connected to a compressed air source. The hose 13 extends over the length of the longitudinal member 10 and is received by a U-profile part 14 which is mounted on the longitudinal member 10. The two horizontal legs 15, 16 of the profile member 14 extending in the direction of the stop rulers 6. The two legs 15, 16 connecting web 17 extends vertically and covers the hose 13, so that it is protected from damage. It lies between the web 17 of the profile part 14 and the pressing elements 5, which partially protrude between the legs 15, 16. The pressing elements 5 extend to the support surface 4 of the press table 2. The pressing elements 5 are penetrated by screws 18 or the like, which pass through the legs 15, 16 of the profile member 14 and an upper horizontal leg 19 of the longitudinal member 10. The passage openings in the pressing elements 5 for the screws 18 are so large that the pressing elements 5 can be moved limited in the pressing direction.

Wie sich aus den Fig. 7 und 8 ergibt, sind die Preßelemente 5 blockförmig ausgebildet und liegen unmittelbar aneinander. Die Preßelemente 5 sind an einer Seite mit einer vorstehenden, über ihre Höhe sich erstreckenden Feder 19 und an ihrer gegenüberliegenden Seite mit einer entsprechenden Vertiefung 20 versehen. Die nebeneinander liegenden Preßelemente 5 greifen mit den Federn 19 in die Vertiefungen 20 des jeweils benachbarten Preßelementes ein. Auf diese Weise sind die aneinanderliegenden Preßelemente gegeneinander ausgerichtet. Dabei ist diese Formschlußverbindung so gestaltet, daß sich benachbarte Preßelemente 5 noch geringfügig gegeneinander verschieben können.As is clear from the Fig. 7 and 8th results, the pressing elements 5 are block-shaped and lie directly against each other. The pressing elements 5 are on one side with a protruding, over its height extending spring 19 and on its opposite side with a corresponding recess 20 provided. The juxtaposed pressing elements 5 engage with the springs 19 in the recesses 20 of the respective adjacent pressing element. In this way, the adjacent pressing elements are aligned with each other. In this case, this positive connection is designed so that adjacent pressing elements 5 can still slightly move against each other.

Wie sich aus Fig. 2 ergibt, sind die Preßelemente 5 wesentlich schmaler als die zu verpressenden Hölzer 3. Dadurch können sich die einzelnen Preßelemente 5 optimal an die Hölzer 3 bzw. die aus ihnen herzustellende Platte anpassen. Die Vielzahl von Preßelementen 5 bildet eine Vielschieberleiste, an der die Hölzer 3 während des Preßvorganges anliegen. Wie Fig. 7 zeigt, bilden die Preßelemente 5 eine durchgehende Anschlagfläche 21 für die Hölzer 3. Da sich die Vielzahl von Preßelementen 5 flexibel an die Hölzer 3 anpassen kann, lassen sich auch Hölzer 3 mit sogenannten Spitzfugen ausdrücken, so daß eine einwandfreie Verpressung der Hölzer 3 gewährleistet ist.As it turned out Fig. 2 shows, the pressing elements 5 are much narrower than the wood to be pressed 3. This allows the individual pressing elements 5 optimally adapt to the woods 3 and the plate to be produced from them. The plurality of pressing elements 5 forms a multi-slider bar, against which the woods 3 during the pressing process. As Fig. 7 Since the plurality of pressing elements 5 can flexibly adapt to the woods 3, also wood 3 can be expressed with so-called pointed joints, so that a perfect compression of the woods 3 is guaranteed ,

Die Höhe der Preßelemente 5 ist auf die maximale Höhe der zu verpressenden Hölzer 3 abgestimmt, die sich parallel zu der Vielschieberleiste erstrekken.The height of the pressing elements 5 is matched to the maximum height of the wood to be pressed 3, which extend parallel to the Vielschieberleiste.

Die Hölzer 3 werden nach der Beleimung ihrer Längsseiten in ihrer Längsrichtung auf den Pressentisch 2 geschoben. Hierfür ist der Verleimpresse eine Beladeeinheit 91 vorgeschaltet (Fig. 5 und 6). Die Beladeeinheit 91 hat einen Auflagetisch 92, der um eine horizontale Achse schwenkbar ist. Fig. 5 zeigt den Auflagetisch 92 in der verschwenkten Lage, in der die miteinander zu verpressenden Hölzer 3 leicht auf den Auflagetisch 92 aufgelegt werden können. Der Auflagetisch 92 wird an seinen beiden Längsrändern von jeweils einer Profilschiene 93, 94 begrenzt. An der in der gekippten Lage unteren Profilschiene 93 werden die zu verpressenden Hölzer 3 angelegt. Da der Auflagetisch 92 gekippt werden kann, ist ein einfaches Beladen gewährleistet.The woods 3 are pushed after gluing their long sides in their longitudinal direction on the press table 2. For this purpose, the loading press is preceded by a loading unit 91 ( Fig. 5 and 6 ). The loading unit 91 has a support table 92, which is pivotable about a horizontal axis. Fig. 5 shows the support table 92 in the pivoted position in which the wood to be compressed 3 can be easily placed on the support table 92. The support table 92 is bounded at its two longitudinal edges by a respective profile rail 93, 94. At the lower in the tilted position rail 93 to be pressed wood 3 are created. Since the Auflagetisch 92 can be tilted, a simple loading is guaranteed.

Zum Verschieben des auf dem Auflagetisch 92 zusammengesetzten Lamellenpaketes dient ein Schieber 95, der auf einer Linearführung 22 verfahrbar ist. Sie erstreckt sich an der den Preßelementen 5 und der Profilschiene 93 gegenüberliegenden Längsseite des Pressentisches 2 in Längsrichtung der hintereinander liegenden Preßelemente 5 (Fig. 3, 4, 12 und 13) und des Auflagetisches 92. Die Linearführung 22 sitzt im Bereich des Pressentisches 2 auf einem horizontalen Schenkel 23 eines U-förmigen Längsträgers 24, der sich parallel zum Längsträger 10 am gegenüberliegenden Längsrand des Pressentisches 2 erstreckt. Der Längsträger 24 ist mit seinem anderen horizontalen Schenkel 25 auf einem Gestellträger 26 befestigt, der sich parallel zum Gestellträger 11 erstreckt. Die Linearführung 22 erstreckt sich auch über die Länge des Auflagetisches 92, so daß der Schieber 95 bis zu der von der Verleimpresse abgewandten Seite des Auflagetisches 92 verfahren werden kann.To move the assembled on the support table 92 disc pack is a slider 95 which is movable on a linear guide 22. It extends at the pressing elements 5 and the rail 93 opposite longitudinal side of the press table 2 in the longitudinal direction of the pressing elements 5 located one behind the other (FIG. Fig. 3 . 4 . 12 and 13 ) and the support table 92. The linear guide 22 is seated in the region of the press table 2 on a horizontal leg 23 of a U-shaped longitudinal member 24, which extends parallel to the longitudinal member 10 at the opposite longitudinal edge of the press table 2. The longitudinal member 24 is fastened with its other horizontal leg 25 on a rack support 26 which extends parallel to the frame carrier 11. The linear guide 22 also extends over the length of the support table 92, so that the slider 95 can be moved to the side facing away from the gluing press side of the support table 92.

Der Auflagetisch 92 schließt vorteilhaft lückenlos an den Pressentisch 2 an, so daß die Hölzer 3 durch den Schieber 95 problemlos vom Auflagetisch 92 auf den Pressentisch 2 geschoben werden können. Der Schieber 95 ist an einem auf der Linearführung 22 verfahrbaren Wagen gelagert. Damit der Schieber 95 beim Zurückfahren über auf dem Auflagetisch 92 aufgelegte Hölzer 3 gefahren werden kann, ist er am Wagen um eine horizontale, in Verfahrrichtung sich erstreckende Achse schwenkbar. Der Schieber 95 kann darum in hochgeschwenkter Lage über die Hölzer 3 gefahren und hinter ihnen wieder abgesenkt werden. Wird der Schieber 95 anschließend wieder in Richtung auf die Verleimpresse verfahren, nimmt er die Hölzer 3 mit. Auf diese Weise kann auf dem Auflagetisch 92 das nächste Lamellenpaket zusammengestellt werden, während der Schieber 95 zum Pressentisch 2 fährt.The support table 92 advantageously connects completely to the press table 2, so that the woods 3 can be easily pushed by the slider 95 from the support table 92 onto the press table 2. The slider 95 is mounted on a movable carriage on the linear guide 22. So that the slider 95 can be moved when driving back over laid on the support table 92 timbers 3, it is on the car about a horizontal, in the direction of travel extending axis swiveled. The slider 95 can therefore be driven in the swung-up position on the woods 3 and lowered back behind them. If the slider 95 is subsequently moved again in the direction of the gluing press, it takes the woods 3 with it. In this way, on the support table 92, the next disc pack can be assembled while the slider 95 moves to the press table 2.

Die Gestellträger 11, 26 und die Längsträger 10, 24 liegen jeweils auf gleicher Höhe (Fig. 4). Zwischen den Längsträgern 10, 24 ist der Pressentisch 2 befestigt. Mit dem Schieber 95 können die Hölzer 3 in ihrer Längsrichtung in den Preßbereich geschoben und nach dem Preßvorgang aus ihm herausgeschoben werden. Da die Befüllung der Verleimpresse in Längsrichtung des Pressentisches 2 und damit senkrecht zur Preßrichtung erfolgt, ist ein einfaches und rasches Befüllen der Verleimpresse gewährleistet. Nach dem Einschieben der aneinanderliegenden Hölzer 3 werden die Anschlaglineale 6 quer zur Einschubrichtung auf dem Pressentisch 2 so weit verfahren, bis die Hölzer 3 an den Preßelementen 5 anliegen. In den Fig. 4 und 11 haben die Hölzer 3 noch Abstand von den Preßelementen 5. Die Hölzer werden in der beschriebenen Weise mittels der Anschlaglineale 6 bis zur Anlage an den Preßelementen 5 auf der Auflagefläche 4 des Pressentisches 2 verschoben. Die Preßelemente 5 sind vollständig in Richtung auf die Auflagefläche 4 ausgefahren. Hierzu wird der Schlauch 13 mit Druckluft gefüllt. Er dehnt sich entsprechend aus und verschiebt dadurch die Preßelemente 5 in die voll ausgefahrene Stellung. Hierfür reicht ein geringer Druck des Druckmediums im Schlauch 13 aus. Wenn die Hölzer 3 mit den Anschlaglinealen 6 gegen die Preßelemente 5 geschoben werden, können sich diese relativ zueinander geringfügig verschieben, je nach Ausbildung bzw. Verlauf des Anlagerandes der Hölzer 3. Der elastisch verformte Schlauch 13 sorgt dafür, daß die Preßelemente 5 am Rand der Hölzer 3 anliegen.The rack support 11, 26 and the side members 10, 24 are each at the same height ( Fig. 4 ). Between the longitudinal members 10, 24 of the press table 2 is fixed. With the slider 95, the woods 3 can be pushed in its longitudinal direction in the pressing area and pushed out of it after the pressing process. Since the filling of the gluing press takes place in the longitudinal direction of the press table 2 and thus perpendicular to the pressing direction, a simple and rapid filling of the gluing press is ensured. After insertion of the adjoining woods 3, the stop rulers 6 are moved transversely to the direction of insertion on the press table 2 until the woods 3 bear against the pressing elements 5. In the Fig. 4 and 11 the woods 3 are still at a distance from the pressing elements 5. The woods are moved in the manner described by means of the stop rulers 6 to the contact with the pressing elements 5 on the support surface 4 of the press table 2. The pressing elements 5 are fully extended in the direction of the support surface 4. For this purpose, the tube 13 is filled with compressed air. He expands accordingly and thus moves the pressing elements 5 in the fully extended position. For this purpose, a low pressure of the pressure medium in the hose 13 is sufficient. If the woods 3 are pushed with the stop rulers 6 against the pressing elements 5, they can move relative to each other slightly, depending on the training or course of investment edge of the woods 3. The elastically deformed tube 13 ensures that the pressing elements 5 at the edge of Woods 3 abut.

Die Anschlaglineale 6 erstrecken sich parallel zur Linearführung 22 (Fig. 2 bis 4) und greifen mit an ihrer Unterseite vorgesehenen Schwertern 27 durch die Schlitze 7 des Pressentisches 2 (Fig. 13). Die Anschlaglineale 6 haben vorteilhaft jeweils zwei solcher Schwerter 27 nahe ihren Enden. Wie sich aus Fig. 15 ergibt, greifen diese Schwerter 27 in Schlitten 28, 29 formschlüssig ein, die an einem (nicht dargestellten) Rahmen vorgesehen sind, der an der Unterseite des Pressentisches 2 verschiebbar angeordnet ist. Die Schlitten 28, 29 sind in den Schlitzen 7 formschlüssig geführt. An ihren einander zugewandten Seiten sind die Schlitten 28, 29 mit einer als Vertiefung ausgebildeten Aufnahme 30, 31 versehen, die sich über die Länge der Schlitten erstreckt und in die eine Führungsleiste 32, 33 eingreift, die an einer Seitenwand des Schlitzes 7 befestigt ist.The stop rulers 6 extend parallel to the linear guide 22 (FIG. Fig. 2 to 4 ) and grip with provided on its underside swords 27 through the slots 7 of the press table 2 ( Fig. 13 ). The stop rulers 6 advantageously each have two such swords 27 near their ends. As it turned out Fig. 15 results, these swords 27 engage in a form-fitting manner in slides 28, 29, which are provided on a (not shown) frame, which is slidably disposed on the underside of the press table 2. The carriages 28, 29 are guided positively in the slots 7. At their sides facing each other, the carriages 28, 29 are formed with a depression Receiving 30, 31 is provided, which extends over the length of the carriage and in which a guide rail 32, 33 which is fixed to a side wall of the slot 7.

In Fig. 15 sind lediglich die benachbarten Schlitten 28, 29 der beiden Anschlaglineale 6 dargestellt. An den anderen Enden der Anschlaglineale sind entsprechende Schlitten vorgesehen.In Fig. 15 only the adjacent carriages 28, 29 of the two stop rulers 6 are shown. At the other ends of the fence rulers corresponding slides are provided.

Für den Antrieb der Anschlaglineale 6 ist ein Hydromotor 34 vorgesehen, der an einem Ende der Verleimpresse angeordnet ist (Fig. 14). Der Hydromotor 34 ist am vertikalen Steg 35 des Längsträgers 24 befestigt. Der Einsatz eines Hydromotors gibt die Möglichkeit, mit Drosseln und Druckminderern auf einfache Weise die Geschwindigkeit und die Zustellkräfte der Anschlaglineale 6 einzustellen.For driving the stop rulers 6, a hydraulic motor 34 is provided, which is arranged at one end of the glue-laying press ( Fig. 14 ). The hydraulic motor 34 is attached to the vertical web 35 of the longitudinal member 24. The use of a hydraulic motor makes it possible to adjust the throttling and pressure reducers in a simple manner, the speed and the Zustellkräfte the stop rulers 6.

Wie Fig. 14 zeigt, ist der Hydromotor 34 über einen Endlostrieb 36 mit einer Spindel 37 antriebsverbunden. Sie wiederum ist über einen weiteren Endlostrieb 38 mit einer Spindel 39 antriebsverbunden, die ihrerseits über einen Endlostrieb 40 mit einer Spindel 41 antriebsverbunden ist. Die Spindeln 37, 39, 41 liegen parallel zueinander und erstrecken sich in Verschieberichtung der Anschlaglineale 6. Die Spindeln 37, 39, 41 sind im Pressentisch 2 drehbar gelagert. Auf den Spindeln sitzt, wie dies in Fig. 15 für die Spindel 39 dargestellt ist, eine Spindelmutter 42, die durch Drehen der Spindel in die entsprechende Richtung verschoben wird. Die Spindelmutter 42 ist in einer Vertiefung 43 in der Unterseite des Pressentisches 2 längsverschieblich geführt. Dadurch wird auch sichergestellt, daß die Spindelmutter 42 nicht um ihre Achse dreht, sondern zuverlässig verschoben wird. Auf den anderen Spindeln 37 und 41 sitzt jeweils eine entsprechende Spindelmutter, die in Verschieberichtung der Anschlaglineale 6 über den Rahmen fest mit ihnen verbunden ist. Die Anschlaglineale 6 greifen mit ihren Schwertern 27 in die entsprechenden Schlitten ein. Über den gemeinsamen Hydromotor 34 werden somit beide Anschlaglineale 6 gleichzeitig und in gleichem Maße verschoben.As Fig. 14 shows, the hydraulic motor 34 is drivingly connected via a Endlodrieb 36 with a spindle 37. In turn, it is drivingly connected via a further endless drive 38 to a spindle 39, which in turn is drive-connected to a spindle 41 via a endless drive 40. The spindles 37, 39, 41 are parallel to each other and extend in the direction of displacement of the stop rulers 6. The spindles 37, 39, 41 are rotatably mounted in the press table 2. Sitting on the spindles, like this in Fig. 15 is shown for the spindle 39, a spindle nut 42 which is displaced by rotating the spindle in the corresponding direction. The spindle nut 42 is longitudinally displaceably guided in a recess 43 in the underside of the press table 2. This also ensures that the spindle nut 42 does not rotate about its axis, but is reliably displaced. On the other spindles 37 and 41 is seated in each case a corresponding spindle nut which is connected in the direction of displacement of the stop rulers 6 on the frame fixed to them. The stop rulers 6 engage with their swords 27 in the corresponding carriage. Be about the common hydraulic motor 34 thus both stop rulers 6 moved simultaneously and to the same extent.

Der Deckel 8 ist an seinem von den Druckelementen 5 abgewandten Rand höhenverstellbar am Gestell 1 gelagert. Der Deckel 8 hat an seinen beiden Enden jeweils einen plattenförmigen Träger 44. Die Träger 44 befinden sich unterhalb einer Schutzabdeckung 45, von denen in Fig. 14 nur die eine Schutzabdeckung dargestellt ist.The lid 8 is mounted vertically adjustable on the frame 1 at its side remote from the printing elements 5 edge. The lid 8 has at its two ends in each case a plate-shaped carrier 44. The carrier 44 are located below a protective cover 45, of which in Fig. 14 only one protective cover is shown.

Die Träger 44 liegen parallel zu plattenförmigen Ständern 46, 47, die mit ihrem unteren Ende auf einer Bodenplatte 48 des Gestelles 1 befestigt sind. In Fig. 16 sind lediglich die Ständer 46, 47 dargestellt, nicht jedoch die Träger 44 des Deckels 8. Die parallel zueinander liegenden Ständer 46, 47 haben jeweils ein in Höhenrichtung verlaufendes Langloch 49, 50. Zwischen den Ständern 46, 47 befindet sich ein Rohr 51, das mit den unteren Enden der Träger 44 verbunden ist. Über die Länge der Langlöcher 49, 50 kann das Rohr 51 begrenzt in der Höhe verschoben werden.The carriers 44 are parallel to plate-shaped uprights 46, 47, which are fastened with their lower end on a bottom plate 48 of the frame 1. In Fig. 16 only the uprights 46, 47 are shown, but not the carrier 44 of the lid 8. The mutually parallel stator 46, 47 each have a running in the vertical direction slot 49, 50. Between the uprights 46, 47 is a tube 51, the is connected to the lower ends of the carrier 44. Over the length of the slots 49, 50, the tube 51 can be moved limited in height.

Wie sich aus Fig. 14 ergibt, sind in die beiden Enden des Rohres 51 Spindelmuttern 52, 53 mit Steckansätzen 54, 55 gesteckt. Sie haben unrunden, vorzugsweise eckigen Querschnitt und sitzen drehfest im Rohr 51. Die Steckansätze 54, 55 durchsetzen die Träger 44 sowie die Langlöcher 49, 50 in den Ständern 46, 47. Die Spindelmuttern 52, 53 liegen an den voneinander abgewandten Außenseiten der Deckelträger 44, die ihrerseits mit geringem Abstand auf den voneinander abgewandten Seiten der Ständer 46, 47 angeordnet sind. Die Spindelmuttern 52, 53 sitzen auf vertikalen Spindeln 56, 57, die auf der Bodenplatte 48 drehbar gelagert sind. Der Antrieb der Spindeln 56, 57 erfolgt von einem Hydromotor 58 aus, der im Bereich zwischen den beiden Ständern 46, 47 auf der Bodenplatte 48 gelagert ist. Über zwei Kettentriebe 59, 60 werden die Spindeln 56, 57 vom Hydromotor 58 angetrieben. Je nach Drehrichtung der Spindeln 56, 57 wird der Deckel 8 über die Deckelträger 44 nach oben oder nach unten verstellt.As it turned out Fig. 14 results in the two ends of the tube 51 spindle nuts 52, 53 are plugged with lugs 54, 55. The plug lugs 54, 55 pass through the carrier 44 and the slots 49, 50 in the uprights 46, 47. The spindle nuts 52, 53 are located on the opposite outer sides of the lid support 44th , which in turn are arranged at a small distance on the opposite sides of the stands 46, 47. The spindle nuts 52, 53 are seated on vertical spindles 56, 57 which are rotatably mounted on the bottom plate 48. The drive of the spindles 56, 57 is carried out by a hydraulic motor 58 which is mounted in the region between the two uprights 46, 47 on the bottom plate 48. About two chain drives 59, 60, the spindles 56, 57 are driven by the hydraulic motor 58. Depending on the direction of rotation of the spindles 56, 57, the cover 8 is moved over the cover support 44 upwards or downwards.

Der Einsatz der Spindel 56, 57 zur Höhenverstellung des Deckels 8 hat den Vorteil, daß nur eine geringe Kraft zum Verstellen des Deckels notwendig ist. Durch die Selbsthemmung des Spindelgewindes können große Spannkräfte ausgeübt werden. Außerdem ist der Spindelantrieb zuverlässig. Das selbsthemmende Spindelgewinde verhindert außerdem, daß der Deckel 8 nach unten fällt.The use of the spindle 56, 57 for height adjustment of the lid 8 has the advantage that only a small force to adjust the lid is necessary. Due to the self-locking of the spindle thread large clamping forces can be exercised. In addition, the spindle drive is reliable. The self-locking spindle thread also prevents the cover 8 falls down.

Die Steckansätze 54, 55 sind in den Langlöchern 49, 50 mit Gleit- oder Wälzlagern geführt, so daß eine leichtgängige Verschiebbarkeit gewährleistet ist.The insertion lugs 54, 55 are guided in the slots 49, 50 with sliding or rolling bearings, so that a smooth displacement is guaranteed.

Wie Fig. 16 zeigt, ist nahe dem oberen Ende der Ständer 46, 47 ein Kulissenstein 61 vorgesehen, der vorteilhaft eine frei drehbare Rolle ist. Der Deckel 8 ist mit Kulissenführungen 62 versehen, in die der jeweilige Kulissenstein 61 eingreift. Die Kulissenführungen 62 haben einen oberen, vertikal verlaufenden Führungsabschnitt 63, der nach unten in einen schrägen Führungsabschnitt 64 übergeht. Die Kulissenführungen 62 können beispielhaft durch parallel zueinander liegende, stumpfwinklig abgewinkelte Leisten 65, 66 gebildet sein, die an der Innenseite der Deckelträger 44 befestigt sind.As Fig. 16 shows, near the upper end of the stator 46, 47, a sliding block 61 is provided, which is advantageously a freely rotatable roller. The lid 8 is provided with slide guides 62, in which the respective sliding block 61 engages. The slotted guides 62 have an upper, vertically extending guide section 63, which merges downwards into an oblique guide section 64. The slide guides 62 may be formed, for example, by mutually parallel, obtuse angled strips 65, 66 which are fastened to the inside of the cover carrier 44.

Ist der Deckel 8 in seiner unteren Schließlage, liegen die Kulissensteine 61 in den vertikalen Führungsabschnitten 63 der Kulissenführungen 62. Werden die Deckelträger 44 durch Betätigen der Spindeln 56, 57 nach oben verschoben, bleibt der Deckel 8 zunächst in seiner horizontalen Lage, solange die Kulissensteine 61 in den vertikalen Führungsabschnitten 63 liegen. Beim weiteren Anheben des Deckels 8 gelangen die Kulissensteine 61 in die schrägen Führungsabschnitte 64, wodurch der Deckel 8 aus seiner horizontalen Öffnungsstellung (Fig. 2) bei der weiteren Höhenverstellung in eine schräge Öffnungsstellung (Fig. 3) gelangt. Bei dieser beschriebenen Höhenverstellung wird der Deckel 8 am Ende seines Verstellweges gleichzeitig nach hinten geschwenkt. Dadurch wird die Zugänglichkeit in das Preßbett erleichtert. Die Deckelträger 44 schwenken bei dieser Öffnungsbewegung um die Achse des Rohres 51. Der maximale Verschiebeweg des Deckels 8 wird durch die Länge der Langlöcher 49, 50 bestimmt.If the lid 8 in its lower closed position, the sliding blocks 61 are in the vertical guide portions 63 of the slotted guides 62. If the lid carrier 44 by pressing the spindles 56, 57 shifted upward, the lid 8 initially remains in its horizontal position as long as the sliding blocks 61 lie in the vertical guide portions 63. Upon further lifting of the cover 8, the sliding blocks 61 pass into the oblique guide sections 64, whereby the cover 8 is moved out of its horizontal open position (FIG. Fig. 2 ) in the further height adjustment in an oblique opening position ( Fig. 3 ). In this described height adjustment of the cover 8 is pivoted at the end of its adjustment simultaneously backwards. This will increase the accessibility in the press bed facilitated. The cover carrier 44 pivot in this opening movement about the axis of the tube 51. The maximum displacement of the lid 8 is determined by the length of the slots 49, 50.

Die an der Unterseite des Deckels befindlichen Druckleisten 9 bilden eine Druckplatte 67, die während des Preßvorganges auf den Hölzern 3 der zu verpressenden Platte unter Druck aufliegt. Die Druckleisten 9 erstrecken sich parallel zu den Hölzern 3 nahezu über die gesamte Länge des Pressentisches 2 (Fig. 7). Die Druckleisten 9 haben eine ebene Unterseite 68. In halber Breite steht von den Druckleisten 9 nach oben ein Profilkörper 69 ab, der in jeweils einer C-förmigen Profilschiene 70 gehalten ist. Die auf gleicher Höhe gegeneinander gerichteten Schenkelenden 71, 72 untergreifen den jeweiligen Profilkörper 69. Die Profilschienen 70 sind geringfügig kürzer als die Druckleisten 9 (Fig. 7 und 8) und an zwei mit Abstand zueinander liegenden Traversen 73, 74 befestigt. Sie sind ihrerseits an der Unterseite des Deckels 8 gehalten. An der Innenseite der Stege 75 der Profilschienen 70 ist jeweils ein Schlauch 76 befestigt. Er hat etwa rechteckigen Querschnitt und liegt mit einer dickeren Seite 77 an der Innenseite des Steges 75 der Profilschienen 70 an. Die gegenüberliegende, den Druckleisten 9 zugewandte Seite 78 der Schläuche 76 ist dünnwandig ausgebildet. Die Schläuche erstrecken sich etwa über die Länge der Druckleisten 9 und sind an ihren beiden Enden geschlossen. Etwa in halber Länge sind die Schläuche 76 mit jeweils einem Anschluß 79 versehen (Fig. 7), über die die Schläuche 76 an eine Druckluftquelle angeschlossen sind.The located on the underside of the lid pressure strips 9 form a pressure plate 67 which rests under pressure during the pressing operation on the woods 3 to be pressed plate. The pressure bars 9 extend parallel to the woods 3 almost over the entire length of the press table 2 (FIG. Fig. 7 ). The pressure bars 9 have a flat bottom 68. Halfway from the pressure bars 9 upwards from a profile body 69, which is held in each case a C-shaped rail 70. The leg ends 71, 72 directed at the same height engage under the respective profile body 69. The profile rails 70 are slightly shorter than the pressure strips 9 (FIG. Fig. 7 and 8th ) and on two mutually spaced trusses 73, 74 attached. They are in turn held on the underside of the lid 8. On the inside of the webs 75 of the profile rails 70, a hose 76 is attached in each case. He has approximately rectangular cross-section and is with a thicker side 77 on the inside of the web 75 of the rails 70 at. The opposite, the pressure bars 9 facing side 78 of the tubes 76 is thin-walled. The hoses extend approximately over the length of the pressure strips 9 and are closed at both ends. About halfway through the tubes 76 are each provided with a terminal 79 ( Fig. 7 ), via which the hoses 76 are connected to a compressed air source.

Ist der Deckel 8 angehoben (Fig. 2 und 3), dann hängen die Druckleisten 9 mit ihren Profilkörpern 69 auf den Schenkelenden 71, 72 der Profilschienen 70 (Fig. 10). In dieser Lage hat die Schlauchseite 78 Abstand vom Boden 80 einer Vertiefung 81 in der dem Steg 75 der Profilschienen 70 zugewandten Oberseite 82 des Profilkörpers 69. Die quer zur Längsrichtung der Druckleisten 9 gemessene Breite der Vertiefungen 81 entspricht etwa der entsprechenden Breite des Schlauches 76. Wird der Deckel 8 aus der Offenstellung mittels der Spindeln 56, 57 in der beschriebenen Weise abgesenkt, kommt die Druckplatte 67 zur Auflage auf den Hölzern 3. Die Schläuche 76 sind mit dem Druckmedium gefüllt. Da die Druckleisten 9 unabhängig voneinander begrenzt höhenbeweglich in den Profilschienen 70 gelagert sind, können sie sich optimal an die Oberseite der zu verpressenden Platte anpassen. Durch die unter Druck stehenden Schläuche 76 werden die einzelnen Druckleisten 9 zusätzlich nach unten gedrückt, wodurch die Ausrichtung der lamellenförmigen Hölzer 3 noch verbessert wird. Über die mit Druckluft gefüllten Schläuche 76 wird während des Preßvorganges der erforderliche Spanndruck auf die Hölzer 3 aufgebracht. Die Schenkelenden 71, 72 der Profilschienen 70 haben in der Hängelage der Druckleisten 9 einen ausreichend großen Abstand von deren Oberseite, so daß nach dem Aufliegen der Druckleisten 9 auf den Hölzern 3 beim weiteren Absenken des Deckels 8 und damit der Profilschienen 70 die Profilkörper 69 an den Schläuchen 76 zur Anlage kommen, bevor die Schenkelenden 71, 72 an den Druckleisten 9 anliegen. Dadurch kann ein ausreichend hoher Spanndruck erzeugt werden.Is the lid 8 raised ( Fig. 2 and 3 ), then the pressure bars 9 hang with their profile bodies 69 on the leg ends 71, 72 of the profile rails 70 (FIG. Fig. 10 ). In this position, the hose side 78 has a distance from the bottom 80 of a recess 81 in the web 75 of the rails 70 facing top 82 of the profile body 69. The transverse to the longitudinal direction of the pressure bars 9 measured width of the wells 81 corresponds approximately to the corresponding width of the tube 76th If the lid 8 from the open position lowered by means of the spindles 56, 57 in the manner described, the pressure plate 67 comes to rest on the wood 3. The hoses 76 are filled with the pressure medium. Since the pressure bars 9 are mounted independently of each other limited height movable in the rails 70, they can optimally adapt to the top of the plate to be pressed. Due to the pressurized hoses 76, the individual pressure strips 9 are additionally pressed down, whereby the orientation of the lamellar woods 3 is still improved. About the filled with compressed air hoses 76 the required clamping pressure is applied to the woods 3 during the pressing process. The leg ends 71, 72 of the rails 70 have in the hanging position of the pressure bars 9 a sufficiently large distance from the top, so that after resting the pressure bars 9 on the wood 3 in further lowering the lid 8 and thus the rails 70, the profile body 69 at the hoses 76 come to rest before the leg ends 71, 72 abut the pressure bars 9. As a result, a sufficiently high clamping pressure can be generated.

Die Druckleisten 9 sind an der Unterseite 68 von einer blechförmigen Heizelektrode 83 bedeckt, mit der die Druckplatte 67 während des Preßvorganges auf den Hölzern 3 aufliegt. An den Längsseiten 84 ist die Elektrode 83 U-förmig gebogen. An den Schmalseiten 85 ist die Elektrode 83 nach oben rechtwinklig abgewinkelt. Die Druckleisten 9 liegen mit ihren Schmalseiten an den abgewinkelten Schmalseiten 85 der Elektrode 83 an. Die an den Längsseiten des Pressentisches 2 befindlichen Druckleisten 9 sind mit einer über ihre Länge sich erstreckenden Nut 86 versehen, die in Richtung auf die Unterseite 68 der Druckleiste 9 durch einen über seine Länge durchgehenden Steg 87 begrenzt ist. Er wird von der U-förmig gebogenen Längsseite 84 der Flächenelektrode 83 umgriffen. Auf diese Weise ist die Elektrode 83 sicher an der Druckplatte 87 gehalten.The pressure bars 9 are covered on the underside 68 by a sheet-shaped heating electrode 83, with which the pressure plate 67 rests on the wood 3 during the pressing process. On the longitudinal sides 84, the electrode 83 is bent in a U-shape. On the narrow sides 85, the electrode 83 is angled upward at right angles. The pressure strips 9 rest with their narrow sides against the angled narrow sides 85 of the electrode 83. The pressure strips 9 located on the longitudinal sides of the press table 2 are provided with a groove 86 extending over their length, which is bounded in the direction of the underside 68 of the pressure strip 9 by a web 87 extending over its length. It is encompassed by the U-shaped longitudinal side 84 of the surface electrode 83. In this way, the electrode 83 is securely held on the pressure plate 87.

Vorteilhaft sind sämtliche Druckleisten 9 mit der beschriebenen Nut 86 versehen, so daß jede Druckleiste 9 als Einhängeleiste für die Elektrode 83 verwendet werden kann. An die Elektrode 83, welche die Unterseite der Druckplatte 67 vollständig abdeckt, wird während des Preßvorganges Strom angelegt. Der Pressentisch 2 bzw. das Gestell 1 fungieren als Masse (Minuspol). Die Elektrode 83 ist Teil einer Hochfrequenzheizung, mit der während des Preßvorganges der Leim zwischen den lamellenförmigen Hölzern 3 ausgehärtet werden kann. Die Druckleisten 9 bestehen aus elektrisch isolierendem Material, wie Holz, Kunststoff und dergleichen.Advantageously, all pressure strips 9 are provided with the described groove 86, so that each pressure bar 9 used as a suspension strip for the electrode 83 can be. To the electrode 83, which completely covers the underside of the pressure plate 67, current is applied during the pressing process. The press table 2 and the frame 1 act as mass (negative pole). The electrode 83 is part of a high-frequency heating, with which the glue between the lamellar woods 3 can be cured during the pressing process. The pressure bars 9 are made of electrically insulating material, such as wood, plastic and the like.

Die lamellenförmigen Hölzer 3 werden außerhalb des Pressentisches 2 in der Beladeeinheit 91 mit ihren verleimten Längsseiten aneinandergelegt. Mit dem Schieber 95 wird dieses so zusammengelegte Paket auf den Pressentisch 2 geschoben. Der Schieber 95 wird hierbei längs der Linearführung 22 verschoben. Da sie sich über die gesamte Länge des Pressentisches 2 erstreckt, kann der Schieber 95 bis zum Ende des Pressentisches 2 verfahren werden, so daß mit ihm nach dem Preßvorgang die verpreßten Hölzer 3 vollständig vom Pressentisch 2 geschoben werden können. Während dieses Beladevorganges des Pressentisches 2 befinden sich die Anschlaglineale 6 vorteilhaft in ihrer Ausgangsstellung, in der sie den größten Abstand von den gegenüberliegenden Preßelementen 5 haben (Fig. 3). Es ist selbstverständlich möglich, die Anschlaglineale 6 in Richtung auf die Preßelemente 5 zu verstellen, wenn die Länge der zu verpressenden Platte entsprechend klein ist. Die lamellenförmigen Hölzer 3 werden so auf den Pressentisch 2 geschoben, daß sie sich parallel zu der aus den Preßelementen 5 gebildeten Druckleiste erstrecken (Fig. 3). Je nach Länge der Hölzer 3 können mehrere Pakete hintereinander auf den Pressentisch 2 geschoben werden. Während dieses Einschiebevorganges ist der über die Länge der Druckleiste sich erstreckende Schlauch 13 mit Druckluft gefüllt.The lamellar woods 3 are placed against each other outside the press table 2 in the loading unit 91 with their glued longitudinal sides. With the slider 95, this so-folded package is pushed onto the press table 2. The slider 95 is in this case moved along the linear guide 22. Since it extends over the entire length of the press table 2, the slider 95 can be moved to the end of the press table 2, so that with him after the pressing the compressed wood 3 can be pushed completely from the press table 2. During this loading process of the press table 2, the stop rulers 6 are advantageously in their starting position, in which they have the greatest distance from the opposite press elements 5 ( Fig. 3 ). It is of course possible to adjust the stop rulers 6 in the direction of the pressing elements 5, if the length of the plate to be pressed is correspondingly small. The lamellar woods 3 are pushed onto the press table 2 in such a way that they extend parallel to the pressure strip formed by the pressing elements 5 ( Fig. 3 ). Depending on the length of the woods 3 several packages can be pushed one behind the other onto the press table 2. During this Einschiebevorganges over the length of the pressure bar extending hose 13 is filled with compressed air.

Die Anschlaglineale 6 werden anschließend mittels des Hydromotors 34 und der Spindeln 37, 39, 41 in Richtung auf die Preßelemente 5 auf dem Pressentisch 2 verfahren. Mit den Anschlaglinealen 6 werden die zusammengestellten Platten gegen die Preßelemente 5 geschoben. Da über die Länge der Hölzer 3 eine Vielzahl von Preßelementen 5 vorgesehen ist, die sich begrenzt relativ zueinander verschieben können, ist gewährleistet, daß die Preßelemente 5 optimal am entsprechenden Rand der zu verpressenden Platte anliegen. Mit den Spindeln 37, 39, 41 wird der unter dem Pressentisch 2 befindliche Rahmen motorisch auf die entsprechende Preßbreite gefahren. Mit den Spindeln 37, 39, 41 kann während des Preßvorganges die Preßkraft einwandfrei aufgenommen werden. Die Spindeln 37, 39, 41 sind mit einem selbsthemmenden Gewinde versehen, so daß die Anschlaglineale 6 die Hölzer 3 sicher gegen den Preßdruck abstützen können. Zur Erzeugung der Preßkraft wird das Druckmedium im Schlauch 13 durch die Preßelemente 5 unter einen so hohen Druck gesetzt, daß dadurch die Preßelemente 5 mit entsprechender Kraft gegen das zu verpressende Paket gedrückt werden. Die Spindeln 37, 39, 41 können die Preßkraft einwandfrei aufnehmen. Da die Anschlaglineale 6 die Hölzer 3 gegen die Preßelemente 5 verschieben, müssen die Preßelemente 5 für den Preßvorgang nur einen geringen Hub ausführen. Durch die Vielzahl der Preßelemente 5 ist auch gewährleistet, daß die Hölzer 3 nicht genau gegenüber den Preßelementen 5 ausgerichtet werden müssen.The stop rulers 6 are then moved by means of the hydraulic motor 34 and the spindles 37, 39, 41 in the direction of the pressing elements 5 on the press table 2. With the stop rulers 6, the assembled plates are pushed against the pressing elements 5. Because of the length the woods 3 a plurality of pressing elements 5 is provided, which can move limited limited relative to each other, it is ensured that the pressing elements 5 rest optimally on the corresponding edge of the plate to be pressed. With the spindles 37, 39, 41 of the frame located under the press table 2 is driven by a motor to the appropriate press width. With the spindles 37, 39, 41, the pressing force can be properly absorbed during the pressing process. The spindles 37, 39, 41 are provided with a self-locking thread, so that the stop rulers 6, the woods 3 can be securely supported against the pressing pressure. To generate the pressing force, the pressure medium in the tube 13 is set by the pressing elements 5 under such a high pressure that thereby the pressing elements 5 are pressed with appropriate force against the package to be pressed. The spindles 37, 39, 41 can absorb the pressing force properly. Since the stop rulers 6 move the woods 3 against the pressing elements 5, the pressing elements 5 must perform only a small stroke for the pressing. Due to the large number of pressing elements 5 it is also ensured that the woods 3 need not be aligned exactly opposite the pressing elements 5.

Bevor der Preßdruck aufgebaut wird, wird der Deckel 8 in der beschriebenen Weise motorisch geschlossen. Die Druckleisten 9 mit der Flächenelektrode 83 kommen auf den lamellenförmigen Hölzern 3 des Paketes zur Auflage, wodurch sie vertikal ausgerichtet werden. Die Druckleisten 9 werden in der beschriebenen Weise durch die Schläuche 76 nach unten gedrückt, wodurch die vertikale Ausrichtung der lamellenförmigen Hölzer 3 noch verbessert wird. Sobald dieser Spanndruck aufgebaut ist, wird der Preßdruck durch die beschriebene Erhöhung des Druckes im Schlauch 13 erzeugt, wodurch die Hölzer 3 quer zu ihrer Längsrichtung mit hoher Kraft verpreßt werden. Durch diesen hohen Preßdruck werden die Hölzer 3 gegeneinander gepreßt und entsprechend geringfügig in Preßrichtung verschoben. Dabei werden die auf den Hölzern 3 aufliegenden Druckleisten 9 entsprechend geringfügig mitgenommen. Zu diesem Zweck sind die Profilschienen 70 mit jeweils zwei Haltelaschen 96 versehen (Fig. 7), die eine Platte 97, 98 übergreifen, die an der Unterseite der Traversen 73, 74 befestigt ist. Die Platten 97, 98 sind länger als die Druckplatte 67. Die Haltelaschen 96 mit den an ihnen mit Schrauben 99 befestigten Druckleisten 9 sind geringfügig in Längsrichtung der Traversen 73, 74 und damit in Preßrichtung verschiebbar. Da die Druckleisten 9 unter Spanndruck auf den Hölzern 3 aufliegen, die unter dem Preßdruck auf der Auflagefläche 4 des Pressentisches 2 geringfügig in Richtung auf die Anschlaglineale 6 verschoben werden, kann die entstehende Reibkraft optimal aufgenommen und abgebaut werden.Before the pressing pressure is built up, the cover 8 is closed by a motor in the manner described. The pressure bars 9 with the surface electrode 83 come to the lamellar woods 3 of the package to the support, whereby they are aligned vertically. The pressure bars 9 are pressed in the manner described by the tubes 76 down, whereby the vertical alignment of the lamellar woods 3 is still improved. Once this clamping pressure is built up, the pressing pressure is generated by the described increase in the pressure in the tube 13, whereby the woods 3 are pressed transversely to its longitudinal direction with high force. By this high pressure, the woods 3 are pressed against each other and moved accordingly slightly in the pressing direction. The resting on the wood 3 pressure bars 9 are taken accordingly slightly. For this purpose, the profile rails 70, each with two retaining tabs 96 provided ( Fig. 7 ), which engage over a plate 97, 98, which is fixed to the underside of the trusses 73, 74. The plates 97, 98 are longer than the pressure plate 67. The retaining tabs 96 with the attached to them with screws 99 pressure bars 9 are slightly displaced in the longitudinal direction of the trusses 73, 74 and thus in the pressing direction. Since the pressure bars 9 rest under clamping pressure on the wood 3, which are slightly shifted under the pressing pressure on the support surface 4 of the press table 2 in the direction of the stop rulers 6, the resulting frictional force can be optimally absorbed and reduced.

Beim Preßvorgang wird die Hochfrequenzheizung eingeschaltet, so daß der zwischen den Hölzern 3 befindliche Leim rasch aushärtet. Damit die bei der Hochfrequenzbeheizung entstehende Strahlung nicht nach außen gelangt, sind am Rand des Deckels 8 Schürzen 100 befestigt (Fig. 1 bis 4), die bei abgesenktem Deckel (Fig. 1) den Preßbereich gegen die Hochfrequenzstrahlung abschirmen. Die Schürzen 100 schließen den Spalt zwischen der Auflagefläche 4 des Pressentisches 2 und der Deckelunterseite.During the pressing process, the high-frequency heating is switched on, so that the glue located between the woods 3 hardens rapidly. In order that the radiation generated during high-frequency heating does not escape to the outside, aprons 100 are attached to the edge of the lid ( Fig. 1 to 4 ), which with lowered lid ( Fig. 1 ) Shield the press area against the high frequency radiation. The skirts 100 close the gap between the support surface 4 of the press table 2 and the lid bottom.

Nach Beendigung dieses Preßvorganges wird der Druck im Schlauch 13 verringert und der Deckel 8 mittels des Hydromotors 58 und der Spindeln 56, 57 vom Pressentisch 2 abgehoben. Gleichzeitig mit dem Anheben des Deckels 8 oder hinterher werden die Anschlaglineale 6 so weit zurückgefahren, daß mit dem Schieber 95 die verpreßte Platte vom Pressentisch 2 geschoben werden kann. Zweckmäßig wird die verpreßte Platte durch das nachfolgend auf den Pressentisch 2 geschobene Holzpaket vom Pressentisch geschoben.After completion of this pressing process, the pressure in the tube 13 is reduced and the lid 8 lifted by means of the hydraulic motor 58 and the spindles 56, 57 from the press table 2. Simultaneously with the lifting of the lid 8 or afterwards the stop rulers 6 are moved back so far that with the slider 95, the compressed plate from the press table 2 can be pushed. Appropriately, the compressed plate is pushed by the subsequently pushed onto the press table 2 wood package from the press table.

Je nach Höhe der lamellenförmigen Hölzer 3 werden unterschiedlich hohe Anschlaglineale eingesetzt. Da sie mit ihren Schwertern 27 lediglich in die Schlitten 28, 29 des Antriebsrahmens gesteckt sind, ist ein Austausch der Anschlaglineale 6 einfach und schnell möglich. Um diesen Austausch zu erleichtern, ist für die Anschlaglineale 6 eine Hubvorrichtung 88 vorgesehen (Fig. 10 und 11). Sie hat einen Hubzylinder 89, vorzugsweise einen Pneumatikzylinder, der an einem Längsträger 90 gehalten ist, der an der Unterseite des Pressentisches 2 befestigt ist. Die (nicht dargestellte) Kolbenstange dieses Hubzylinders 89 greift beim Ausfahren an der Unterseite der Schwerter 27 der Anschlaglineale 6 an, wodurch diese in eine Abnahmestellung angehoben werden (Fig. 11). Auf diese Weise ist ein einfacher und problemloser Austausch der Anschlaglineale 6 möglich.Depending on the height of the lamellar woods 3 differently high stop rulers are used. Since they are stuck with their swords 27 only in the carriage 28, 29 of the drive frame, an exchange of the stop rulers 6 is easy and fast. To facilitate this exchange, a lifting device 88 is provided for the stop rulers 6 ( Fig. 10 and 11 ). It has a lifting cylinder 89, preferably a pneumatic cylinder, which is held on a longitudinal member 90 which is fixed to the underside of the press table 2. The (not shown) piston rod of this lifting cylinder 89 engages on extension at the bottom of the swords 27 of the stop ruler 6, whereby they are raised to a removal position ( Fig. 11 ). In this way, a simple and easy replacement of the stop rulers 6 is possible.

Bei einem Produktwechsel können somit die Anschlaglineale 6 einfach gewechselt werden. Auch der Preßdruck und der Hochfrequenzgenerator der Hochfrequenzheizung lassen sich auf das jeweilige Produkt einfach einstellen.In a product change thus the stop rulers 6 can be easily changed. Also, the pressing pressure and the high-frequency generator of the high-frequency heating can be easily adjusted to the particular product.

Die Druckleisten 9 können abweichend vom dargestellten Ausführungsbeispiel auch aus zwei oder mehr hintereinander liegenden Leistenstücken bestehen, die unmittelbar aneinanderliegen.Deviating from the illustrated embodiment, the pressure strips 9 can also consist of two or more strip pieces lying one behind the other, which lie directly against each other.

Vorteilhaft werden die Anschlaglineale 6 und der Deckel 8 so weit bewegt, bis der Druck in den Schläuchen 13, 76 einen vorgegebenen Wert erreicht. Dieser Druck des Druckmediums in den Schläuchen 13, 76 kann einfach überwacht werden. Sobald der Druck erreicht ist, wird die Verstellbewegung beendet, so daß die Anschlaglineale 6 und der Deckel 8 in der jeweiligen Lage stehen bleiben.The stop rulers 6 and the cover 8 are advantageously moved until the pressure in the hoses 13, 76 reaches a predetermined value. This pressure of the pressure medium in the hoses 13, 76 can be easily monitored. As soon as the pressure is reached, the adjusting movement is ended, so that the stop rulers 6 and the cover 8 remain in the respective position.

Es ist auch möglich, die Verstellung der Anschlaglineale 6 und/oder des Deckels 8 zeit- oder wegabhängig zu steuern.It is also possible to control the adjustment of the stop rulers 6 and / or the cover 8 time-dependent or path-dependent.
