Abstract

A device for marking the height above the floor of the edges of articles of clothing in which a force accumulator is charged and released upon actuation of a cloth-pressing lever which drives a pin into the cloth from a pin magazine.

Description

Die Erfindung betrifft eine Vorrichtung zur Markierung der Höhe von Kleidungsstückrändern über dem Boden gemäss Oberbegriff des Anspruchs 1. Eine derartige Vorrichtung ist aus der US-A Nr. 2659147 bekannt.The invention relates to a device for marking the height of garment edges above the floor according to the preamble of claim 1. Such a device is known from US-A No. 2659147.

Eine weitere Vorrichtung ist aus der DE-B Nr. 2538751 bekannt, wobei zur Markierung Fadenmaterial dient. Dieses wird von einer Fadenrolle abgezogen, durchläuft eine Bogennadel und wird durch Betätigen einer Handhabe mittels der Bogennadel nach Einklemmen des Kleidungsstückrandes in den Beugeschlitz von der Bogennadel durch den Stoff gezogen und abgeschnitten. Der doppelarmige Stoffandrückhebel steht unter Federbelastung, wodurch der untere Hebelarm ständig gegen eine Steuerscheibe gedrückt wird. Diese ist fest mit der Handhabeverbunden, so dass nach Drehen der Handhabe der Stoffandrückhebel verschwenkt. Ferner besitzt die Vorrichtung eine aus Klemmbolzen und Klemmanschlag bestehende Fadenklemmeinrichtung, die dafür sorgt, dass das Fadenstück im Stoff verbleibt. Diese Vorrichtung ist aufwendig in ihrem Aufbau. Ferner müssen stets Nadel plus Fadenmaterial durch den Stoff geführt werden, was sich insbesondere bei dünnen, dichtgewebten Stoffen als nachteilig erweist. Ausserdem hängt die Bogennadelgeschwindigkeit davon ab, wie schnell die Handhabe betätigt wird.Another device is known from DE-B No. 2538751, thread material being used for marking. This is pulled off a thread roll, passes through a bow needle and is pulled by the bow needle through the fabric and cut off by actuating a handle by means of the bow needle after clamping the edge of the garment into the flex slot. The double-armed fabric pressure lever is spring-loaded, which means that the lower lever arm is constantly pressed against a control disc. This is firmly connected to the handle so that after turning the handle the fabric pressure lever pivots. Furthermore, the device has a thread clamping device consisting of a clamping bolt and a clamping stop, which ensures that the piece of thread remains in the fabric. This device is complex in its construction. Furthermore, the needle and thread material must always be passed through the fabric, which proves to be disadvantageous, particularly in the case of thin, densely woven fabrics. In addition, the bow needle speed depends on how quickly the handle is operated.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der vorausgesetzten Gattung in herstellungstechnisch einfacher Weise so auszugestalten, dass bei schonender Markierung der Höhe von Kleidungsstückrändern über dem Boden die Nadelgeschwindigkeit stets geichbleibend ist.The object of the invention is based on the object of designing a device of the required type in a manner that is simple to manufacture in such a way that, with gentle marking of the height of the edges of the garment above the floor, the needle speed is always constant.

Gelöst wird diese Aufgabe durch den kennzeichnenden Teil des Anspruchs 1.This object is achieved by the characterizing part of claim 1.

Zufolge derartiger Ausgestaltung ist eine gattungsgemässe Vorrichtung von erhöhtem Gebrauchswert angegeben Die Markierung erfolgt nun sehr schonend, da ausschliesslich eine dünne Nadel durch den Stoff zu stecken ist. Da dieses kraftspeicherbetätigbar vornehmbar ist, erfolgt das Durchstecken der Nadeln stets mit gleicher Geschwindigkeit, und zwar nach vorangegangener Auslösebetätigung, sei es durch Fuss- oder Handbeaufschlagung. Die Grösse des Kraftspeichers kann einstellbar sein. Die Vorrichtung lässt sich in ihrem Aufbau einfach gestalten, indem zum bereits vorhandenen Stoffbeugerlängskanal der Nadelmagazinschaftvorgesehen wird. Die jeweils in den Längskanal eintretende Nadel des Nadelmagazins wird dann durch den Fadeneinschubstössel zwangsläufig durch den im Beugeschlitz vom Stoffandrückhebel fixierten Stoff gesteckt.As a result of such a design, a generic device of increased utility value is specified. The marking is now carried out very gently, since only a thin needle is to be inserted through the fabric. Since this can be actuated by the power store, the needles are always pushed through at the same speed, after the previous actuation, either by foot or by hand. The size of the energy store can be adjustable. The construction of the device can be made simple by providing the needle magazine shaft to the existing longitudinal flexion channel. The needle of the needle magazine entering the longitudinal channel is then inevitably inserted through the thread insertion plunger through the fabric fixed in the flex slot by the fabric pressure lever.

Die Vorrichtung zeichnet sich durch einen sich bei der Einschwenkbewegung des Andrückhebels aufladenen Kraftspeicher aus. Das bedeutet, dass in der Grundstellung der Vorrichtung der Kraftspeicher weitgehend entlastet ist. Erst durch Auslösebetätigung und dem dabei erfolgenden Einschwenken des Andrückhebels wird synchron derThe device is characterized by an energy accumulator that is charged during the pivoting-in movement of the pressure lever. This means that the energy storage is largely relieved in the basic position of the device. Only when the trigger is actuated and the pressure lever swings in is the synchronized

Kraftspeicher aufgeladen, der anschliessend schlagartig den Einschubstössel verschiebt.Lift mechanism loaded, which then suddenly shifts the slide-in ram.

Es kann der Nadeleinschubstössel an einem mit einer Freigabestufe ausgebildeten, vom Kraftspeicher beaufschlagten Schlitten sitzen. Erst wenn der Kraftspeicher genügend aufgeladen ist, lässt die Freigabestufe eine Verlagerung des Schlittens zu. Auf diese Weise ist ausschliesslich mit mechanischen Mitteln stets die schlagartig bedingte Vorwärtsbewegung des Nadeleinschubstössels erzielt.The needle insertion plunger can be seated on a slide designed with a release stage and acted upon by the energy accumulator. Only when the energy accumulator is sufficiently charged does the release level permit the carriage to be moved. In this way, the sudden forward movement of the needle insertion plunger is always achieved exclusively with mechanical means.

Ferner kann der handhebelbetätigbare Andrückhebel mit einem entgegen Federbelastung verlagerbaren und den Kraftspeicher aufladenden Übertragungsschlitten gekuppelt sein, welcher über eine Steuerkurve den Schlitten des Einschubstössels in die rückwärts liegende Grundstellung zurücksteuert. Die Vorrichtung kehrt daher nach Handhebelbetätigung stets in ihre Ausgangsstellung zurück.Furthermore, the pressure lever which can be actuated by hand lever can be coupled to a transmission slide which can be displaced counter to spring loading and which charges the energy accumulator and which controls the slide of the slide-in plunger back into the rearward basic position via a control cam. The device therefore always returns to its starting position after actuation of the hand lever.

Weiterhin erweist es sich als vorteilhaft, wenn der Übertragungsschlitten einen Mitnehmer zur Verlagerung eines in Sperrichtung federbelasteten Auslöseschiebers besitzt. Letzterer arbeitet mit der Freigabestufe des Nadeleinschubstössels zusammen. Erst wenn durch den Übertragungsschlitten über dessen Mitnehmer der Auslöseschieber genügend weit bewegt wird, kann der dann bereits kraftspeicherbelastete Nadeleinschubstössel vorschnellen.Furthermore, it proves to be advantageous if the transmission carriage has a driver for displacing a release slide which is spring-loaded in the blocking direction. The latter works together with the release level of the needle insertion ram. Only when the trigger slide is moved sufficiently far by the transfer carriage via its driver can the needle insertion plunger, which is then already loaded with energy storage, advance.

Eine sichere Führung erhalten die Nadeln dadurch, wenn der Nadelmagazinschacht in der Magazin-Boden- und -Deckenfläche eine Rinne besitzt zur Aufnahme der Nadelköpfe.The needles are securely guided when the needle magazine slot has a groove in the bottom and top of the magazine to accommodate the needle heads.

Eine abgewandelte Variante der Vorrichtung zeichnet sich durch zwei rechtwinklig zueinander stehende Gehäuseschenkel aus, von denen der eine den Nadelmagazinschacht und der andere den Kraftspeicher und Nadeleinschubstössel enthalten. Der Aufbau der Vorrichtung lässt sich dadurch räumlich kleiner und übersichtlicher gestalten. Sodann ergeben sich fertigungs- und führungstechnische Vorteile.A modified variant of the device is characterized by two housing legs which are at right angles to one another, one of which contains the needle magazine shaft and the other of which contains the energy accumulator and needle insert plunger. The structure of the device can thus be made spatially smaller and clearer. Then there are manufacturing and management advantages.

Dabei ist es günstig, dass der aus einer Zugfeder bestehende, vom Nadeleinschubstössel ausgehende und parallel zu diesem liegende Kraftspeicher mit seinem Ende an einem im Eckbereich der Schenkel gelagerten Zentralhebel angreift, welcher mit dem Andrückhebel gekuppelt ist, in seiner Schwenkendstellung einen Sperrhebel für den Nadeleinschubstössel auslöst und an welchem eine Rückholzugfeder angreift und welcher einen Rückdrückanschlag für den Nadeleinschubstössel besitzt. Der Zentralhebel erfüllt eine Mehrfachfunktion. Einerseits stellt er das Teil dar, an welchem der Stoffandrückhebel angreift. Andererseits lädt er bei seiner Verlagerung den Kraftspeicher auf. Darüber hinaus dient er noch zur Steuerung des Sperrhebels. Die besondere Ausrichtung des Kraftspeichers und Anordnung desselben zum Nadeleinschubstössel führt zu dem Vorteil einer grossen Ausstossgeschwindigkeit, so dass auch dickere Stoffe problemlos markiert werden können.It is favorable that the force accumulator, consisting of a tension spring, starting from the needle insertion plunger and lying parallel to it, engages with its end on a central lever mounted in the corner region of the leg, which is coupled to the pressure lever, in its pivoted end position triggers a locking lever for the needle insertion plunger and which is engaged by a return spring and which has a push-back stop for the needle insertion plunger. The central lever fulfills a multiple function. On the one hand, it represents the part on which the fabric pressure lever engages. On the other hand, it reloads the energy accumulator when it is relocated. In addition, it also serves to control the locking lever. The special alignment of the energy accumulator and the arrangement of the same with the needle insertion ram leads to the advantage of a high ejection speed, so that even thicker substances can be marked without problems.

Räumliche Vorteile bringt es, dass die Kraftspeicherfeder und die Rückholzugfeder parallel zueinander verlaufen. Nach erfolgter Auslösung des Nadeleinschubstössels bringt die Rückholzugfeder stets die Vorrichtung in die Grundstellung zurück.There are spatial advantages in that the energy storage spring and the return spring are parallel to each other other run. After the needle insertion plunger has been triggered, the return spring always returns the device to the basic position.

Um das Beschicken des Nadelmagazinschachtes einfach vornehmen zu können, ist der den Nadelmagazinschacht besitzende Gehäuseschenkel mit einer Verschlussklappe ausgestaltet, die mit dem Zuführschieber gekuppelt ist, dessen Feder von einem längs des anderen Gehäuseschenkels umgelegten Federzuges gebildet ist. Der demzufolge lang bemessbare und einen gleichmässigen Anpressdruckauf die Nadeln ausübende Federzug belastet somit die Verschlussklappe noch in Schliessrichtung.In order to be able to easily load the needle magazine shaft, the housing leg having the needle magazine shaft is designed with a closure flap which is coupled to the feed slide, the spring of which is formed by a spring tension which is folded along the other housing leg. As a result, the spring tension, which can be measured for a long time and exerts a uniform contact pressure on the needles, still loads the closure flap in the closing direction.

Eine gute Führung erhalten die Nadeln dadurch, dass der Nadelmagazinschacht von einer wegklappbaren Leiste, die nur einen Teilbereich des Schachtes abdeckt, verschlossen ist, welche Leiste über die Magazinschachtlänge mit einer Stufe vor der Übergangsstelle zwischen Nadelkopf und Nadelschaft liegt. Somit erhalten die Nadeln eine Lagenfixierung in zwei senkrecht zueinander liegenden Richtungen.The needles are given good guidance by the fact that the needle magazine shaft is closed by a fold-away bar that only covers a partial area of the shaft, which bar lies one step ahead of the transition point between the needle head and the needle shaft over the length of the magazine shaft. The needles are thus fixed in two directions perpendicular to each other.

Um unterschiedlich dicke Stoffe mit der Vorrichtung gut markieren zu können, ist der Stoffbeuger um eine Achse drehbar angeordnet und mit unterschiedlich tiefen Einschnitten versehen.In order to be able to mark materials of different thicknesses well with the device, the fabric flexor is arranged rotatable about an axis and provided with incisions of different depths.

Durch Zusammenfassung der für die Vorrichtung geeigneten Nadeln zu einem Nadelmagazin derart, dass die Nadeln kopfseitig zu einer Magazinreihe mit Solltrennstellen zusammengefasst sind, ist gewährleistet, dass bei leichter Beschikkung einer entsprechenden Vorrichtung stets Nadel für Nadel sicher und automatisch ohne Verlustmaterial durch den Kleidungsstückrand gesteckt werden kann. Bei einer Beschickung der Vorrichtung kann eine grössere Anzahl von Nadeln als eine Einheit zugegeben werden, und zwar als zusammenhängende Magazinreihe. Das Ablösen der jeweiligen in den Kleidungsstückrand einzustekkenden Nadel erfolgt dann von der Vorrichtung selbst. Die kopfseitigen Solltrennstellen sind so beschaffen, dass bei der üblichen Handhabung der Magazinreihe keine Trennung herbeigeführt wird. Dies geschieht ausschliesslich durch die Vorrichtung. Die Trennung erfolgt abfallfrei. Grate an der Trennstelle beeinträchtigen den Durchtritt durch den Stoff nicht.By combining the needles suitable for the device into a needle magazine in such a way that the needles are combined at the head to form a magazine row with predetermined separating points, it is ensured that with a light loading of a corresponding device, needle by needle can always be inserted safely and automatically through the edge of the garment without any loss material . When loading the device, a larger number of needles can be added as a unit, namely as a continuous row of magazines. The device itself then removes the respective needle to be inserted into the edge of the garment. The predetermined separation points on the head side are designed in such a way that no separation is brought about in the usual handling of the magazine row. This is done exclusively by the device. The separation is waste-free. Burrs at the separation point do not affect the passage through the fabric.

Die in den Fig. 1 bis 9 dargestellte Vorrichtung besitzt eine Fussplatte 1, von welcher eine vertikal gerichtete Säule 2 ausgeht. Auf dieser ist ein mittels eines Spannknebels 3 feststellbarer Tragarm 4 geführt, welcher die untere Ecke einer mit parallelem Abstand zueinander liegenden Bodenplatte 5 und Deckplatte 6 umgreift.The device shown in FIGS. 1 to 9 has a base plate 1, from which a vertically directed column 2 extends. A support arm 4, which can be locked by means of a clamping toggle 3, is guided on this and engages around the lower corner of a base plate 5 and cover plate 6 which are parallel to one another.

In der Bodenplatte 5 ist ein horizontal verlaufender, zur einen Seite der Bodenplatte hin offener Längskanal 7 vorgesehen. Dieser kreuzt einen vertikal gerichteten Beugeschlitz 8 des von einem Vorsprung der Bodenplatte 5 gebildeten Stoffbeugers 9. Wie insbesondere aus Fig. 7 und 8 ersichtlich ist, besitzt der Beugeschlitz 8 eine geringere Tiefe als der Längskanal 7. Die Bodenplatte 5 ist im Bereich des Stoffbeugers 9 verdickt ausgebildet, so dass der Längskanal 7 in diesem Bereich rinnenförmig gestaltet ist.Provided in the base plate 5 is a horizontally extending longitudinal channel 7 which is open on one side of the base plate. This crosses a vertically directed flexion slot 8 of the fabric flexor 9 formed by a projection of the base plate 5. As can be seen in particular from FIGS. 7 and 8, the flexion slot 8 has a smaller depth than the longitudinal channel 7. The base plate 5 is in the region of the fabric flexor 9 formed thickened, so that the longitudinal channel 7 is channel-shaped in this area.

In Verlängerung des Längskanales 7 führt sich ein Nadeleinschubstössel 10, der mit einem horizontal verschieblichen Schlitten 11 festverbunden ist. Zur Führung des Schlittens 11 dienen zwei von der Bodenplatte 5 ausgehende Führungszapfen 12, die Längsschlitze des Schlittens 11 durchgreifen. An der dem Nadeleinschubstössel 10 gegenüberliegenden Seite formt der Schlitten 11 eine Freigabestufe 13, vor die das obere Ende 14' eines auf Stehbolzen 15 vertikal beweglichen Auslöseschiebers 14 tritt. Die Stehbolzen 15 sind ebenfalls in der Bodenplatte 5 verankert und tauchen in Längsschlitze 16, 17 des Auslöseschiebers 14 ein. Der Längsschlitz 17 ist länger bemessen und nimmt eine Druckfeder 18 auf, die den Auslöseschieber 14 in Sperrichtung belastet.In the extension of the longitudinal channel 7 there is a needle insertion ram 10, which is firmly connected to a horizontally displaceable slide 11. Two guide pins 12, which extend from the base plate 5 and pass through the longitudinal slots in the slide 11, are used to guide the slide 11. On the side opposite the needle insertion plunger 10, the slide 11 forms a release stage 13, in front of which the upper end 14 'of a trigger slide 14 which is vertically movable on the stud bolt 15 occurs. The stud bolts 15 are also anchored in the base plate 5 and plunge into longitudinal slots 16, 17 of the trigger slide 14. The longitudinal slot 17 is longer and receives a compression spring 18 which loads the trigger slide 14 in the reverse direction.

Ferner gehen von der Bodenplatte 5 Stehbolzen 19 aus, die Vertikalschlitze 20 und 21 eines vertikal geführten Übertragungsschlittens 22 durchsetzen. In dem Vertikalschlitz 21 ist eine Druckfeder 60 untergebracht, die den Übertragungsschlitten in Aufwärtsrichtung beaufschlagt. An seinem oberen Ende ist der Übertragungsschlitten 22 mit einer Rolle 23 ausgestattet, die den Schlitten 11 über eine Steuerkurve 24 in die rückwärts liegende Grundstellung gemäss Fig. 3 zurücksteuert. 1 n dieser Position befindet sich das obere Ende 14' des Auslöseschiebers 14 vor der Freigabestufe 13 des Schlittens 11.Furthermore, stand bolts 19 extend from the base plate 5 and penetrate the vertical slots 20 and 21 of a vertically guided transmission slide 22. In the vertical slot 21, a compression spring 60 is accommodated, which acts on the transmission carriage in the upward direction. At its upper end, the transmission carriage 22 is equipped with a roller 23 which controls the carriage 11 back into the rearward basic position according to FIG. 3 via a control cam 24. In this position, the upper end 14 ′ of the trigger slide 14 is in front of the release stage 13 of the slide 11.

Am rückwärtigen Ende des Schlittens 11 greift das eine Ende 25' einer als Blattfeder ausgebildeten Kraftspeicherfeder 25 an. Das andere Ende 25" der Kraftspeicherfeder 25 findet Abstützung an einem Querzapfen 26 eines Hebelarmes 27' eines winkelförmig gestalteten Übertragungshebels 27, der im Winkelscheitel um einen bodenplattenseitigen Lagerzapfen 28 schwenkbar ist. Der Übertragungshebel 27 greift mit seinem längeren Hebelarm 27" in eine randseitige Ausnehmung 29 des Übertragungsschlittens 22 ein.At the rear end of the slide 11, one end 25 ′ engages an energy storage spring 25 designed as a leaf spring. The other end 25 "of the energy storage spring 25 is supported on a cross pin 26 of a lever arm 27 'of an angularly shaped transmission lever 27 which can be pivoted in the apex around a bearing plate 28 on the base plate side. The transmission lever 27 engages with its longer lever arm 27" in an edge-side recess 29 of the transfer carriage 22.

Auf der der Ausnehmung 29 gegenüberliegenden Seite ist der Übertragungsschlitten 22 mit einem Mitnehmer 30 bestückt. In die Bewegungsbahn desselben ragt ein mit Abstand dazu liegender Mitnehmervorsprung 31 des Auslöseschiebers 14.On the side opposite the recess 29, the transmission carriage 22 is equipped with a driver 30. A driver projection 31 of the trigger slide 14, which lies at a distance therefrom, projects into the movement path thereof.

Unterhalb des Mitnehmers 30 befindet sich eine weitere randseitige Ausnehmung 32. In diese greift das eine Ende 33' eines doppelarmigen, um den ortsfesten Lagerzapfen 34 der Bodenplatte 5 schwenkbaren Steuerhebels 33. Das andere Ende 33" des Steuerhebels 33 taucht in eine fensterförmige Öffnung 35 eines winkelförmig gestalteten Stoffandrückhebels 36 ein. Die fensterförmige Öffnung 35 befindet sich in dem kürzeren, unteren Winkelschenkel 36', welcher endseitig mittels eines Lagerbolzens 37 schwenkbar an einem vertikal zur Bodenplatte 5 gerichteten Ausleger 38 angeordnet ist. Der Winkelschenkel 36' wird umgriffen von einem gabelförmigen Übertragungsglied 39. Ein Kupplungszapfen 40 durchsetzt das Übertragungsglied 39 und den Winkelschenkel 36' des Stoffandrückhebels 36. An dem Übertragungsglied 39 greift die Seele 41' eines Bowdenzuges 41 an. Letzterer führt zu einem Handhebel 42. Wird dieser betätigt, verschwenkt der Stoffandrückhebel 36, wobei sein längerer Winkelschenkel 36" mit seinem Eintauchende 36'" in den Beugeschlitz 8 tritt. In dem Eintauchende 36"' befindet sich eine endseitig offene Ausnehmung 43, die in dieser Stellung (vgl. Fig. 5) mit dem Längskanal 7 fluchtet.Below the driver 30 there is a further recess 32 on the edge. One end 33 ′ of a double-armed control lever 33 that can be pivoted about the fixed bearing journal 34 of the base plate 5 engages in this. The other end 33 ″ of the control lever 33 dips into a window-shaped opening 35 angled fabric pressure lever 36. The window-shaped opening 35 is located in the shorter, lower angle leg 36 ', which is pivotally arranged at the end by means of a bearing pin 37 on a bracket 38 oriented vertically to the base plate 5. The angle leg 36' is encompassed by a fork-shaped transmission member 39. A coupling pin 40 passes through the transmission member 39 and the angle leg 36 'of the fabric pressure lever 36. The soul 41' of a Bowden cable 41 engages on the transmission member 39. The latter leads to a hand lever 42. If this is actuated, the fabric pressure lever 36 pivots, with its longer angle leg 36 "with his Immersing 36 '"enters the flexion slot 8. In the immersion end 36 '' there is a recess 43 which is open at the end and which, in this position (cf. FIG. 5), is aligned with the longitudinal channel 7.

Quer zum Längskanal 7, in dessen Verlängerung der Nadeleinschubstössel 10 geführt ist, erstreckt sich ein Nadelmagazinschacht 44. Letzterer ist gebildet von der Bodenplatte 5 und einer auf dieser befestigten Schachtwand 45. Der Nadelmagazinschacht 44 besitzt in der Magazin-Boden- und -Deckenfläche eine Rinne 46 zur Aufnahme der Nadelköpfe 47 eines Nadelmagazins N.A needle magazine shaft 44 extends transversely to the longitudinal channel 7, in the extension of which the needle insertion plunger 10 is guided. The latter is formed by the base plate 5 and a shaft wall 45 fastened thereon. The needle magazine shaft 44 has a groove in the magazine bottom and top surface 46 for receiving the needle heads 47 of a needle magazine N.

Die Nadelköpfe 47 der Nadeln 48 sind gemäss der ersten Ausführungsform (vgl. Fig. 10 bis 13) zu einer Magazinreihe zusammengefasst und besitzen eine mittlere, zwei endseitige Grundplatten 49 und 50 verbindende Ringnut 51. Die Grundplatten 49, 50 sind zylindrisch gestaltet, wobei die Grundplatten dieser Zylinder unter Bildung einer Solltrennstelle 52 tangential zueinanderliegend verbunden sind. Diese Solltrennstellen 52 werden beispielsweise beim Spritzen der aus Kunststoff bestehenden Nadelköpfe 47 erzeugt.According to the first embodiment (cf. FIGS. 10 to 13), the needle heads 47 of the needles 48 are combined to form a magazine row and have a central annular groove 51 connecting two base plates 49 and 50 at the ends. The base plates 49, 50 are cylindrical, the Base plates of these cylinders are connected tangentially to form a predetermined separation point 52. These predetermined separation points 52 are produced, for example, when the needle heads 47 made of plastic are injection molded.

Die Nadeln 48 sind mit einem verdickt ausgebildeten Nadelende 48' versehen, welches von der einen Grundplatte 50 beim Spritzvorgang umkleidet wird.The needles 48 are provided with a thickened needle end 48 ', which is covered by the one base plate 50 during the injection molding process.

Bei der in Fig. 14 und 15 dargestellten zweiten Ausführungsform des Nadelmagazins N' sind die Nadelköpfe entsprechend der vorangegangenen Ausführungsform ausgebildet. Gleiche Teile tragen daher gleiche Bezugszeichen. Abweichend von der vorbeschriebenen Ausführungsform ist jedoch die Breite der Solltrennstellen 52' schmaler als die Dicke der Grundplatten 49, 50 (vgl. insbesondere Fig. 14). Diese Solltrennstellen können ebenfalls beim Spritzen der aus Kunststoff bestehenden Nadelköpfe 47 erzeugt werden.In the second embodiment of the needle magazine N 'shown in FIGS. 14 and 15, the needle heads are designed in accordance with the previous embodiment. The same parts therefore have the same reference numerals. Deviating from the above-described embodiment, however, the width of the predetermined separation points 52 'is narrower than the thickness of the base plates 49, 50 (cf. in particular FIG. 14). These predetermined separation points can also be generated when the needle heads 47 made of plastic are injection molded.

Die Fig. 16 und 17 zeigen ein Nadelmagazin N" mit Nadelköpfen 47', deren Grundplatten 49', 50' durch zwei an gegenüberliegenden Seiten angeordnete, sekantenartig zum Nadelkopf 47' liegende Vertiefungen 57 gebildet sind. Der Grund 57' dieser Vertiefungen ist flach. Verbunden sind die Grundplatten 49', 50' untereinander durch Solltrennstellen 52" derart, dass diese symmetrisch zwischen den Vertiefungen 57 liegen. Ebenfalls sind bei dieser Variante die Solltrennstellen 52" schmaler als die Dicke der Grundplatten 49', 50'.16 and 17 show a needle magazine N "with needle heads 47 ', the base plates 49', 50 'by two on opposite sides arranged, secant-like recesses 57 to the needle head 47 'are formed. The bottom 57 'of these depressions is flat. The base plates 49 ', 50' are connected to one another by predetermined separation points 52 "in such a way that they lie symmetrically between the depressions 57. Likewise, in this variant, the predetermined separation points 52" are narrower than the thickness of the base plates 49 ', 50'.

Ein aus mehreren Nadeln bestehendes Nadelmagazin N kann in den Nadelmagzinschacht 44 eingestecktwerden, wenn vorher der Zuführschieber 53 aus der Rinne 46 herausgezogen wird. Beim Einsetzen des Nadelmagazins N gelangen die Nadelköpfe 47 in die Rinne 46, während die Nadeln 48 von der Schachtwand 45 überfangen werden. Danach ist der Zuführschieber 53 in die Rinne 46 einzustecken. Letzterer steht unter der Belastung eines elastischen Zuggliedes 54, wodurch das Nadelmagazin N in Richtung des Längskanales 7 bewegt wird. Der Nadelkopf 47 der obersten Nadel wird dann über eine Schrägfläche 55 in den Längskanal 7 gelenkt, so dass sich der Nadelkopf 47 dicht vor dem Nadeleinschubstössel befindet (vgl. Fig. 7).A needle magazine N consisting of a plurality of needles can be inserted into the needle magazine shaft 44 if the feed slide 53 is previously pulled out of the groove 46. When the needle magazine N is inserted, the needle heads 47 enter the groove 46, while the needles 48 are overlaid by the shaft wall 45. Then the feed slide 53 is to be inserted into the channel 46. The latter is under the load of an elastic tension member 54, whereby the needle magazine N is moved in the direction of the longitudinal channel 7. The needle head 47 of the uppermost needle is then directed into the longitudinal channel 7 via an inclined surface 55, so that the needle head 47 is located close to the needle insertion plunger (cf. FIG. 7).

Soll ein Kleidungsstückrand 56 mit Nadeln markiert werden, so ist vorerst die entsprechende Höhenlage durch Verlagern des Tragarms 4 mittels des Spannknebels 3 einzustellen. Danach ist der Kleidungsstückrand 56 in den Bereich des Stoffbeugers 9 zu bringen. Anschliessend wird durch Betätigen des Handhebels 42 über den Bowdenzug 41 das Übertragungsstück 39 aufwärts bewegt, welches mittels des Kupplungszapfens 40 den Stoffandrückhebel 36 verschwenkt. Der in die fensterförmige Öffnung 35 eintauchende Steuerhebel 33 wird nun mitgeschleppt. Dieser verlagert den Übertragungsschlitten 22 in Abwärtsrichtung. Synchron hierzu wird der Übertragungshebel 27 verschwenkt, der seinerseits die Kraftspeicherfeder 25 auflädt. Nach entsprechend weiter Verlagerung des Übertragungsschlittens 22 beaufschlagt dessen Mitnehmer 30 den Mitnehmervorsprung 31 des Auslöseschiebers 14, dessen oberes Ende 14' sich von der Freigabestufe 13 des Schlittens 11 entfernt. Die aufgeladene Kraftspeicherfeder 25 kann nun wirksam werden, die ihrerseits den Schlitten 11 mit dem daran befestigten Nadeleinschubstössel 11 vorschnellen lässt. Bei diesem Vorgang wird der von dem Stoffandrückhebel 36 in den Beugeschlitz 8 eingeklemmte Kleidungsstückrand 56 von der Nadel 48 unter Bildung einer Schlaufe durchstochen (vgl. Fig. 7 bis 9). Das Durchstechen des Stoffes geschieht stets mit gleicher Kraft und Geschwindigkeit.If a garment edge 56 is to be marked with needles, the corresponding height must first be set by moving the support arm 4 by means of the tensioning knob 3. Then the garment edge 56 is to be brought into the area of the fabric flexor 9. Subsequently, by actuating the hand lever 42 via the Bowden cable 41, the transmission piece 39 is moved upwards, which swivels the fabric pressure lever 36 by means of the coupling pin 40. The control lever 33 which dips into the window-shaped opening 35 is now dragged along. This shifts the transmission carriage 22 in the downward direction. Synchronously with this, the transmission lever 27 is pivoted, which in turn charges the energy storage spring 25. After a corresponding further displacement of the transmission carriage 22, its driver 30 acts on the driver projection 31 of the trigger slide 14, the upper end 14 'of which is removed from the release stage 13 of the carriage 11. The charged energy storage spring 25 can now take effect, which in turn allows the slide 11 to snap forward with the needle insertion plunger 11 attached to it. In this process, the edge of the garment 56, which is clamped into the flex slot 8 by the fabric pressure lever 36, is pierced by the needle 48 to form a loop (cf. FIGS. 7 to 9). Piercing the fabric is always done with the same force and speed.

Wenn der Handhebel 42 nicht mehr beaufschlagt wird, bringt die Druckfeder 60 den Übertragungsschlitten 22 unter Aufwärtsverlagerung in die Grundstellung zurück, wobei über die Rolle 23 der Schlitten 11 ebenfalls in seine Ausgangsstellung zurückbewegt wird. Gleichfalls kehren der Auslöseschieber 14, der Hebel 27 und der Steuerhebel 33 in die Ausgangsstellung zurück, welch letzterer den Stoffandrückhebel 36 in die Position gemäss Fig. 2verschwenkt. Nun kann die nächste Nadel 48 zwecks Markierung angesetzt werden.When the hand lever 42 is no longer acted upon, the compression spring 60 brings the transfer carriage 22 back into the basic position by upward displacement, the carriage 11 likewise being moved back into its starting position via the roller 23. Likewise, the trigger slide 14, the lever 27 and the control lever 33 return to the starting position, the latter pivoting the fabric pressure lever 36 into the position according to FIG. 2. The next needle 48 can now be attached for the purpose of marking.

Bei jedem Vorschiessen des kraftspeicherbeaufschlagten Fadeneinschubstössels 10 wird die obere, in den Längskanal 7 eintauchende Nadel an der Solltrennstelle 52 von der benachbarten Nadel abgetrennt.Each time the thread insertion ram 10 loaded with energy is advanced, the upper needle, which dips into the longitudinal channel 7, is separated from the adjacent needle at the desired separation point 52.

Die in den Fig. 19 bis 27 dargestellte Vorrichtung besitzt eine von Laufrollen 61 getragene Fussplatte 62. Auf deren Säule 63 ist der mittels eines Spannhebels 64feststellbareTragarm 65 geführt. Letzterer geht von der Deckplatte 66' eines Gehäuses 66 aus. Dieses weist zwei rechtwinklig zueinander stehende Gehäuseschenkel 67, 68 auf, von denen der letztere den Nadelmagazinschacht 69 und der andere den Kraftspeicher 70 und den Nadeleinschubstössel 71 enthalten.The device shown in FIGS. 19 to 27 has a base plate 62 carried by rollers 61. The support arm 65, which can be locked by means of a tensioning lever 64, is guided on its column 63. The latter starts from the cover plate 66 'of a housing 66. This has two housing legs 67, 68 which are at right angles to one another, the latter of which contains the needle magazine shaft 69 and the other the energy store 70 and the needle insertion plunger 71.

Der Nadeleinschubstössel 71 sitzt an einem horizontal verlagerbaren Schlitten 72. Zu seiner Führung dienen die seine Längsschlitze 73 durchsetzenden gehäuseseitigen Führungszapfen 74. Am hinteren Ende des Schlittens 72 greift der von einer Zugfeder gebildete Kraftspeicher 70 an. Das andere Ende des Kraftspeichers führt zu einem im Eckbereich der Schenkel 67, 68 um den Zapfen 75 gelagerten Zentralhebel 76. Bezüglich desselben handelt es sich um einen Winkelhebel, wobei der Kraftspeicher 70 an dem längeren Hebelarm 76' angreift. Jenseits des Angriffspunktes des Kraftspeichers an dem Zentral hebel 76 befindet sich am freien Ende des längeren Hebelarmes 76' ein von einer Rolle 77 gebildeter Rückdrückanschlag, der zufolge Federbelastung gegen einen Steuervorsprung 72' des Schlittens 72 tritt. Unterhalb der Kraftspeicherzugfeder 70 ist eine Rückholzugfeder 78 angeordnet. Deren hinteres Ende ist an einem Stehzapfen 79 des Schenkels 67 festgelegt. Das andere Ende greift dagegen an dem längeren Hebelarm 76' des Zentral hebels 76 an und belastet diesen in Uhrzeigerrichtung.The needle insertion plunger 71 is seated on a horizontally displaceable slide 72. The housing-side guide pins 74 passing through its longitudinal slots 73 serve to guide it. The force accumulator 70 formed by a tension spring acts on the rear end of the slide 72. The other end of the energy accumulator leads to a central lever 76 which is mounted around the pin 75 in the corner region of the legs 67, 68. With regard to the same, it is an angle lever, the energy accumulator 70 engaging the longer lever arm 76 '. Beyond the point of application of the energy accumulator on the central lever 76 is at the free end of the longer lever arm 76 'a return stop formed by a roller 77, which occurs according to spring loading against a control projection 72' of the carriage 72. A return tension spring 78 is arranged below the energy storage tension spring 70. The rear end is fixed to a stud 79 of the leg 67. The other end, on the other hand, engages the longer lever arm 76 'of the central lever 76 and loads it clockwise.

Der kürzere Hebelarm 76" des Zentralhebels 76 bildet die Anlenkstelle 80 für eine längeneinstellbare Zugstange 81.The shorter lever arm 76 "of the central lever 76 forms the articulation point 80 for a length-adjustable pull rod 81.

Ein unterhalb des Schlittens 72 um einen Gelenkzapfen 82 schwenkbarer Sperrhebel 83 liegt in der Grundstellung der Vorrichtung mit einer Sperrschulter 84 vor der Freigabestufe 85 des Schlittens und verhindert somit das Vorschnellen desselben. Der Sperrhebel 83 steht unter der Wirkung einer Zugfeder 86, die den Sperrhebel in Uhrzeigerrichtung belastet und somit die Sperrschulter 84 vor die Freigabestufe 85 bringt. An dem winkelförmig gestalteten Sperrhebel 83 befindet sich am kürzeren Winkelschenkel ein Mitnehmervorsprung 87, der in der Bewegungsbahn eines zentralhebelseitigen Mitnehmers 88 liegt.A locking lever 83 which can be pivoted about a hinge pin 82 below the slide 72 lies in the basic position of the device with a locking shoulder 84 in front of the release level 85 of the slide and thus prevents the latter from rushing forward. The locking lever 83 is under the action of a tension spring 86, which loads the locking lever clockwise and thus brings the locking shoulder 84 in front of the release level 85. On the angled locking lever 83 there is a driver projection 87 on the shorter angle leg, which lies in the path of movement of a driver 88 on the central lever side.

Der Nadeleinschubstössel 71 läuft in dem horizontal verlaufenden Längskanal 89 des Gehäusebodens 90 und liegt quergerichtet zu dem Beugeschlitz 91 des an das Gehäuse 66 angesetzten Stoffbeugers 92.The needle insert ram 71 runs in the horizontally extending longitudinal channel 89 of the housing base 90 and lies transversely to the flexion slot 91 of the fabric flexor 92 attached to the housing 66.

Das untere Ende der Zugstange 81 ist gelenkig mit dem Stoffandrückhebel 93 gekuppelt. Derselbe ist in Winkelform erstellt. Die Lagerstelle befindet sich im Winkelscheitel derart, dass vom vertikalen Gehäuseschenkel 68 ausgehende Laschen 94 von Gelenkzapfen 95 durchsetzt werden. Der kürzere Hebelarm 93' trägt eine Bedienungsstange 96. Der längere Winkelschenkel 93" bildet das Eintauchende 93"' aus, das beim Verschwenken des Stoffandrückhebels mittels der Bedienungsstange 96 in den Beugeschlitz 91 des Stoffbeugers 92 tritt. In dem Eintauchende 93"' befindet sich eine endseitig offene Ausnehmung 97, die in der Arbeitsstellung des Stoffandrückhebels 93 mit dem Längskanal 89 fluchtet.The lower end of the pull rod 81 is articulated to the fabric pressure lever 93. The same is created in an angular form. The bearing is located in the apex such that the verti Kalalen housing leg 68 outgoing tabs 94 are penetrated by pivot pin 95. The shorter lever arm 93 'carries an operating rod 96. The longer angle leg 93 "forms the immersion end 93"' which, when the fabric pressure lever is pivoted, enters the flexing slot 91 of the fabric flexor 92 by means of the operating rod 96. In the immersion end 93 ″ there is a recess 97 which is open at the end and which is aligned with the longitudinal channel 89 in the working position of the fabric pressure lever 93.

Der in den Längskanal 89 mündende Nadelmagazinschacht 69 besitzt im Gehäuseboden 90 eine vertikal ausgerichtete Rinne 98 zur Aufnahme der Nadelköpfe 47" eines Nadelmagazins N"'. Die von den Nadelköpfen 47" ausgehenden Nadelschäfte werden überfangen von einer Deckplatte 99. Ein an dem Gehäuseschenkel 68 gelagerter Zuführschieber 100 drückt gegen den untersten Nadelkopf des Nadelmagazins N"' und belastet die Nadeln somit in Richtung des Längskanals 89. Zu diesem Zweck greift an dem Zuführschieber 100 ein Federzug 101 an, der um zwei Rollen 102 und 103 des horizontalen Gehäuseschenkels 67 gelegt ist. Das andere Ende dieses Federzuges 101 ist nahe der Rolle 102 befestigt. Die Rollen 102,103 sowie der entsprechende Bereich des Federzuges 101 werden von einer Kappe 104 abgedeckt.The needle magazine shaft 69 opening into the longitudinal channel 89 has a vertically oriented groove 98 in the housing base 90 for receiving the needle heads 47 "of a needle magazine N" '. The needle shafts emanating from the needle heads 47 "are overlaid by a cover plate 99. A feed slide 100 mounted on the housing leg 68 presses against the lowest needle head of the needle magazine N" 'and thus loads the needles in the direction of the longitudinal channel 89 Feed slide 100 to a spring balancer 101, which is placed around two rollers 102 and 103 of the horizontal housing leg 67. The other end of this spring balancer 101 is attached near the roller 102. The rollers 102, 103 and the corresponding area of the spring balancer 101 are covered by a cap 104.

Oberhalb des Einführschiebers 100 ist an dem vertikalen Gehäuseschenkel 68 ein Auslöseschlitten 105 geführt. An letzterem greift ein Lenker 106 an, der seinerseits mit einer den Nadelmagazinschacht 69 überfangenden Verschlussklappe 107 gelenkig verbunden ist. Diese lagert am unteren Ende des Gehäuseschenkels 68 um dessen An--lenklaschen 108 durchsetzende Gelenkzapfen 109. Das der Anlenkstelle gegenüberliegende Ende der Verschlussklappe 107 bildet einen Verschlusshaken 110 aus, der in der Abdeckstellung der Verschlussklappe den oberen Bereich der Deckplatte 66' überfängt.A release slide 105 is guided on the vertical housing leg 68 above the insertion slide 100. A handlebar 106 engages the latter, which in turn is connected in an articulated manner to a closure flap 107 overlapping the needle magazine shaft 69. This rests on the lower end of the housing leg 68 around its hinge pins 109 passing through the link plates 108. The end of the closure flap 107 opposite the articulation point forms a closure hook 110 which, in the closed position of the closure flap, extends over the upper region of the cover plate 66 '.

Am unteren Ende des Gehäuseschenkels 68 lagert ferner eine wegklappbare Leiste 111. Diese deckt nur einen Teilbereich der Rinne 98 des Schachtes ab. An der den Nadeln zugekehrten Seite besitzt die sich über die Magazinschachtlänge erstreckende Leiste 111 eine Stufe 112, die vor der Übergangsstelle zwischen Nadelkopf 47" und Nadelschaft 48 liegt (vgl. Fig. 27). Somit sind die Nadeln in zwei senkrecht zueinander liegenden Ebenen fixiert. Die Leiste 111 steht unter der Belastung einer Druckfeder 113, die sich einerseits an der Leiste und andererseits an dem Lagerzapfen 114 der Leiste abstützt. Somit wird die Leiste 111 in Aufwärtsrichtung belastet. In der Gebrauchsstellung hintergreift ein endseitiger Haken 115 einen vom Gehäuseboden ausgehenden Sperrvorsprung 116. Vorzugsweise kann die Leiste 111 unter der Wirkung einer nicht dargestellten Feder stehen, die bestrebt ist, die Leiste 111 entgegen Uhrzeigerrichtung zu verschwenken, so dass die auf die Nadeln ausgeübte Reibung gering ist. Zum Beschicken des Nadelmagazinschachts ist es nach Verschwenken der Verschlussklappe 107 (siehe Fig. 25) erforderlich, die Leiste 111 in Abwärtsrichtung zu verlagern, damit der Sperrvorsprung 116 das anschliessende Verschwenken der Leiste 111 entgegen Uhrzeigerrichtung zulässt. Mit dem Verschwenken der Verschlussklappe 107 hat der mit dieser über den Lenker 106 gekuppelte Steuerschlitten 105 den Zuführschieber 100 ebenfalls in Abwärtsrichtung verlagert, so dass behinderungsfrei ein Nadelmagazin N"' eingesteckt werden kann. Nach Zurückführen der Leiste 111 und der Verschlussklappe in die Grundstellung ist die Vorrichtung einsatzbereit.At the lower end of the housing leg 68 there is also a bar 111 which can be folded away. It covers only a partial area of the channel 98 of the shaft. On the side facing the needles, the strip 111, which extends over the length of the magazine shaft, has a step 112 which lies in front of the transition point between the needle head 47 "and the needle shaft 48 (cf. FIG. 27). The needles are thus fixed in two mutually perpendicular planes The bar 111 is under the load of a compression spring 113, which is supported on the one hand on the bar and on the other hand on the bearing journal 114 of the bar, thus loading the bar 111 in the upward direction. In the use position, an end hook 115 engages behind a locking projection extending from the housing base 116. The bar 111 can preferably be under the action of a spring, not shown, which tends to pivot the bar 111 counterclockwise so that the friction exerted on the needles is low. To load the needle magazine shaft, it is necessary to pivot the closure flap 107 (see Fig. 25) required, the bar 111 in the downward direction ng to shift, so that the locking projection 116 allows the subsequent pivoting of the bar 111 counterclockwise. When the closure flap 107 is pivoted, the control slide 105, which is coupled to it via the handlebar 106, has also displaced the feed slide 100 in the downward direction, so that a needle magazine N "'can be inserted without hindrance Device ready for use.

Beim Verschwenken des Stoffandrückhebels 93 mittels der Bedienungsstange 96 wird über die Zugstange 81 der Zentralhebel 76 entgegen Uhrzeigerrichtung verschwenkt, unter gleichzeitigem Aufladen der Kraftspeicherzugfeder 70 und der Rückholzugfeder 78. Der Schlitten 72 kann in der Anfangsphase noch nicht vorschnellen. Dies ist erst dann möglich, wenn der Mitnehmer 88 des Zentralhebels 76 den Mitnehmervorsprung 87 des Sperrhebels 83 so weit verlagert, dass dessen Sperrschulter 84 sich von der Freigabestufe 85 des Schlittens 72 entfernt (siehe Fig. 22). Dann kann zufolge der aufgeladenen Kraftspeicherzugfeder 70 der Schlitten 72 mit dem Nadeleinschubstössef 71 vorschnellen, wobei eine in dem Längskanal 89 befindliche Nadel von den übrigen Nadeln abgetrennt und in einen Kleidungsstückrand hineingebracht wird. Nach Loslassen der Bedienungsstange führt die Rückholzugfeder den Schlitten 72 über den Zentralhebel 76 in die Grundstellung zurück, in welcher die Sperrschulter 84 des Sperrhebels vor die Freigabestufe 85 des Schlittens tritt. Vorzugsweise ist die Kraft der Rückholzugfeder 78 grösser als diejenige der Kraftspeicherzugfeder 70.When the fabric pressure lever 93 is pivoted by means of the operating rod 96, the central lever 76 is pivoted counterclockwise via the pull rod 81, with simultaneous charging of the energy storage tension spring 70 and the return tension spring 78. The carriage 72 cannot yet advance in the initial phase. This is only possible when the driver 88 of the central lever 76 shifts the driver projection 87 of the locking lever 83 so far that its locking shoulder 84 moves away from the release level 85 of the slide 72 (see FIG. 22). Then, due to the charged energy storage tension spring 70, the slide 72 can snap forward with the needle insertion pushes 71, a needle located in the longitudinal channel 89 being separated from the other needles and being brought into a garment edge. After releasing the operating rod, the return spring returns the slide 72 via the central lever 76 to the basic position in which the locking shoulder 84 of the locking lever comes before the release level 85 of the slide. The force of the return tension spring 78 is preferably greater than that of the energy storage tension spring 70.

Das in den Fig. 30 und 31 dargestellte Nadelmagazin N"' besitzt die aus Kunststoff bestehenden zylindrischen Nadelköpfe 47", die durch Stege 52', welche die Solltrennstellen bilden, untereinander verbunden sind. Diese Stege 52' erstrekken sich in der Mittelebene des Nadelmagazins N"'. Bei diesem Nadelmagazin sind sowohl die Nadelköpfe 47" als auch die Nadelschäfte einstückig aus Kunststoff gespritzt.The needle magazine N "'shown in FIGS. 30 and 31 has the cylindrical needle heads 47" which are made of plastic and which are connected to one another by webs 52' which form the desired separation points. These webs 52 'extend in the central plane of the needle magazine N "'. In this needle magazine, both the needle heads 47" and the needle shafts are injection-molded in one piece from plastic.

In Fig. 28 und 29 ist ein abweichend ausgebildeter Stoffbeuger 117 dargestellt. Dieser ist um einen Achszapfen 118 drehbar angeordnet. Auf zwei gegenüberliegenden Seiten ist er mit unterschiedlich tiefen und grossen Einschnitten 119 und 120 versehen derart, dass der Abstand x grösser ist als Abstand y. In den in Fig. 28 und 29 dargestellten Gebrauchsstellung ist der Stoffbeuger 117 auf dünnere Stoffe eingestellt. Sollen dikkere Stoffe mit Nadeln bestückt werden, so ist der Stoffbeuger 117 um 180° zu verdrehen, so dass dann der von dem Einschnitt 120 gebildete Beugeschlitz zum Einsatz gelangt. Anstatt wie dargestellt ist, könnte der Stoffbeuger 117 noch weitere Einschnitte enthalten.28 and 29 a deviatingly configured flexor 117 is shown. This is rotatably arranged about an axle pin 118. On two opposite sides it is provided with incisions 119 and 120 of different depths and sizes such that the distance x is greater than the distance y. In the use position shown in FIGS. 28 and 29, the fabric flexor 117 is set to thinner fabrics. If thicker fabrics are to be fitted with needles, the flexor 117 must be rotated by 180 ° so that the flexing slot formed by the incision 120 is then used. Instead of as shown, the fabric flexor 117 could contain further incisions.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
