Abstract

Heddle comprises an elongated one-piece body (4) with a straight edge (10), a thread eyelet (7) and end eyelets (5), where the width (A) of the body at the end eyelets is up to twice the width (D) at the thread eyelet.

Description

Die Erfindung betrifft eine Weblitze mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a heddle with the features of the preamble of claim 1.

Aus Festigkeitsgründen werden Weblitzen für Hochleistungswebmaschinen üblicherweise aus vergütetem Stahl hergestellt. Diese Litzen werden aus einem Stahlband ausgestanzt. Als Bandbreite zur Herstellung solcher Litzen hat sich für das Stahlband weltweit eine Breite von 5,5 mm bis 6 mm als Standard durchgesetzt. Weil die Litzen wegen der hohen Webgeschwindigkeiten trotz der hohen spezifischen Masse des Stahls möglichst leicht sein sollen, werden entlang der Litzenlängsrichtung möglichst große Anteile des Bandes durch Stanzen entfernt und die entstandenen Kanten anschließend poliert.For reasons of strength healds for high performance looms are usually made of tempered steel. These strands are punched out of a steel band. As a bandwidth for the production of such strands for the steel strip worldwide has a width of 5.5 mm to 6 mm as Standard enforced. Because the strands should be as light as possible due to the high weaving speeds, despite the high specific mass of the steel, the largest possible portions of the strip are removed by punching along the strand longitudinal direction and then polished the resulting edges.

Durch das Ausstanzen von Abschnitten des Bandes während des Fertigungsprozesses entstehen große Abfallmengen, die entsorgt werden müssen. Hieraus erwächst das Bestreben den Einsatz von Rohmaterial zur Herstellung von Weblitzen zu senken.Cutting out sections of the strip during the manufacturing process creates large amounts of waste that must be disposed of. This results in a desire to lower the use of raw material for the production of healds.

Die CH 601 532 offenbart Weblitzen aus Draht oder Flachmaterial mit endständig angesetzten Endösen. Diese bestehen beispielsweise aus Kunststoff.The CH 601 532 discloses healds made of wire or flat material with terminally attached end eyelets. These consist for example of plastic.

Obwohl der Einsatz von Rohmaterial hiermit gesenkt werden kann, entsteht doch eine kritische Verbindungsstelle zwischen Weblitze und Endöse, die bei schnell laufenden Webmaschinen problematisch sein kann.Although the use of raw material can be reduced, this creates a critical connection between heald and end eyelet, which can be problematic in high-speed weaving machines.

Gleiches gilt entsprechend für die CH 410 815 , die Weblitzen aus Flachstahl oder Rundstahl mit angesetzten Endösen zeigt.The same applies accordingly for the CH 410 815 , which shows healds made of flat steel or round steel with attached end eyelets.

Aus der Praxis sind darüber hinaus aus Flachstahl ausgebildete Weblitzen mit einer von Endöse zu Endöse durchgehenden geraden Kante und o-förmigen Endösen bekannt. Jedoch leiden auch diese, wie eingangs dargelegt, unter dem hohen Abfallanfall bei der Herstellung.In practice, trained from flat steel healds with a continuous from Endöse to Endöse straight edge and O-shaped end eyelets are known from practice. However, these also suffer, as stated above, from the high waste production.

Davon ausgehend ist es Aufgabe der Erfindung, eine verbesserte Weblitze anzugeben.On this basis, it is an object of the invention to provide an improved heald.

Diese Aufgabe wird mit einer Weblitze gemäß Anspruch 1 gelöst:This object is achieved with a heddle according to claim 1:

Die erfindungsgemäße Weblitze weist einen länglichen einstückig ausgebildeten Litzenkörper auf, in dem ein Fadenauge ausgebildet ist und an dessen Enden Endösen ausgebildet sind. Die Weblitze besteht somit einschließlich Fadenauge und Endösen aus einem einzigen vorzugsweise nahtlosen Teil, das beispielsweise durch Ausstanzen aus einem entsprechenden Stahlband hergestellt werden kann. An einer Seite weist der Litzenkörper eine gerade Kante auf, die sich über seine gesamte Länge von Endöse zu Endöse und über diese hinaus erstreckt. Diese Kante legt eine Litzenlängsrichtung fest. Quer zu dieser lässt sich sowohl die Fadenaugenbreite als auch die Endösenbreite messen. Die Endösenbreite ist dabei höchstens doppelt so groß wie die Fadenaugenbreite. Nachdem die Größe insbesondere die Breite des Fadenauges die schwächste und mechanisch am stärksten beanspruchte Stelle der Weblitze darstellt, kann diese Breite ein Mindestmaß nicht unterschreiten. Soweit es sich bei der Erfindung um eine Weblitze für schnell laufende Webmaschinen handelt, d.h. für Weblitzen, die für hohe Webgeschwindigkeiten geeignet sind, ist die Fadenauggröße nicht größer als 5,5 mm x 1,2 mm (Innenmaß). Entsprechend kann die äußere Breite des Fadenauges ein Mindestmaß nicht unterschreiten. Erfindungsgemäß werden nun die Endösen in ihrer Breite, wie oben angegeben, beschränkt, so dass der Stanzabfall minimiert wird. Dies obwohl auch das Innenmaß der Endösen nicht willkürlich festgelegt werden kann. Vielmehr ist es durch die Litzentragschienenbreite vorgegeben. Der Erfinder hat jedoch erkannt, dass die äußeren Abmessungen der Endösen auf das angegebene Maß reduziert werden können.The heald according to the invention has an elongate, integrally formed strand body in which a thread eye is formed and at the ends of which end loops are formed. The heald, including the thread eye and the end eyelets, thus consists of a single, preferably seamless part, which can be produced, for example, by punching out a corresponding steel strip. On one side, the heddle body has a straight edge which extends over its entire length from end to end eye and beyond. This edge defines a strand longitudinal direction. In addition to this, both the thread eye width and the end loop width can be measured. The Endösenbreite is at most twice as large as the thread eye width. After the size especially the width of the thread eye represents the weakest and mechanically most stressed point of the heald, this width can not be less than a minimum. As far as in the invention is a heald for high-speed looms, ie for heddles that are suitable for high weaving speeds, the Fadenauggröße is not greater than 5.5 mm x 1.2 mm (inside dimension). Accordingly, the outer width of the thread eye can not be less than a minimum. According to the invention, the end eyelets are now limited in their width, as indicated above, so that the punching waste is minimized. This although the inside dimension of the end eyelets can not be arbitrarily set. Rather, it is predetermined by the Litzentragschienenbreite. The inventor has recognized, however, that the outer dimensions of the end loops can be reduced to the specified extent.

Mit den angegebenen Maßnahmen wird nicht nur der Stanzabfall minimiert sondern es wird auch das Litzengewicht herabgesetzt, was weitere Steigerungen der Webgeschwindigkeiten möglich macht.With the specified measures not only the punching waste is minimized but it also reduces the strand weight, which makes further increases in weaving speeds possible.

Weist das Fadenauge mindestens die oben angegebene Innenweite (5,5 mm in Längsrichtung und 1,2 mm in Querrichtung) auf, können automatische Einziehmaschinen zum Kettfadeneinzug verwendet werden.If the thread eye has at least the inside width indicated above (5.5 mm in the longitudinal direction and 1.2 mm in the transverse direction), automatic retraction machines can be used for the warp thread feed.

Es hat sich als zweckmäßig herausgestellt, wenn die Breite der Endöse mindestens das 1,8-fache der Breite der Weblitze im Bereich des Fadenauges beträgt. Auf diese Weise wird eine mehr als ausreichende Endösenstabilität erreicht. Dies insbesondere wenn die Endöse als geschlossener ungefähr rechteckiger Ring ausgebildet ist. Solche Endösen werden auch als o-förmige Endösen bezeichnet. Vorzugsweise weist eine solche Endöse zwei zueinander im Wesentlichen parallele längliche Stege auf, die wiederum vorzugsweise vollkommen gerade ausgebildet sind. Einer dieser Stege grenzt an die gerade Kante (und bildet einen Abschnitt derselben) während der andere Steg an der gegenüber liegenden Litzenseite angeordnet ist. Vorzugsweise ist der an die gerade Kante grenzende Steg breiter als der von der geraden Kante beabstandete Steg. Dies bietet zumindest zwei Vorteile. Zunächst wird auf diese Weise die von der Litzentragschiene in die Weblitze eingeleitete Beschleunigungs- oder Bremskraft oder überhaupt jede von der Litzentragschiene auf die Litze übertragene Kraft zuverlässig und mit geringer Litzenbelastung übertragen. Des Weiteren ergibt sich ein relativ großer Querversatz zwischen einer die Endösen miteinander verbindenden Mittellinie und dem Fadenauge. Dies vergrößert den Abstand der Fadenaugen bei Litzenanordnungen mit doppeltem Fadenaugstand, was häufig erwünscht ist.It has proved to be expedient if the width of the end eyelet is at least 1.8 times the width of the heald in the region of the thread eye. In this way, a more than adequate Endösenstabilität is achieved. This in particular when the end eyelet is formed as a closed approximately rectangular ring. Such end eyelets are also referred to as o-shaped end eyelets. Such an end eye preferably has two mutually substantially parallel elongate webs, which in turn are preferably formed completely straight. One of these webs adjoins (and forms a portion of) the straight edge while the other web is located on the opposite strand side. Preferably, the web adjacent to the straight edge is wider than the web spaced from the straight edge. This offers at least two advantages. First of all, in this way, the acceleration or braking force introduced by the heddle support rail into the heddle or any force transmitted to the strand by the heddle support rail becomes reliable and transferred with low strand load. Furthermore, there is a relatively large transverse offset between a center line connecting the end eyelets and the thread eye. This increases the distance of the thread eyes in strand assemblies with double thread suction, which is often desirable.

Es hat sich dabei als vorteilhaft herausgestellt, wenn der an die gerade Kante grenzende Steg eine Breite aufweist, die wenigstens 1,6 mal so groß ist wie die Breite des anderen Stegs. Hier werden die oben genannten Vorteile in besonderem Maße erreicht.It has proven to be advantageous if the adjacent edge of the straight web has a width which is at least 1.6 times as large as the width of the other web. Here are the above benefits achieved in particular.

Während die an einer Seite der Weblitze liegende Kante auf einer Geraden liegt, ist die gegenüber liegende Kante vorzugsweise in Abschnitte unterteilt, die jeweils für sich genommen gerade sind, wobei sie jedoch auf zueinander parallelen Linien liegen. Damit lässt sich einerseits das Litzengewicht minimieren und andererseits eine stabile zugfeste Litze gestalten.While the edge lying on one side of the heald lies on a straight line, the opposite edge is preferably divided into sections, each being straight on their own, but lying on mutually parallel lines. On the one hand, this allows the strand weight to be minimized and, on the other hand, to design a stable tension-resistant strand.

Vorzugsweise ist zwischen dem Fadenauge und den Endösen an dem Litzenkörper ein Abschnitt vorgesehen, der eine Breite aufweist, die geringer ist als die Breite des Fadenauges. Dadurch kann das Litzengewicht weiter minimiert werden.Preferably, a portion is provided between the thread eye and the end eyelets on the heddle body, which has a width which is smaller than the width of the thread eye. As a result, the strand weight can be further minimized.

Die Breite des Litzenkörpers beträgt an dem Fadenauge vorzugsweise mindestens 2,3 mm und weiter vorzugsweise maximal 2,6 mm. Diese Abmessungen haben sich für die weitaus meisten Fälle, bei denen mit sehr hoher Webgeschwindigkeit gearbeitet werden soll, als zweckmäßig herausgestellt.The width of the heddle body is preferably at least 2.3 mm and more preferably at most 2.6 mm at the thread eye. These dimensions have been found to be useful for the vast majority of cases where very high weaving speed is desired.

Vorzugsweise ist der Litzenkörper an seinem Fadenauge geschränkt. Dies bedeutet, dass ein Teil des Litzenkörpers, der das Fadenauge umgibt, etwas aus der Ebene heraus gedreht ist, die von dem Flachmaterial des übrigen Litzenkörpers festgelegt ist. Diese Maßnahme erleichtert den Kettfadenlauf.Preferably, the heddle body is set against its thread eye. This means that a part of the strand body which surrounds the thread eye is slightly rotated out of the plane defined by the flat material of the other strand body. This measure facilitates the warp thread run.

Der Litzenkörper ist vorzugsweise aus vergütetem Stahl hergestellt. Andere Flachmaterialien können bedarfsweise Anwendung finden. Das Flachmaterial kann mit ein oder mehreren Wellen versehen sein, die benachbarte Litzen auf Abstand halten. Die Wellen bedingen außerdem eine gewisse Federwirkung, die vorteilhaft sein kann.The heddle body is preferably made of tempered steel. Other flat materials may find application as needed. The sheet may be provided with one or more shafts which keep adjacent strands spaced. The waves also require a certain spring action, which can be advantageous.

Es ist möglich, an dem Litzenkörper vorzugsweise in der Nähe der Endösen Transportöffnungen und/oder Separieröffnungen vorzusehen, die ein normales Handling der Weblitzen gestatten.It is possible to provide transport openings and / or separating openings on the heddle body preferably in the vicinity of the end eyelets, which permit normal handling of the healds.

Diese sind einstückiger Bestandteil des Litzenkörpers 4, d.h. aus dem gleichen Material wie dieser ausgebildet und schließen nahtlos an ihn an. Der Litzenkörper 4 ist beispielsweise einschließlich seiner Endösen 5, 6 durch Ausstanzen aus einem flachen Stahlblechstreifen hergestellt.The heddle 1 has a long narrow strip-shaped heddle body 4, at the ends of which end loops 5, 6 are formed. These are an integral part of the heddle body 4, i. made of the same material as this and seamlessly connect to it. The heddle body 4 is made, for example, including its end loops 5, 6 by punching from a flat sheet steel strip.

Der Litzenkörper 4 weist in einem zwischen den Endösen 5, 6 gelegenen Bereich ein Fadenauge 7 auf, das durch eine vorzugsweise längliche Öffnung 8 gebildet wird. Die Öffnungslängsrichtung 9 ist vorzugsweise in Weblitzenlängsrichtung, d.h. etwa parallel zu der Symmetrielinie 3 orientiert. Der Litzenkörper 4 weist eine sich von der Endöse 5 bis zu der Endöse 6 erstreckende gerade Kante 10 auf. Diese geht an den Endösen 5, 6 jeweils in eine gerundete oder einem Polygonzug folgende Abschlusskante über. Die gerade Kante 10 ist parallel zu der Symmetrielinie 3 orientiert. Die gegenüber liegende Kante 11 ist, wie insbesondere aus Figur 3 ersichtlich ist, zu beiden Seiten des Fadenauges 7 in Abschnitte 12, 13, 14 unterteilt, die jeweils für sich genommen gerade sind und zwischen denen kurze bogenförmige oder auch gerade Übergangsabschnitte vorhanden sind. Die Abschnitte 12, 13, 14 sind parallel zu der Symmetrielinie 3 orientiert. Sie sind jedoch parallel gegeneinander versetzt, wobei die außerhalb der Endöse 5 (sowie 6) liegenden Abschnitte 13, 14 auf der gleichen Seite der Symmetrielinie 3 liegen wie die Kante 10. Mit anderen Worten, die Symmetrielinie 3 verläuft nur an den Endösen 5, 6 durch den Litzenkörper 4 und ansonsten außerhalb desselben. Die Symmetrielinie 3 geht mittig durch Öffnungen 15, 16 in den Endösen 5, 6. Die Öffnungen 15, 16 dienen der Aufnahme der Litzentragschiene. Sie sind vorzugsweise etwa rechteckig ausgebildet. Mit anderen Worten, die Endösen 5, 6 und das Fadenauge 7 sind an dem Litzenkörper 4 in Bezug aufeinander vorzugsweise so angeordnet, dass, wenn zwei gleiche Weblitzen 1, 2 wie in Figur 1 veranschaulicht mit doppeltem Fadenaugstand angeordnet werden, zwischen den Fadenaugen 7, 7' in seitlicher Durchblickrichtung ein Spalt 25 verbleibt. Die seitliche Durchblickrichtung steht senkrecht auf der Zeichenebene und somit senkrecht auf den Flachseiten der Weblitzen.The heald body 4 has in a located between the end loops 5, 6 area a thread eye 7, which by a preferably elongated opening 8 is formed. The opening longitudinal direction 9 is preferably oriented in the heddle longitudinal direction, ie approximately parallel to the symmetry line 3. The heddle body 4 has a straight edge 10 extending from the end eyelet 5 to the end eyelet 6. This is at the end loops 5, 6 each in a rounded or a traverse following trailing edge. The straight edge 10 is oriented parallel to the symmetry line 3. The opposite edge 11 is, as can be seen in particular from FIG. 3, divided on both sides of the thread eye 7 into sections 12, 13, 14, which in each case are straight and between which short arcuate or also straight transition sections are present. The sections 12, 13, 14 are oriented parallel to the symmetry line 3. However, they are offset from each other in parallel, wherein the outside of the end eyelet 5 (and 6) lying portions 13, 14 lie on the same side of the line of symmetry 3 as the edge 10. In other words, the line of symmetry 3 extends only at the end eyelets 5, 6th through the heddle body 4 and otherwise outside of it. The symmetry line 3 passes centrally through openings 15, 16 in the end eyelets 5, 6. The openings 15, 16 serve to receive the heddle support rail. They are preferably formed approximately rectangular. In other words, the end loops 5, 6 and the thread eye 7 are preferably arranged on the heddle body 4 with respect to each other such that, when two identical healds 1, 2 are arranged with double thread suction as illustrated in FIG. 1, between the thread eyes 7, 7 'in the lateral direction of view, a gap 25 remains. The lateral direction of view is perpendicular to the plane of the drawing and thus perpendicular to the flat sides of the healds.

Der Litzenkörper 4 besteht, wie insbesondere auch aus Figur 2 ersichtlich ist, aus einem Flachmaterial, wie beispielsweise Stahlblech. Seine in Figur 2 sichtbare Dicke ist wesentlich geringer als die Breite des Litzenkörpers 4 zwischen den Endösen 5, 6. Gemäß Figur 3 ist der Litzenkörper 4 an seinen Endösen quer zu der Kante 10 gemessen am breitesten. Seine Breite A (siehe Figur 3 oben) ist 1,8 mal bis 2 mal so groß wie die in gleicher Richtung zu messende Breite D in dem Bereich des Fadenauges 7, d.h. gemessen innerhalb des Abschnitts 14 der Kante 11 (siehe Figur 3). Noch geringer ist die in gleicher Richtung gemessene Breite C des Litzenkörpers 4 in dem Abschnitt 13.The stranded body 4 consists, as is apparent in particular from Figure 2, of a flat material, such as steel. Its thickness, which is visible in FIG. 2, is substantially smaller than the width of the heddle body 4 between the end loops 5, 6. According to FIG. 3, the heddle body 4 is widest at its end eyes, measured transversely to the edge 10. Its width A (see FIG. 3 above) is 1.8 times to 2 times greater than the width D to be measured in the same direction in the region of the thread eye 7, i. measured within the portion 14 of the edge 11 (see Figure 3). Even smaller is the width C measured in the same direction of the stranded body 4 in the section 13.

Wie insbesondere aus Figur 3 hervorgeht, wird die im Wesentlichen rechteckige Öffnung 15 der Endöse 5 von zwei Stegen 17, 18 begrenzt, die parallel und in Längsrichtung d.h. der Richtung der geraden Kante 10 orientiert sind. Die beiden selbst geraden Stege 17, 18 sind Teil des Litzenkörpers 4, d.h. einstückiger Bestandteil desselben. Sie sind jeweils parallelflankig begrenzt, d.h. sie weisen über ihre ganze, in Richtung der Symmetrieachse 3 zu messenden Länge eine einheitliche Breite auf. Der Steg 17 grenzt an die gerade Kante 10 und definiert einen Abschnitt derselben. Der gegenüber liegende Steg 18 bildet einen Teil des Abschnitts 12 der Kante 11. Die Stege 17, 18 sind an beiden Enden (in den Figuren oben und unten) mit dem übrigen Litzenkörper und somit miteinander verbunden. Der Steg 18 ist schmaler als der Steg 17. Gleiches gilt entsprechend für die Endöse 6. Dadurch verläuft die Symmetrielinie 3 parallel zu der geraden Kante 10. Der Versatz zwischen der geraden Kante 10 und der Symmetrielinie 3 (oder auch einer zu der geraden Kante 10 parallelen, durch das Fadenauge 7 gehenden Linie und der Symmetrielinie 3) ist durch die unterschiedlichen Stegbreiten der Stege 17, 18 größer als es bei gleich breiten Stegen der Fall wäre. Dadurch wird der aus Figur 1 ersichtliche Abstand der Öffnungslängsrichtungen 9, 9' der beiden Fadenaugen 7, 7' der benachbarten Weblitzen 1, 2 größer als es bei symmetrischen Endösen 5, 6 der Fall wäre.As can be seen in particular from FIG. 3, the essentially rectangular opening 15 of the end eye 5 is delimited by two webs 17, 18 which are oriented parallel and in the longitudinal direction, ie, the direction of the straight edge 10. The two straight webs 17, 18 are part of the stranded body 4, ie the same integral part. They are each bounded parallel-sided, ie they have a uniform width over their entire length to be measured in the direction of the symmetry axis 3. The web 17 adjoins the straight edge 10 and defines a portion thereof. The opposite web 18 forms part of the portion 12 of the edge 11. The webs 17, 18 are connected at both ends (in the figures above and below) with the rest of the strand body and thus with each other. The web 18 is narrower than the web 17. The same applies accordingly to the end eyelet 6. As a result, the line of symmetry 3 extends parallel to the straight edge 10. The offset between the straight edge 10 and the symmetry line 3 (or even to the straight edge 10th parallel, passing through the thread eye 7 line and the line of symmetry 3) by the different web widths of the webs 17, 18 is greater than would be the case with equally wide webs. As a result, the apparent from Figure 1 distance of the opening longitudinal directions 9, 9 'of the two thread eyes 7, 7' of the adjacent healds 1, 2 larger than symmetrical end eyelets 5, 6 would be the case.

Im Bereich der Endösen 5, 6 sind Transportöffnungen 19, 20 ausgebildet, die beispielsweise durch kreisrunde Öffnungen gebildet werden. Sie sind vorzugsweise mittig zu der Symmetrielinie 3 angeordnet und dienen dazu, die Weblitzen 1, 2 bündelweise zu transportieren. Die Transportöffnungen 19, 20 der Weblitzen 1, 2 sind somit deckungsgleich.In the region of the end eyelets 5, 6 transport openings 19, 20 are formed, which are formed for example by circular openings. They are preferably arranged centrally to the symmetry line 3 and serve to transport the healds 1, 2 in bundles. The transport openings 19, 20 of the heddles 1, 2 are thus congruent.

Des Weiteren weist die Weblitze 1 vorzugsweise Separieröffnungen 21, 22 auf, mit denen die Litzen in der Position der Weblitzen 1 und die Weblitzen in der Position der Weblitzen 2 jeweils separat aufgenommen werden können.Furthermore, the heald 1 preferably has separating openings 21, 22 with which the strands in the position of the healds 1 and the healds in the position of the healds 2 can each be received separately.

Eine weitere optionale aber zweckmäßige Maßnahme ist die Ausbildung von aus Figur 2 ersichtlichen Wellen 23, 24 an den Endösen 5, 6. Diese sind vorzugsweise bezüglich der Endöse 5, 6 außermittig angeordnet, so dass sie, wie Figur 2 erkennen lässt, benachbarte Weblitzen 1, 2 an unterschiedlichen Stellen gegeneinander abstützen. Außerdem sind sie in ihrem mittleren Bereich um das jeweilige Fadenauge 7 herum geschränkt, d.h. das Flachmaterial ist dort aus seiner sonst eingenommenen Ebene heraus gedreht, um das Fadenauge 7 etwas in Kettfadenrichtung zu drehen.Another optional but expedient measure is the formation of waves 23, 24 visible at FIG. 2 at the end loops 5, 6. These are preferably arranged eccentrically with respect to the end eyelets 5, 6, so that, as FIG. 2 shows, adjacent healds 1 , 2 against each other at different locations. In addition, they are in their central area around the respective thread eye 7 around, i. the flat material is there rotated out of its otherwise occupied plane to turn the thread eye 7 something in the warp direction.

Die erfindungsgemäße Weblitze lässt sich aus Flachmaterial durch Stanzen herstellen. Die erforderliche Breite für das Stahlband entspricht dabei der Breite der Endöse 5 (bzw. 6). Diese setzt sich aus der Breite des Stegs 17, der Breite des Stegs 18 und der erforderlichen Breite der dazwischen liegenden Öffnung 15 zusammen. Durch die unterschiedliche Bemessung der Breiten der Stege 17, 18, insbesondere die Verminderung der Breite des Stegs 18, ergibt sich eine Gesamtbreite A für das Fadenauge 5 (sowie 6), die geringer ist als bei herkömmlichen Weblitzen. Dennoch wird der gewohnte Abstand zwischen der Symmetrielinie 3 und der Öffnung 8 des Fadenauges 7 erreicht. Somit kann mit vermindertem Materialeinsatz eine leichtere und somit schnellere Weblitze geschaffen werden, die in bestehende Webschäfte und Websysteme passt.The heddle according to the invention can be produced from flat material by punching. The required width for the steel strip corresponds to the width of the end eyelet 5 (or 6). This is composed of the width of the web 17, the width of the web 18 and the required width of the intermediate opening 15 together. The different dimensioning of the widths of the webs 17, 18, in particular the reduction of the width of the web 18, results in a total width A for the thread eye 5 (and 6), which is lower than in conventional healds. Nevertheless, the usual distance between the line of symmetry 3 and the opening 8 of the thread eye 7 is achieved. Thus, with a reduced use of materials a lighter and thus faster heald be created, which fits into existing heald frames and weaving systems.

Eine verbesserte Weblitze besteht aus einem Flachmaterial, beispielsweise vergütetem Stahl. Sie weist geschlossene (o-förmige) Endösen 5, 6 auf, die einstückiger Bestandteil des Litzenkörpers 4 sind. Eine sich über die gesamte Länge der Weblitze 1 erstreckende, längs verlaufende Kante 10 ist vollkommen gerade ausgebildet. Die gegenüber liegende Kante 11 besteht hingegen aus gegeneinander versetzten geraden Stücken. Eine Besonderheit der erfindungsgemäßen Weblitze liegt darin, dass die in den Endösen 5, 6 ausgebildeten Öffnungen 15, 16 zur Aufnahme der Litzentragschiene in der Endöse 5, 6 außermittig angeordnet sind. Dadurch weisen die beiden die Öffnung 15, 16 begrenzenden Stege 17, 18 unterschiedliche Breiten auf. Bei vermindertem Materialeinsatz und Gewicht wird eine Weblitze erhalten, die hinsichtlich der Stabilität und der Verwendbarkeit in bestehenden Websystemen herkömmlichen Weblitzen mindestens ebenbürtig ist.An improved heald consists of a flat material, for example tempered steel. It has closed (O-shaped) end loops 5, 6, which are an integral part of the heddle body 4. A along the entire length of the heald 1 extending, longitudinal edge 10 is formed completely straight. The opposite edge 11, however, consists of staggered straight pieces. A special feature of the heddle according to the invention lies in the fact that the openings 15, 16 formed in the end eyes 5, 6 are arranged off-center in the end eye 5, 6 for receiving the heddle support rail. As a result, the two webs 17, 18 delimiting the opening 15, 16 have different widths. With reduced material usage and weight, a heald is obtained that is at least equal to conventional healds in terms of stability and usability in existing weaving systems.
