Description

Weblitze vorzugsweise zum Verarbeiten von bandförmigem Material und Verfahren zum Herstellen derselben.Heald, preferably for processing strip material and method of making same.

Gegenstand der vorliegenden Erfindung ist eine Weblitze vorzugsweise zum Verarbeiten von bandförmigem Material und ein Verfahren zum Herstellen derselben.The subject of the present invention is a heddle preferably for processing strip material and a method for producing the same.

Weblitzen und ihre Herstellverfahren sind bekannt. Traditionell werden vor allem Fäden und Drähte verwoben. Vor allem in jüngerer Zeit werden auch Bänder mit Weblitzen verwoben. So befasst sich die EP 1 795 636 B1 mit einer Weblitze für bandförmige Kettfäden. Die dort gezeigte Weblitze ist vor allem für die Herstellung technischer Gewebe optimiert, wie sie beispielsweise zur Herstellung von Faserverbundmaterialien Verwendung finden.Healds and their manufacturing methods are known. Traditionally, especially threads and wires are interwoven. Especially in recent times, bands are woven with healds. So that's what the EP 1 795 636 B1 with a heddle for tape-shaped warp threads. The heald shown there is optimized especially for the production of technical fabric, as used for example for the production of fiber composite materials.

Die EP 1 795 636 B1 zeigt eine Litze, die im Wesentlichen aus zwei Bändern besteht, die parallel und in einem Abstand zueinander angeordnet sind.The EP 1 795 636 B1 shows a strand consisting essentially of two bands, which are arranged parallel and at a distance from each other.

In dem Zwischenraum zwischen den Bändern befinden sich Abstandshalter und zwei stangenartige Bauelemente, die das Fadenauge bilden. Die Abstandshalter, nicht aber die stangenartigen Bauelemente, die das Fadenauge bilden, verfügen zum Teil über Befestigungselemente, die jeweils in eine Ausnehmung in einem der Bänder greifen. An den beiden Enden der Bänder befinden sich Endösen, so dass die in der EP 1 795 636 B1 gezeigte Weblitze vier Endösen aufweist. Die vorgenannte Druckschrift macht keine detaillierten Angaben zur Herstellung der gezeigten Weblitzen.In the space between the bands are spacers and two rod-like components that form the thread eye. The spacers, but not the rod-like components that form the thread eye, have some of fasteners that each engage in a recess in one of the bands. At the two ends of the bands are end loops, so that in the EP 1 795 636 B1 shown heddle has four end eyelets. The aforementioned document makes no detailed information for the preparation of the healds shown.

Die in der EP 1 795 636 B1 gezeigte Weblitze ist vor allem für die Herstellung technischer Gewebe optimiert, wie sie beispielsweise zur Herstellung von Faserverbundmaterialien Verwendung finden. Bei der Verarbeitung teurer Materialien wie von CFK-Fäden spielt der Preis der verwendeten Litzen eine eher untergeordnete Rolle.The in the EP 1 795 636 B1 heald shown is optimized especially for the production of technical fabric, as used for example for the production of fiber composite materials use. When processing expensive materials such as CFRP threads, the price of the strands used plays a rather minor role.

Weitere Anwendungen für Litzen zum Verarbeiten von Bändern könnten sich jedoch vor allem in Bereichen der Technik ergeben, die unter größerem Preisdruck stehen als die Hersteller von Faserverbundbauteilen. Ein solcher Bereich ist die Herstellung von Verpackungsmitteln aus bandartigen Kunststoffmateriallen, aus denen Gewebe gebildet werden. Zur Herstellung solcher Verpackungsmaterialien - wie Säcken -werden vor allem Rundwebmaschinen eingesetzt.However, other applications for strands for processing tapes could result, above all, in areas of technology which are under greater price pressure than the manufacturers of fiber composite components. One such area is the production of packaging means from tape-like plastic materials from which fabrics are formed. For the production of such packaging materials - such as sacks - above all circular looms are used.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Weblitze vorzuschlagen, die sich günstig herstellen lässt und die mit einer geringen Breite ausgestattet ist, um in anspruchsvollen Einbaulagen -wie beim Rundweben - zum Einsatz zu kommen.The present invention is therefore based on the object to propose a heald, which can be produced inexpensively and which is equipped with a small width to come in demanding installation positions - as in Rundweben - used.

Zur Lösung der vorgenannten Aufgabe geht die vorliegende Erfindung von einer Weblitze gemäß der vorgenannten Druckschrift EP 1 795 636 B1 aus und löst die Aufgabe mit den Merkmalen des Anspruchs 1. Ein bevorzugtes Herstellverfahren für eine solche Weblitze wird durch den Anspruch 14 vorgeschlagen.To achieve the above object, the present invention is a heald according to the aforementioned document EP 1 795 636 B1 and solves the problem with the features of claim 1. A preferred manufacturing method for such a heddle is proposed by the claim 14.

Zu den weiteren Vorteilen der in Anspruch 1 vorgeschlagenen Litze gehört, dass sie auch bei einer geringen Materialstärke des Bandmaterials eine große Festigkeit aufweist, was die Herstellkosten herabsetzt. Auch die Verbindungspunkte lassen sich in den Abschnitten, in denen die beiden Bänder vorzugsweise mit ihren Flachseiten aneinander anliegen, kostengünstig herstellen. Stoffschlüssige Verbindungsverfahren wie kleben, schweißen oder löten sind hier vorteilhaft einsetzbar. Auch andere Verfahren, die beispielsweise einen Formschluss herbeiführen, wie nieten oder klammern bieten hier Vorteile. Denkbar sind z.B. auch Verbindungspunkte, an denen sich die Bänder gegenseitig durchdringen oder überkreuzen und verrasten. Die konkrete Form der Verbindungspunkte ist in keinem der genannten Verbindungsverfahren auf bestimmte Formen, wie z.B. eine runde Form eingeschränkt, sondern kann jede beliebige, an die Erfordernisse angepasste Form annehmen. Überraschenderweise hat es sich als vorteilhaft erwiesen, wenn die Abstände zwischen den Verbindungspunkten, die dem Fadenauge oberhalb und unterhalb desselben am nächsten sind, und dem Fadenauge selber, gering sind. Durch eine zunehmende Nähe lässt sich unter anderem die Stabilität der Litze steigern. So sind Abstände, die auf der jeweiligen Seite des Fadenauges geringer sind als die Hälfte, ein Drittel, ein Viertel, ein Sechstel, ein Achtel oder gar ein Zehntel des Abstandes zwischen Fadenauge und Endöse vorteilhaft. Ein Abstand von Fadenauge zur Endöse, der zumindest das 1,5-fache des Abstandes des Fadenauges zum Verbindungspunkt beträgt, ist vorteilhaft.Among the other advantages of the proposed in claim 1 strand is that it has a high strength, even with a low material thickness of the strip material, which reduces the manufacturing cost. Also, the connection points can be produced inexpensively in the sections in which the two bands preferably abut each other with their flat sides. Cohesive bonding methods such as bonding, welding or soldering can be used advantageously here. Other methods, for example, bring about a form fit, such as riveting or stapling offer advantages here. Also conceivable, for example, connection points at which the bands penetrate each other or intersect and lock. The concrete form of the connection points is not limited to any of the mentioned connection methods to certain shapes, such as a round shape, but can take any form adapted to the requirements. Surprisingly, it has proved to be advantageous if the distances between the connection points, which are closest to the thread eye above and below it, and the thread eye itself, are low. By increasing proximity can be, inter alia, the stability of Increase strands. Thus, distances which are less than half, one-third, one-fourth, one-sixth, one-eighth or even one-tenth of the distance between thread eye and end eyelet are advantageous on the respective side of the thread eye. A distance from the thread eye to the end eyelet, which is at least 1.5 times the distance of the thread eye to the connection point, is advantageous.

In diesem Zusammenhang ergeben sich auch Vorteile, da die beiden Bänder, die in dem Bereich, in dem das Fadenauge in die Litze eingebracht ist, voneinander beabstandet sind, in der Regel eine Kraft (Normalkraft zur Ebene, die von der Litzenlängsrichtung und der Breitenrichtung der beiden Bänder aufgespannt wird) ausüben, die der Beabstandung der Bänder entgegenwirkt und mit der sich das Fadenauge bzw. das zumindest eine Bauelement, das das Fadenauge begrenzt, zwischen den beiden Bändern festklemmen lässt. Diese Klemmkraft wird umso größer, je näher die beiden dem Fadenauge nächsten Verbindungspunkte zusammenliegen. Für die Schonung des Kettmaterials ist es allerdings vorteilhaft, wenn der Abstand des Fadenauges zum nächsten Verbindungspunkt größer ist als die Breite des Fadenauges. Insbesondere werden dadurch die seitlich an der Litze vorbeigleitenden Nachbarkettbänder geschont.In this connection, there are also advantages in that the two bands which are spaced apart from each other in the region where the thread eye is inserted into the strand usually have a force (normal force to the plane extending from the strand longitudinal direction and the width direction of the strand) two bands is clamped) exercise, which counteracts the spacing of the bands and with which the thread eye or the at least one component that limits the thread eye, can be clamped between the two bands. This clamping force is greater, the closer the two closest to the thread eye connection points. For the protection of the warp material, however, it is advantageous if the distance of the thread eye to the next connection point is greater than the width of the thread eye. In particular, this protects the side adjacent to the strand passing neighboring arches.

Zusätzlich oder alternativ kann eine solche Normalkraft erzeugt werden, indem sich zumindest eines der Bänder (oder beide Bänder) in seiner Einbaulage in einem angespannten Zustand befindet. Dies ist zum Beispiel dann der Fall, wenn das betreffende Band in dem Bereich zwischen den beiden Verbindungspunkten, die dem Fadenauge am nächsten sind, voll ausgelenkt oder gar gelängt wird. Dann kommt unter anderem das Hooksche Gesetz zum Tragen.Additionally or alternatively, such a normal force can be generated by at least one of the bands (or both bands) being in a stressed state in its installed position. This is the case, for example, when the band in question is fully deflected or even elongated in the area between the two connection points which are closest to the thread eye. Then, among other things, the Hooke's law comes into play.

Das zumindest eine Bauelement greift mit einem Befestigungselement in zumindest eines der Bänder ein. Oft wird ein solches Bauelement jeweils zumindest mit einem Befestigungselement in jedes der beiden Bänder eingreifen. In einer vorteilhaften Weiterbildung verfügt zumindest ein Bauelement über Befestigungselemente, die in die beiden Bänder eingreifen. Ein solches Bauelement kann auch über mehr als ein Befestigungselement verfügen, die in ein Band eingreifen. Der Eingriff eines Befestigungselements in ein Band kann dergestalt ausgeführt sein, dass im Band eine Ausnehmung vorhanden ist, die das Band ganz durchbricht. Die Ausnehmung kann auch das Band nur teilweise durchbrechen oder auch derart ausgeführt sein, dass "Ausnehmungen" im Band durch einwärtsragende Materialverformungen hergestellt sind, z.B. auch ohne dass Bandmaterial weggenommen wird. Auf diese oder eine andere Weise (hier zum Beispiel durch Stanzen) können auch Befestigungselemente an dem Band oder beiden Bändern hergestellt werden, die in zumindest ein Bauelement eingreifen.The at least one component engages with a fastening element in at least one of the bands. Often, such a component will engage at least with a fastener in each of the two bands. In an advantageous development, at least one component has fastening elements which engage in the two bands. Such a device may also have more than one fastener which engage in a band. The engagement of a fastener in a band can be designed such that in the band a recess is present that completely breaks the band. The recess may also break the tape only partially or be designed so that "recesses" are made in the band by inwardly projecting material deformations, for example, without tape material is taken away. In this or another way (here, for example, by punching) and fasteners on the band or two bands can be made, which engage in at least one component.

Das Bauelement ist vorzugsweise aus einem Keramikwerkstoff hergestellt, kann aber auch z.B. als Sinter-, MIM- oder Spritzgussteil hergestellt sein.The device is preferably made of a ceramic material, but may also be e.g. be made as a sintered, MIM or injection molded part.

Es ist von Vorteil, wenn ein Befestigungselement über eine Kontaktfläche zu zumindest einem der beiden Bänder verfügt, die als Anschlag dient und daher die Relativbewegung - hier die Annäherung - von Band und Befestigungselement am Anschlagpunkt stoppt.It is advantageous if a fastening element has a contact surface to at least one of the two bands, which serves as a stop and therefore stops the relative movement - here the approach - of tape and fastener at the anchor point.

Bei mehreren Befestigungselementen kann die Kontaktfläche zwischen den Befestigungselementen liegen. Dann kann es vorteilhaft sein, zwischen den Flächen der Befestigungselemente und der Kontaktfläche jeweils einen Freischnitt vorzusehen, um eine möglichst präzise Ausführung der Flächen gewährleisten zu können.For multiple fasteners, the contact surface between the fasteners may be. Then it may be advantageous to provide a free cut between the surfaces of the fastening elements and the contact surface in order to ensure the most accurate possible execution of the surfaces can.

Es ist auch möglich, dass mehrere Kontaktflächen vorliegen, insbesondere auch dann, wenn mehrere Befestigungselemente vorgesehen sind, die z.B. über die Freischnitte hinweg miteinander verbunden sein können.It is also possible that there are a plurality of contact surfaces, in particular even if a plurality of fastening elements are provided, which are e.g. can be connected to each other across the free cuts.

Es können Anstiegsflächen vorliegen, die dazu dienen können, dass die das Fadenauge bildenden Bauelemente durch die Normalkraft der Bänder richtig zu den Bändern positioniert werden und bleiben. Dazu weisen die Anstiegsflächen einen vom rechten Winkel abweichenden Winkel zu der Kontaktfläche auf. Dieser Winkel kann stumpf oder auch spitz ausgeführt sein. Die Kontaktfläche kann auch nur annähernd eben ausgeführt sein oder zumindest einen von 90° abweichenden Winkel zur Mittenlinie des Bauelements aufweisen. Die formmäßige Ausgestaltung der Kontaktfläche kann an die Biegelinie des Bandes angepasst sein, an das sie anstößt. Eine formmäßige Angleichung an die Biegung der Bänder kann für alle Flächenbereiche der Stirnfläche vorteilhaft sein.There may be riser surfaces which may serve to properly position and retain the thread eye forming members by the normal force of the bands. For this purpose, the rising surfaces have a different angle from the right angle to the contact surface. This angle can be made dull or pointed. The contact surface can also be made only approximately flat or at least have an angle deviating from 90 ° to the center line of the device. The shape of the contact surface may be adapted to the bending line of the band to which it abuts. A formal adaptation to the bending of the bands may be advantageous for all surface areas of the end face.

Es hat sich als vorteilhaft erwiesen, das Fadenauge aus zumindest zwei Bauelementen, die das Fadenauge begrenzen, zusammenzusetzen. Oft werden die Bauelemente die Form eines Steges haben. Die Verrundung zumindest der Teile der Bauelemente, die in Kontakt mit den Fäden oder bandartigem Kettmaterial kommen, ist vorteilhaft.It has proved to be advantageous to put the thread eye of at least two components that limit the thread eye. Often, the components will have the shape of a bridge. The rounding of at least the parts of the components which come into contact with the threads or band-like warp material is advantageous.

Aus den verschiedensten Gründen hat es sich als vorteilhaft erwiesen, wenn der Bereich der Endöse frei von Verbindungspunkten bleibt. Auf diese Weise können die in der Regel flexiblen Bänder besser eingehängt werden. Es ist auch vorteilhaft, wenn nur ein Litzenband in zumindest einem Bereich der Endöse - bevorzugt in beiden Endösenbereichen - vorhanden ist. Falls zwei Bänder in zumindest einem Endösenbereich vorhanden sind, ist es möglich, die Endösen der beiden Bänder unterschiedlich zu gestalten. So können sie beispielsweise deckungsgleich geformt und spiegelbildlich oder um 180° um die Bandlängsachse gedreht zueinander ausgerichtet sein. Auch unterschiedliche Formen der Endösen der beiden Bänder bieten sich an.For a variety of reasons, it has proven to be advantageous if the region of the end eyelet remains free of connection points. In this way, the usually flexible tapes can be hung better. It is also advantageous if only one stranded strip is present in at least one region of the end eyelet, preferably in both end eyelet regions. If there are two bands in at least one end loop area, it is possible to make the end loops of the two bands different. Thus, for example, they can be congruently shaped and mirror-inverted or rotated by 180 ° about the tape longitudinal axis to each other. Also, different forms of the end eyelets of the two bands lend themselves to.

Zur Herstellung der in dieser Druckschrift beschriebenen Weblitzen sind die folgenden Verfahrensmerkmale vorteilhaft:

  • Zusammenbringen zweier Bänder entlang ihrer Flachseiten unter Bildung von zumindest zwei Verbindungspunkten, die die Bänder zumindest in Abschnitten ihrer Fläche (Länge in Litzenerstreckungsrichtung) zusammenfügen,
  • Bildung eines Abstandes zwischen den beiden Bändern in dem Teilbereich ihrer Erstreckung in Litzenlängsrichtung, der sich zwischen den zumindest zwei Verbindungspunkten befindet,
  • Einbringen von zumindest einem Bauelement, das ein Fadenauge begrenzt, in den beabstandeten Bereich.
For the production of the healds described in this document, the following process features are advantageous:
  • Bringing together two bands along their flat sides to form at least two connection points which join the bands at least in sections of their surface (length in the direction of strand extension),
  • Forming a distance between the two bands in the portion of their extension in the longitudinal direction of the strand, which is located between the at least two connection points,
  • Introducing at least one component which delimits a thread eye into the spaced area.

Es ist normalerweise vorteilhaft, Einkerbungen und Ausnehmungen in die Bänder einzubringen, bevor diese zusammengebracht und/oder verbunden werden. Insbesondere falls die Bänder deckungsgleich gestaltet sind und/oder falls sie Ausnehmungen an denselben Stellen enthalten, können diese jedoch auch vorgenommen werden, wenn die Bänder bereits zusammengebracht oder sogar bereits verbunden sind. Insbesondere das "Durchstanzen" von Ausnehmungen bietet sich in diesem Fall an. Ggf. erscheint sogar ein Durchstanzen von mehr als zwei Bändern sinnvoll.It is usually beneficial to insert indentations and recesses in the bands before they are brought together and / or joined. In particular, if the bands are designed congruent and / or if they contain recesses in the same places, but these can also be made if the bands already brought together or even already connected. In particular, the "punching through" of recesses is appropriate in this case. Possibly. even a punching through of more than two bands makes sense.

Ein Beabstanden der beiden Bänder in einem Teilbereich ihrer Erstreckung in Litzenlängsrichtung zwischen den zumindest zwei Verbindungspunkten kann nach dem Zusammenbringen und sogar nach dem Bilden der Verbindungspunkte - beispielsweise durch Punktschweißen - erfolgen. Zu diesem Zweck kann ein Keil in den Teilabschnitt der beiden Bänder, die beabstandet werden sollen, eingefahren werden. Es ist in diesem Zusammenhang vorteilhaft, wenn die beiden Bänder in dem betreffenden Teilbereich nicht spielfrei aufeinander liegen. Ein Spalt zwischen den beiden Bändern kann gewährleistet werden, indem ein entnehmbarer Abstandshalter vor dem Zusammenbringen der beiden Bänder in den beabstandeten Bereich eingebracht wird. Der Abstandshalter kann entfernbar sein, er kann jedoch auch als ein permanenter Bestandteil der Litze in dem beabstandeten Bereich verbleiben. Er kann in diesem Fall als ein Bauelement, das das Fadenauge begrenzt, fungieren.A spacing of the two bands in a partial region of their extension in the longitudinal direction of the strand between the at least two connection points can take place after the contacting and even after the formation of the connection points-for example by spot welding. For this purpose, a wedge in the portion of the two bands that are to be spaced, retracted. It is advantageous in this context if the two bands do not rest on each other in the relevant subarea. A gap between the two bands can be ensured by inserting a removable spacer into the spaced area prior to contacting the two bands. The spacer may be removable, but it may also remain as a permanent part of the strand in the spaced area. In this case, it may function as a structural member that limits the thread eye.

Als Abstandshalter können jedoch auch Prägungen eines oder beider Bänder fungieren, wenn die Prägung gegenüber der restlichen Bandoberfläche erhaben und dem anderen Band zugewandt ist. In den genannten Fällen kann das Beabstandungswerkzeug - wie erwähnt in der Regel ein Keil - in den Spalt einfahren und ihn weiter aufweiten.As spacers, however, embossing of one or both bands may also function if the embossment is raised relative to the rest of the band surface and faces the other band. In the cases mentioned, the spacer tool - as mentioned usually a wedge - retract into the gap and further widen it.

Es ist jedoch auch denkbar, den Durchmesser des "Spaltes" so auszulegen, dass es keiner weiteren Beabstandung durch den Keil mehr bedarf. In diesem Fall bestimmt der Abstandshalter also den späteren Abstand der beiden Bänder im Bereich des Fadenauges. Dieser Abstand wird nach dieser Lesart der obigen "Verfahrensmerkmale" also beim Zusammenbringen und nicht danach gebildet, so dass die Verfahrensmerkmale für das letztgenannte Ausführungsbeispiel nicht notwendigerweise aufeinander abfolgen wie Verfahrensschritte. Bringt man allerdings zuerst die beiden Bänder zusammen, um sie anschließend mit einem Beabstandungswerkzeug wieder (ggf. weiter) zu beabstanden (siehe oben, erstgenannte Ausführungsform des Herstellverfahrens), so folgen die obigen Verfahrensmerkmale wie Verfahrensschritte aufeinander ab.However, it is also conceivable to design the diameter of the "gap" so that it requires no further spacing by the wedge. In this case, the spacer thus determines the later distance of the two bands in the region of the thread eye. This distance is formed according to this reading of the above "method features" so when bringing together and not thereafter, so that the process characteristics for the latter embodiment do not necessarily follow each other as process steps. However, if you first bring the two bands together in order to then again with a spacing tool (possibly further) to space (see above, the first-mentioned embodiment of Manufacturing method), then follow the above process characteristics as process steps from each other.

In beiden Fällen ergibt sich ein beabstandeter Bereich (die beiden Bänder sind hier voneinander beabstandet), in den das Fadenauge in irgendeiner Weise eingebracht wird. Dieser beabstandete Bereich erstreckt sich zwischen den zumindest zwei Verbindungspunkten.In both cases, there is a spaced area (the two bands are spaced apart here) into which the thread eye is introduced in some way. This spaced area extends between the at least two connection points.

Die Figuren 1 und 2 zeigen den beabstandeten Bereich 4 einer Ausführungsform einer erfindungsgemäßen Weblitze 1, die sich aus den beiden Bändern 2 und 3 zusammensetzt. Die beiden Bänder 2, 3 sind in dem vorliegenden Ausführungsbeispiel vor ihrem Zusammenbringen mit Prägepunkten 5 versehen worden, die bei der Herstellung der Weblitze 1 als Abstandshalter fungiert haben.The FIGS. 1 and 2 show the spaced portion 4 of an embodiment of a heald according to the invention 1, which is composed of the two bands 2 and 3. The two bands 2, 3 have been provided in the present embodiment, prior to their combination with embossing points 5, which have acted as spacers in the manufacture of the heald 1.

Zwischen den beiden Bändern 2 und 3 sind zwei Bauelemente 6, 7, die das Fadenauge 8 begrenzen, gehalten. Bei dem gezeigten Ausführungsbeispiel verfügen die beiden Bauelemente 6, 7 über Befestigungselemente 9, 10, die in Ausnehmungen 11, 12 in den beiden Bändern 2, 3 eingreifen. In dem gezeigten Ausführungsbeispiel sind die Ausnehmungen 11, 12 Löcher, die durch die Bänder hindurchgehen. Es sind jedoch auch Sacklöcher, die z. B. als Prägungen oder Einkerbungen zustande kommen können, denkbar.Between the two bands 2 and 3 are two components 6, 7, which limit the thread eye 8 held. In the embodiment shown, the two components 6, 7 have fastening elements 9, 10, which engage in recesses 11, 12 in the two bands 2, 3. In the embodiment shown, the recesses 11, 12 are holes that pass through the bands. However, there are blind holes, the z. B. can come about as imprints or indentations, conceivable.

Auch die Figuren 8, 9 sowie 11, 12 und 13 zeigen eine Gesamtansicht oder Elemente der Weblitze 1 nach den Figuren 1 und 2. Anhand der Figuren 8 und 9 wird deutlich, dass die beiden Bänder 2 und 3 durch die beiden Verbindungspunkte 13 und. 14 zusammengehalten werden. Es ist auch denkbar, die beiden Bänder durch drei, vier, fünf oder mehr Verbindungspunkte 13, 14 zusammenzuhalten, oder den Verbindungspunkten eine größere Ausdehnung in der Litzenlängsrichtung I zu geben. Im Bereich der Endösen 15 und 16 befinden sich keine Verbindungspunkte 13, da diese - wie bereits oben erwähnt - vorteilhafterweise in der Nähe des Fadenauges 8 positioniert sind. Aus Figur 8 gehen auch die in der Beschreibung genannten Abstände D, A, und B hervor. D reicht hier von der Mitte des Fadenauges 8 bis zum Ende der Innenkante der Endöse in Litzenlängsrichtung I, mit der die Litze auf der Tragschiene hängt. A reicht von der Mitte des Fadenauges 8 in der Litzenlängsrichtung I bis zum Beginn des Befestigungspunktes 13 auf der dem Fadenauge 8 zugewandten Seite des Befestigungspunktes 13. Figur 8 zeigt auch, dass die Weblitze mit J-förmig ausgeprägten Endösen ausgestattet ist. Es sind in diesem und in allen anderen Ausführungsbeispielen der Erfindung auch C-förmige Endösen an Stelle der J-förmigen Endösen möglich. Die Endösen 17 der beiden Bänder 2 und 3 sind gleich geformt und in einem jeden Endösenbereich 15, 16 gleich ausgerichtet. Die Figur 3 zeigt eine Frontalansicht auf den oberen Endösenbereich 15 der in Figur 8 gezeigten Weblitze 1, bei der nur die in der Ansicht vordere Endöse 17 zu sehen ist. Die Figuren 4 und 5 zeigen einen Endösenbereich 15, bei dem die Endösen 17 gleich geformt sind wie in Figur 3. Allerdings ist die Ausrichtung der Endösen 17 der beiden Bänder 2 und 3 unterschiedlich: Die beiden Endösen 17 sind entlang der Bandlängsachse gegeneinander rotiert.Also the FIGS. 8, 9 and FIGS. 11, 12 and 13 show an overall view or elements of heald 1 according to FIGS FIGS. 1 and 2 , Based on FIGS. 8 and 9 becomes clear that the two bands 2 and 3 through the two connection points 13 and. 14 are held together. It is also conceivable to connect the two bands by three, four, five or more connection points 13, 14, or to give the connection points a greater extension in the strand longitudinal direction I. In the region of the end eyelets 15 and 16 there are no connection points 13, since these - as already mentioned above - are advantageously positioned in the vicinity of the thread eye 8. Out FIG. 8 also the distances D, A, and B mentioned in the description emerge. D reaches here from the middle of the thread eye 8 to the end of the inner edge of the end eye in the longitudinal direction of the strand I, with which the strand hangs on the mounting rail. A extends from the center of the thread eye 8 in the strand longitudinal direction I to the beginning of the attachment point 13 on the thread eye 8 facing side of the attachment point thirteenth FIG. 8 also shows that the heald is equipped with J-shaped end eyelets. It is possible in this and in all other embodiments of the invention, C-shaped end eyelets instead of the J-shaped end eyelets. The end eyelets 17 of the two bands 2 and 3 are the same shape and aligned in each end eyelet region 15, 16 the same. The FIG. 3 shows a frontal view of the upper Endösenbereich 15 of in FIG. 8 shown heald 1, in which only the front end eye 17 can be seen in the view. The FIGS. 4 and 5 show an end eyelet region 15 in which the end eyelets 17 are shaped the same as in FIG FIG. 3 , However, the orientation of the end eyelets 17 of the two bands 2 and 3 is different: The two end eyelets 17 are rotated along the tape longitudinal axis against each other.

Anhand der Figuren 10 bis 12 wird noch einmal die genaue Funktion der Ausnehmungen 11, 12 und der Befestigungselemente 9 und 10 des Ausführungsbeispiels gemäß der Figuren 1 und 2 deutlich. Das in den Figuren 11 und 12 gezeigte Bauelement 7 hat in jeder seiner Stirnseiten 18 zwei Befestigungselemente 9 und 10, die in die Ausnehmungen 11 und 12 der Bänder 2, 3 hineingreifen. Die Befestigungselemente 9 und 10 sind gegenüber der Kontaktfläche 19 erhaben. Die Kontaktfläche begrenzt die Bewegung des Bauelements 7 auf das jeweilige Band 2, 3 zu und fungiert damit als Anschlag. Zwischen der Kontaktfläche 19 und der oberen Anstiegsfläche 21 ergibt sich ein rechter Winkel α. Von der unteren Anstiegsfläche 22 und der Kontaktfläche 19 wird ein (stumpfer) Winkel β aufgespannt, der vom rechten Winkel abweicht. Zwischen den Anstiegsflächen 21 und 22 sind Freischnitte 20 in das Bauteil 7 eingebracht.Based on FIGS. 10 to 12 is again the exact function of the recesses 11, 12 and the fasteners 9 and 10 of the embodiment according to the FIGS. 1 and 2 clear. That in the FIGS. 11 and 12 shown component 7 has in each of its end faces 18, two fastening elements 9 and 10 which reach into the recesses 11 and 12 of the bands 2, 3. The fastening elements 9 and 10 are raised relative to the contact surface 19. The contact surface limits the movement of the component 7 to the respective band 2, 3 and thus acts as a stop. Between the contact surface 19 and the upper riser surface 21, a right angle α. From the lower rising surface 22 and the contact surface 19, a (obtuse) angle β is set, which deviates from the right angle. Between the rising surfaces 21 and 22 free cuts 20 are introduced into the component 7.

Die in den vorgenannten drei Figuren gezeigte Gestaltung der Befestigungselemente ist besonders vorteilhaft. Dabei ist zu beachten, dass die Flächenbereiche der Stirnfläche nicht parallel zur in Figur 12 dargestellten Mittenlinie 27 des Bauelements 7 sind. Der Winkel W1, der zwischen der Stirnfläche des Bestigungselements 9 und der Mittenlinie 27aufgespannt wird, weist die kleinste Abweichung von 90° hin zu kleineren Werten auf. Die Winkel W2 und W3 sind weiter von 90° abweichend, da das Bauelement an die Biegelinie des Bandes angepasst ist. Hierbei wird der Winkel W3 von der Stirnfläche des Befestigungselements 10 und der Mittenlinie 27 aufgespannt. Der Winkel W3 verläuft zwischen der Mittenlinie 27 und der Kontaktfläche 19. In Figur 7 ist der Bereich des Fadenauges 8 einer anderen erfindungsgemäßen Weblitze 1 gezeigt, der verdeutlicht, dass die Ausnehmungen 11, 12 und Befestigungselemente 9, 10 auch in anderer Weise gestaltet sein können. In diesem Ausführungsbeispiel sind die Befestigungselemente 9, 10 durch einen Steg 23 miteinander verbunden. Dementsprechend sind die Ausnehmungen 11, 12 durch eine Nut verbunden.The design of the fastening elements shown in the aforementioned three figures is particularly advantageous. It should be noted that the surface areas of the end face are not parallel to the in FIG. 12 shown center line 27 of the device 7 are. The angle W1 spanned between the end face of the saturation member 9 and the center line 27 has the smallest deviation from 90 ° toward smaller values. The angles W2 and W3 are further deviated from 90 °, since the component is adapted to the bending line of the band. In this case, the angle W3 is spanned by the end face of the fastening element 10 and the center line 27. The angle W3 extends between the center line 27 and the contact surface 19. In FIG. 7 the area of the thread eye 8 of another heald 1 according to the invention is shown, which illustrates that the recesses 11, 12 and fastening elements 9, 10 can also be designed in another way. In this embodiment, the fastening elements 9, 10 are connected by a web 23 with each other. Accordingly, the recesses 11, 12 are connected by a groove.

In Figur 13 ist eine Abwandlung des Bauelements 7 gezeigt. Die in der Figur rechte Kontaktfläche 19 ist hier als im Schnitt (die Zeichnungsebene wird hier von der Litzenlängsrichtung I und der Raumrichtung c der Breite C des Fadenauges 8 aufgespannt) bogenförmige Fläche ohne geraden Bereich ausgeführt.In FIG. 13 a modification of the device 7 is shown. The right in the figure, contact surface 19 is here as in section (the drawing plane is here spanned by the Litzenlängsrichtung I and the spatial direction c of the width C of the thread eye 8) arcuate surface without a straight area running.

Figur 14 zeigt einen Schnitt eines Teilbereichs einer weiteren Ausführungsform der Erfindung, bei der das Befestigungselement 25 Bestandteil des Bandes 3 ist. Das Befestigungslement greift in eine Ausnehmung 26 des Bauelements 7, das ein Fadenauge 8 begrenzt, ein. Es ist bei allen Ausführungsformen der Erfindung von Vorteil, wenn es mehrere solcher Befestigungselemente 25 gibt. Diese können auch von beiden Bändern 2, 3 aus in eines oder mehrere Bauelemente 6, 7 eingreifen.
