Description

Die Beschreibung betrifft einen Reißverschluß mit gewebten Tragbändern und darin eingewebten Verschlußgliederreihen aus Kunststoffmonofilament, wobei die Tragbänder aus Kettfäden und nebeneinanderliegenden Doppelschüssen eines kontinuierlichen Grundschußfadens aufgebaut sind, wobei die Verschlußgliederreihen jeder Reißverschlußhälfte aus einer kontinuierlichen, beim Webvorgang erzeugten Schraubenwendel mit als Kunststoffmonofilament-Doppelschuß ausgeführten Verschlußgliedern aus Kuppelköpfen sowie daran anschließenden, in einer Projektion auf die Reißverschlußebene weitgehend übereinanderliegenden Schenkeln bestehen und rückwärtige Verbindungsteile vorgesehen sind, wobei die Doppelschüsse der Grundschußfäden in einer Projektion auf die Reißverschlußebene unter den Verschlußgliedern und ohne Überfassung des Kunststoffmonofilamentes zwischen den Verschlußgliedern angeordnet und einige der Kettfäden der Tragbänder als Bindekettfäden über die Verschlußglieder geführt sind, und wobei die Doppelschüsse zwischen den Verschlußgliedern durch zumindest einen der Bindekettfäden als Grundschußfaden-Abstützschlaufe bis in den Bereich der oberen Schenkel der Verschlußglieder gezogen sind. In dem Teilmerkmal, daß die Doppelschüsse der Grundschußfäden ohne Überfassung des Kunststoffmonofilamentes geführt sind, kommt konkret zum Ausdruck, daß diese Doppelschüsse die rückwärtigen Verbindungsteile nicht überlassen, sondern unterlassen. Solche Reißverschlüsse können bekanntlich mit modernen Nadelwebautomaten bei großer Webgeschwindigkeit erstellt werden, wobei die Nadeln einerseits die Grundschußladen-Doppelschüsse und andererseits die Verschlußglieder als Monofilament-Doppelschüsse eintragen.The description relates to a zipper with woven straps and rows of fastener elements woven into them made of plastic monofilament, the fastener straps being made up of warp threads and adjacent double wefts of a continuous base weft thread, the fastener rows of each half of the fastener consisting of a continuous helix made of plastic monofilament fasteners produced during the weaving process Dome heads and adjoining legs, which are largely superimposed in a projection onto the zipper plane, and rear connecting parts are provided, the double wefts of the base weft threads being arranged in a projection onto the zipper plane under the fastener members and without covering the plastic monofilament between the fastener members and some of the warp threads of the carrier tapes as binding warp threads over the breech eder are guided, and wherein the double wefts between the fastener elements are drawn through at least one of the binding warp threads as a base weft support loop into the region of the upper legs of the fastener elements. The partial feature that the double wefts of the base weft threads are guided without covering the plastic monofilament expresses concretely that these double wefts do not leave the rear connecting parts, but omit them. As is known, such zippers can be produced with modern needle weaving machines at high weaving speeds, the needles entering the basic weft loading double wefts on the one hand and the closure members on the other hand as monofilament double wefts.

Reißverschlüsse des eingangs beschriebenen Aufbaus sind in verschiedenen Ausführungsformen bekannt. Dabei ist es auch bekannt (DE-C-3 347 067), eine zweite Bindekettfadenanordnung mit zumindest einem Bindekettfaden so zuzuführen, daß die Doppelschüsse der Tragbänder zwischen den Verschlußgliedern überfaßt und die Verschlußglieder mit den darum liegenden Doppelschuß unterfaßt sind. Hier unterfassen die Bindekettfäden in jeder Periode zumindest zwei Verschlußglieder, davon eines mit dem darunterliegenden Doppelschuß und eines ohne den darunterliegenden Doppelschuß. Die Biegefestigkeit und die Aufreifelfestigkeit des Verbundes der Verschlußgliederreihen und der Tragbänder an den Enden eines solchen Reißverschlusses im Bereich der Bindekettfäden sind hier verbesserungsfähig.Zippers of the construction described above are known in various embodiments. It is also known (DE-C-3 347 067) to supply a second binding warp thread arrangement with at least one binding warp thread in such a way that the double wefts of the carrier tapes are covered between the fastener elements and the fastener elements with the double weft around them. Here, the binding warp threads underlie at least two fastener links in each period, one with the double weft underneath and one without the double weft underneath. The bending strength and the tearing strength of the composite of the rows of fastener elements and the carrying tapes at the ends of such a zipper in the region of the binding warp threads can be improved here.

Bei Reißverschlüssen des eingangs beschriebenen Aufbaus (DE-C-3 007 276, DE-C-3 022 032) kann im übrigen mit verschiedenen Bindungen und mit unterschiedlichem Rapport in bezug auf die Bindekettfäden gearbeitet werden. Die Anordnung ist stets so getroffen, daß zwei Verschlußglieder in einer Kettfadentasche angeordnet sind. Das hat sich bewährt, jedoch ist auch hier die Biegesteifigkeit in bezug auf die Biegungen in der Reißverschlußebene und aus der Reißverschlußebene heraus verbesserungsfähig. Das gilt auch für die Aufreifelfestigkeit.In the case of zippers of the construction described at the beginning (DE-C-3 007 276, DE-C-3 022 032), it is also possible to work with different bindings and with different repeats in relation to the binding warp threads. The arrangement is always such that two fastener elements are arranged in a warp thread pocket. This has proven itself, but here too the bending stiffness with respect to the bends in the zipper plane and from the zipper plane can be improved. This also applies to the pick resistance.

Der Erfindung liegt das technische Problem zugrunde, bei einem Reißverschluß des eingangs beschriebenen Aufbaus die Biegefestigkeit, aber auch die Aufreifelfestigkeit, zu verbessen. Das gilt nach bevorzugter Ausführungsform der Erfindung fernerhin in bezug auf das sogenannte Ausgleichsverhalten` wenn zwei Hälften eines nicht gekuppelten Reißverschlusses im Zusammenhang mit dem Einnähen um ein geringes Maß im Schieber gegeneinander verzogen werden, um danach die Kupplungsfähigkeit durch Schieberbetätigung sicherzustellen. Insgesamt strebt die Erfindung in bezug auf die Reduzierung der Biegesteifigkeit, die Aufreifelfestigkeit sowie in bezug auf das Ausgleichsverhalten optimierende Verbesserungen an, und zwar ohne Beeinträchtigung der Querzugfestigkeit und der Knickfestigkeit.The invention is based on the technical problem of improving the flexural strength but also the contact strength in the case of a zipper of the construction described at the beginning. According to a preferred embodiment of the invention, this also applies in relation to the so-called compensation behavior if two halves of a non-coupled zipper are warped by a small amount in the slider in connection with the sewing in, in order to then ensure the coupling ability by actuating the slider. Overall, the invention aims for improvements with regard to the reduction of the bending stiffness, the contact resistance as well as improvements with regard to the compensation behavior, without impairing the transverse tensile strength and the buckling strength.

Zur Lösung dieses technischen Problems ist Gegenstand der Erfindung ein Reißverschluß mit gewebten Tragbändern und darin eingewebten Verschlußgliederreihen aus Kunststoffmonofilament, wobei die Tragbänder aus Kettfäden und nebeneinanderliegenden Doppelschüssen eines kontinuierlichen Grundschußfadens aufgebaut sind, wobei die Verschlußgliederreihen jeder Reißverschlußhälfte aus einer kontinuierlichen, beim Webvorgang erzeugten Schraubenwendel mit als Kunststoffmonofilament-Doppelschuß ausgeführten Verschlußgliedern aus Kuppelköpfen sowie daran anschließenden, in einer Projektion auf die Reißverschlußebene weitgehend übereinanderliegenden Schenkeln bestehen und rückwärtige Verbindungsteile vorgesehen sind, wobei die Doppelschüsse der Grundschußfäden in einer Projektion auf die Reißverschlußebene unter den Verschlußgliedern und ohne Überfassung des Kunststoffmonofilamentes zwischen den Verschlußgliedern angeordnet und einige der Kettfäden der Tragbänder als Bindekettfäden über die Verschlußglieder geführt sind, wobei die Doppelschüsse zwischen den Verschlußgliedern durch zumindest einen der Bindekettfäden als Grundschußfaden-Abstützschlaufe bis in den Bereich der oberen Schenkel der Verschlußglieder gezogen sind und wobei die Kombination der folgenden Merkmale eingerichtet ist:

  • a) Eine erste Bindekettfadenanordnung mit mehreren Bindekettfäden ist so geführt, daß diese Bindekettfäden die zwischen den Verschlußgliedern bis in den Bereich der oberen Schenkel der Verschlußglieder gezogenen Doppelschüsse der Tragbänder stets untergreifen sowie zumindest zwei Verschlußglieder überfassen und im Anschluß an die überfaßten Verschlußglieder lediglich ein Verschlußglied unterfassen, und zwar mit dem darunterliegenden Doppelschuß,
  • b) eine zweite Bindekettfadenanordnung mit zumindest einem Bindekettfaden ist so geführt, daß die Doppelschüsse der Tragbänder zwischen den Verschlußgliedern überfaßt und die Verschlußglieder mit dem darunterliegenden Doppelschuß unterfaßt sind,
wobei die Anordnung so getroffen ist, daß die von einem Bindekettfaden der ersten Bindekettfadenanordnung zusammen mit dem darunterliegenden Doppelschuß unterfaßten Verschlußglieder auch von einem Bindekettfaden der zweiten Bindekettfadenanordnung unterfaßt sind.To solve this technical problem, the subject of the invention is a zip fastener with woven carrier tapes and rows of fastener links woven from plastic monofilament, the fastener tapes being constructed from warp threads and adjacent double wefts of a continuous base weft thread, the fastener rows of each half of the zip fastener consisting of a continuous helix produced during the weaving process Plastic monofilament double weft fastener members made of dome heads and adjoining legs, which are largely superimposed in a projection onto the zipper plane and rear connecting parts are provided, the double wefts of the base weft threads being arranged in a projection onto the zipper plane under the fastener members and without covering the plastic monofilament between the fastener members and some of the warp threads on the fastener tapes are guided as binding warp threads over the fastener links, the double wefts between the fastener links being drawn through at least one of the binding warp threads as a base weft thread support loop into the region of the upper legs of the fastener links and the combination of the following features being established:
  • a) A first binding warp thread arrangement with a plurality of binding warp threads is guided so that these binding warp threads always engage under the double wefts of the carrier tapes drawn between the fastener elements up to the area of the upper limbs of the fastener elements and include at least two fastener elements and only one fastener element after the fastener elements covered , with the double shot underneath,
  • b) a second binding warp thread arrangement with at least one binding warp thread is guided in such a way that the double wefts of the carrier tapes are covered between the fastener elements and the fastener elements with the double weft underneath,
the arrangement being such that the fastener members enclosed by a binding warp thread of the first binding warp thread arrangement together with the double weft underneath are also covered by a binding warp thread of the second binding warp thread arrangement.

Die Erfindung beruht auf der Erkenntnis, daß es für die Lösung der Aufgabe wesentlich ist, daß bei dem Reißverschluß des eingangs beschriebenen Aufbaus mit als Kunststoffmonofilament-Doppelschüssen ausgeführten Verschlußgliedern gleichzeitig die Merkmale a) und b) verwirklicht sind. Die Kombination insgesamt führt dazu, daß die einzelnen Verschlußglieder, d.h. die entsprechenden Monofilament-Doppelschüsse, in einer Bindekettfadentasche angeordnet sind. Faßt man den Verbund der Verschlußgliederreihen bildlich als eine Kette auf (man spricht in diesem Sinne auch von der Reißverschlußkette), so wird erfindungsgemäß die Anzahl der Kettenglieder gegenüber den bekannten Ausführungsformen mit zwei Verschlußgliedern in einer Bindekettfadentasche gleichsam verdoppelt. Dadurch wird die Biegesteifigkeit reduziert. Überraschenderweise werden die Querzugfestigkeit und die Knickfestigkeit nicht beeinträchtigt.The invention is based on the knowledge that it is essential for the solution of the problem that the features a) and b) are simultaneously realized in the zipper of the structure described at the beginning with closure members designed as plastic monofilament double wefts. The combination as a whole leads to the individual closure members, i.e. the corresponding monofilament double wefts are arranged in a binding warp thread pocket. If the connection of the rows of fastener links is figuratively regarded as a chain (one also speaks of the zip fastener chain in this sense), then according to the invention the number of chain links is quasi doubled compared to the known embodiments with two fastener links in a binding warp thread pocket. This reduces the bending stiffness. Surprisingly, the transverse tensile strength and the buckling strength are not impaired.

Bei einem Reißverschluß, der zwar gewebte Tragbänder und eingewebte Verschlußgliederreihen aus Kunststoffmonofilament aufweist, jedoch im übrigen von anderer Art ist, ist es bekannt (DE 28 55 370 C2), Bindekettfäden ähnlich wie vorstehend angegeben zu führen, jedoch ohne daß die Bindekettfäden der ersten Bindekettfädenanordnung im Anschluß an die überfaßten Verschlußglieder ein Verschlußglied mit dem darunterliegenden Doppelschuß der Grundschußfäden unterfassen. Von anderer Art ist dieser bekannte Reißverschluß, weil die Verschlußgliederreihen nicht als Kunststoffmonofilament-Doppelschüsse ausgeführt und als solche bei einem Webvorgang mit einer oder mit zwei besonderen Schußeintragungsnadeln erzeugt sind. Die Verschlußgliederreihen sind vielmehr mit Hilfe einer im Webautomaten angeordneten, textiltechnisch fremden Maschine, nämlich mit Hilfe einer Wickelmaschine mit Wickeldorn, schraubenwendelförmig geformt und bei der Fachbildung als Windung einer Schraubenwendel lediglich eingewebt. Das ist aufwendig. Die bei diesen Reißverschlüssen bekannte Art der Einbindung der Verschlußgliederreihen trägt zur Erhöhung der Biegefestigkeit nicht bei, die vielmehr durch einen Füllfaden bestimmt ist, und verbessert auch nicht die Aufreifelfestigkeit. Die Doppelschüsse der Grundschußfäden, die die rückwärtigen Verbindungsteile überfassen, kommen mit den Flanken des Reißverschlußschiebers in Kontakt und verschleißen vorzeitig.In the case of a zipper, which although it has woven straps and woven rows of fastener elements made of plastic monofilament, is otherwise of a different type, it is known (DE 28 55 370 C2) to guide binding warp threads similar to the one indicated above, but without the binding warp threads of the first binding warp thread arrangement following the covered closure members, a closure member with the Underneath the double weft of the base weft threads. This known zipper is of a different kind because the rows of fastener members are not designed as plastic monofilament double wefts and as such are produced during a weaving process with one or two special weft insertion needles. Rather, the rows of fastener elements are helically shaped with the help of a textile-technical machine arranged in the weaving machine, namely with the aid of a winding machine with a winding mandrel, and are only woven into the shed as a turn of a helical coil. It is expensive. The known way of integrating the rows of fastener elements in these zippers does not contribute to increasing the flexural strength, which is rather determined by a filler thread, and also does not improve the pick-up strength. The double wefts of the base weft threads, which cover the rear connecting parts, come into contact with the flanks of the zipper slide and wear prematurely.

Es versteht sich, daß die Bindung entsprechend einzurichten ist, und zwar in bezug auf die Struktur im einzelnen, aber auch in bezug auf die Spannung der Bindekettfäden. Das äußert sich im fertigen Reißverschluß unter anderem durch das Bindekettfaden-Einlaufverhältnis. Unter Bindekettfaden-Einlaufverhältnis versteht man das Verhältnis der Länge eines nicht eingebundenen Bindekettfadens zur Länge der sogenannten Reißverschlußkette, aus der der erfindungsgemäße Reißverschluß hergestellt ist. Eine bevorzugte Ausführungsform der Erfindung ist in diesem Zusammenhang dadurch gekennzeichnet, daß die Bindekettfäden der ersten Bindekettfadenanordnung mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 1,25 : 1 bis 1,35 : 1 angeordnet sind. Bewährt hat sich eine Ausführungsform, bei der die Bindekettfaden der ersten Bindekettfadenanordnung mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 1,28 : 1 bis 1,32 : 1 angeordnet sind. Entsprechend lehrt die Erfindung, daß der zumindest eine Bindekettfaden der zweiten Bindekettfadenanordnung mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 2,50 bis 3,50 angeordnet ist. Hier hat sich eine Ausführungsform bewährt, bei der zumindest der eine Bindekettfaden der zweiten Bindekettfadenanordnung mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 2,80 bis 3,20 angeordnet ist. Die Einlaufverhältnisse gelten für Reißverschlüsse mit Kuppelgliederreihen aus Monofilament von 0,48 bis 0,50 mm Dicke und zugehöriger Kuppelgliederreihen-Dicke von 1,1 bis 1,4 mm. Werden höhere Monofil-Dicken eingesetzt, so vergrößern sich die absoluten Einlaufwerte.It goes without saying that the binding must be set up accordingly, specifically with regard to the structure, but also with regard to the tension of the binding warp threads. This manifests itself in the finished zipper, among other things, by the binding warp thread running-in ratio. The binding warp thread running-in ratio is understood to mean the ratio of the length of a binding warp thread that has not been bound to the length of the so-called zipper chain from which the zipper according to the invention is produced. In this context, a preferred embodiment of the invention is characterized in that the binding warp threads of the first binding warp thread arrangement are arranged with a binding warp thread running-in ratio in the range from 1.25: 1 to 1.35: 1. An embodiment has proven itself in which the binding warp threads of the first binding warp thread arrangement are arranged with a binding warp thread running-in ratio in the range from 1.28: 1 to 1.32: 1. Accordingly, the invention teaches that at least a binding warp thread of the second binding warp thread arrangement is arranged with a binding warp thread running-in ratio in the range from 2.50 to 3.50. Here, an embodiment has proven itself in which at least one binding warp thread of the second binding warp thread arrangement is arranged with a binding warp thread running-in ratio in the range from 2.80 to 3.20. The running-in conditions apply to zippers with rows of fastener elements made of monofilament with a thickness of 0.48 to 0.50 mm and associated fastener rows with a thickness of 1.1 to 1.4 mm. If higher monofilament thicknesses are used, the absolute shrinkage values increase.

Um bei einem erfindungsgemäßen Reißverschluß auch das eingangs beschriebene Ausgleichsverhältnis zu verbessern, ist Gegenstand der Erfindung eine weitere Kombination mit den vorstehend beschriebenen Kombinationsmerkmalen, nämlich

  • c) eine dritte Bindekettfadenanordnung mit zumindest einem Bindekettfaden ist so geführt, daß die Doppelschüsse der Tragbänder zwischen den Verschlußgliedern, die als Grundschußfaden-Abstützschlaufe hochgezogen sind, unterfaßt, die Verschlußglieder aber überfaßt sind,
wobei die erste und die zweite Bindekettfadenanordnung nahe den rückwärtigen Verbindungsteilen, die dritte Bindekettfadenanordnung nahe den Kuppelköpfen angeordnet ist. In diesem Zusammenhang empfiehlt es sich, die Anordnung so zu treffen, daß der zumindest eine Bindekettfaden der dritten Bindekettfadenanordnung mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 1,10 bis 1,20 angeordnet ist. Bewährt hat sich hier ein Bindekettfaden-Einlaufverhältnis von 1,14 bis 1,18.In order to improve the compensation ratio described at the outset in a zipper according to the invention, the subject of the invention is a further combination with the combination features described above, namely
  • c) a third binding warp thread arrangement with at least one binding warp thread is guided in such a way that the double wefts of the carrying tapes between the fastener elements, which are pulled up as a base weft thread support loop, are underpinned, but the fastener elements are covered,
wherein the first and the second binding warp thread arrangement are arranged near the rear connecting parts, the third binding warp thread arrangement is arranged near the coupling heads. In this context, it is advisable to arrange such that the at least one binding warp thread of the third binding warp thread arrangement is arranged with a binding warp thread running-in ratio in the range from 1.10 to 1.20. A binding warp thread running-in ratio of 1.14 to 1.18 has proven itself here.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. So weist nach bevorzugter Ausführungsform der Erfindung die erste Bindekettfadenanordnung drei Bindekettfäden auf, die jeweils um zwei Schußeintragungen gegeneinander versetzt sind. So weist nach einer anderen bevorzugten Ausführungsform der Erfindung die erste Bindekettfadenanordnung vier Bindekettfäden auf, die jeweils um zwei Schußeintragungen gegeneinander versetzt sind. Die erste Bindekettfadenanordnung ist zweckmäßigerweise im Rapport hoch/tief/hoch/tief/tief/tief oder im Rapport hoch/tief/hoch/tief/tief/tief/hoch/tief so geführt, daß zwei oder drei Verschlußglieder überfaßt sind. Die zweite Bindekettfadenanordnung ist zweckmäßigerweise im Rapport tief/hoch geführt, die dritte im Rapport hoch/tief. Im Rahmen der Erfindung liegt es, die Bindekettfäden der ersten und/oder zweiten und/oder dritten Bindekettfadenanordnung auf den Schenkeln der Verschlußglieder mehrfach nebeneinander anzuordnen. Im Rahmen der Erfindung liegt es, zwischen den Verschlußgliedern und den darunter angeordneten Doppelschüssen der Grundschußfäden zumindest einen weiteren als Stehfaden ausgeführten Bindekettfaden anzuordnen.There are several options for further training and design within the scope of the invention. Thus, according to a preferred embodiment of the invention, the first binding warp thread arrangement has three binding warp threads, each offset from one another by two weft entries. According to another preferred embodiment of the invention, the first binding warp thread arrangement has four binding warp threads, each of which is offset from one another by two weft entries. The first binding warp thread arrangement is expediently guided in the repeat high / deep / high / deep / deep / deep or in the repeat high / deep / high / deep / deep / deep / high / deep such that two or three fastener elements are covered. The second binding warp thread arrangement is expediently guided low / high in the repeat, the third in the repeat high / low. It is within the scope of the invention to arrange the binding warp threads of the first and / or second and / or third binding warp thread arrangement several times next to one another on the legs of the fastener elements. It is within the scope of the invention to arrange at least one further binding warp thread designed as a standing thread between the closure members and the double wefts of the base weft threads arranged underneath.

Besonders bewährt hat sich eine Ausführungsform eines erfindungsgemäßen Reißverschlusses, bei dem die Tragbänder aus Polyesterfäden und die Monofilamente der Verschlußglieder aus einem Werktoff der Gruppe Polyamid, vorzugsweise PA 6.6, oder aus Polyester-Butylenterephthalat bestehen.An embodiment of a zipper according to the invention has proven particularly useful, in which the carrier tapes consist of polyester threads and the monofilaments of the fastener elements consist of a polyamide material, preferably PA 6.6, or of polyester-butylene terephthalate.

Der in den Figuren dargestellte Reißverschluß ist ein Reißverschluß mit gewebten Tragbändern 1 und mit darin eingewebten Verschlußgliederreihen 2 aus Kunststoffmonofilament. Die Tragbänder 1 bestehen aus Kettfäden 3 und nebeneinanderliegenden Doppelschüssen 4 eines kontinuierlichen Grundschußfadens. Die Verschlußgliederreihen 2 jeder Reißverschlußhälfte bestehen aus einer kontinuierlichen, beim Webvorgang erzeugten Schraubenwendel mit Verschlußgliedern 5 aus Kuppelköpfen 6 und daran anschließenden, in einer Projektion auf die Reißverschlußebene weitgehend übereinanderliegenden Schenkeln 7. Außerdem sind rückwärtige Verbindungsteile 8 vorgesehen.The zipper shown in the figures is a zipper with woven carrying straps 1 and with rows of fastener elements 2 made of plastic monofilament woven into it. The carrier tapes 1 consist of warp threads 3 and adjacent double wefts 4 of a continuous base weft thread. The rows of fastener elements 2 of each half of the zip fastener consist of a continuous helix, produced during the weaving process, with fastener elements 5 made of coupling heads 6 and adjoining legs 7, which are largely superimposed in a projection onto the zip fastener plane. In addition, rear connecting parts 8 are provided.

Die Anordnung ist so getroffen, daß die Doppelschüsse 4 in einer Projektion auf die Reißverschlußebene unter den Verschlußgliedern 5 und zwischen den Verschlußgliedern 5 angeordnet und einige der Kettfäden 3 der Tragbänder als Bindekettfäden über die Verschlußglieder 5 geführt sind. Die Doppelschüsse 4 zwischen den Verschlußgliedern 5 sind durch zumindest einen der Kettfaden 3 als Grundschußfaden-Abstützschlaufe bis in den Bereich der oberen Schenkel 7 der Verschlußglieder 5 gezogen.The arrangement is such that the double wefts 4 are arranged in a projection onto the zipper plane below the fastener elements 5 and between the fastener elements 5 and some of the warp threads 3 of the carrier tapes are guided over the fastener elements 5 as binding warp threads. The double wefts 4 between the closure members 5 are pulled through at least one of the warp threads 3 as a base weft support loop into the region of the upper legs 7 of the closure members 5.

Aus einer vergleichenden Betrachtung der Fig. 1 und 3 bzw. 1 und 4 entnimmt man, daß eine erste Bindekettfadenanordnung mit mehreren Bindekettfäden 31, 32, 33 bzw. 31, 32, 33, 34 so geführt ist, daß diese Bindekettfäden die Doppelschüsse 4 der Tragbänder 1 stets untergreifen sowie zumindest zwei Verschlußglieder 5 überfassen und im Anschluß daran ein Verschlußglied 5 mit dem darunterliegenden Doppelschuß 4 unterfassen. Außerdem ist eine zweite Bindekettfadenanordnung mit zumindest einem Bindekettfaden 35 so geführt, daß die Doppelschüsse 4 der Tragbänder 1 zwischen den Verschlußgliedern 5 überfaßt und die Verschlußglieder 5 mit dem darunterliegenden Doppelschuß 4 unterfaßt sind. Die Anordnung ist insgesamt so getroffen, daß die von einem Bindekettfaden 31, 32, 33 bzw. 31, 32, 33, 34 der ersten Bindekettfadenanordnung zusammen mit dem darunterliegenden Doppelschuß 4 unterfaßten Verschlußglieder 5 auch von dem zunächst einem Bindekettfaden 35 der zweiten Bindekettfadenanordnung unterfaßt sind.1 and 3 or 1 and 4, it can be seen that a first binding warp thread arrangement with a plurality of binding warp threads 31, 32, 33 or 31, 32, 33, 34 is guided such that these binding warp threads are the double wefts 4 of the Always grasp under the carrying straps 1 and cover at least two closure members 5 and then enclose a closure member 5 with the double weft 4 underneath. In addition, a second binding warp thread arrangement with at least one binding warp thread 35 is guided such that the double shots 4 of the carrier tapes 1 between the shutter members 5 and the shutter members 5 with the double shot 4 underneath are covered. The overall arrangement is such that the fastener elements 5, which are covered by a binding warp thread 31, 32, 33 or 31, 32, 33, 34 of the first binding warp thread arrangement together with the double weft 4 underneath, are also covered by the binding warp thread 35 of the second binding warp thread arrangement .

Von besonderer Bedeutung ist im Rahmen der Erfindung das Bindekettfaden-Einlaufverhältnis. Dieses ist definiert als das Verhältnis der Länge eines nicht eingebundenen Bindekettfadens 3 zur Länge der sogenannten Reißverschlußkette, aus der der erfindungsgemäße Reißverschluß hergestellt ist und die aus den Tragbändern 1 und den Verschlußgliederreihen 2 besteht. Das Bindekettfaden-Einlaufverhältnis ist in den Figuren ausreichend erkennbar, und zwar in bezug auf die Bindekettfäden 31, 32, 33 bzw. 31, 32, 33, 34 der ersten Bindekettfadenanordnung im Bereich von 1,25 : 1 bis 1,35 : 1. Der zumindest eine Bindekettfaden 35 der zweiten Bindekettfadenanordnung ist demgegenüber mit einem Bindekettfaden-Einlaufverhältnis im Bereich von 2,50 bis 3,50 angeordnet.The binding warp thread running-in ratio is of particular importance in the context of the invention. This is defined as the ratio of the length of a non-bound binding warp thread 3 to the length of the so-called zipper chain, from which the zipper according to the invention is made and which consists of the carrier tapes 1 and the rows of fastener links 2. The binding warp thread running-in ratio is sufficiently recognizable in the figures, specifically in relation to the binding warp threads 31, 32, 33 and 31, 32, 33, 34 of the first binding warp thread arrangement in the range from 1.25: 1 to 1.35: 1. In contrast, the at least one binding warp thread 35 of the second binding warp thread arrangement is arranged with a binding warp thread running-in ratio in the range from 2.50 to 3.50.

Die Ausführungsbeispiele betreffen diejenige Ausführungsform, bei der auch das eingangs erläuterte Ausgleichsverhalten optimiert ist. Man erkennt eine dritte Bindekettfadenanordnung mit zumindest einem Bindekettfaden 36, die so geführt ist, daß die Doppelschüsse 4 der Tragbänder 1 zwischen den Verschlußgliedern 5, die als Grundschußfaden-Abstützschlaufe hochgezogen sind, unterfaßt, die Verschlußglieder 5 aber überfaßt sind. Im übrigen ist die Anordnung so getroffen, daß die erste und die zweite Bindekettfadenanordnung mit den Bindekettfäden 31 bis 35 nahe den rückwärtigen Verbindungsteilen 8, die dritte Bindekettfadenanordnung mit dem zumindest einen Bindekettfaden 36 nahe den Kuppelköpfen 6 angeordnet ist. Hier liegt das Bindekettfaden-Einlaufverhältnis im Bereich von 1,10 bis 1,20.The exemplary embodiments relate to the embodiment in which the compensation behavior explained at the outset is also optimized. One recognizes a third binding warp thread arrangement with at least one binding warp thread 36, which is guided in such a way that the double wefts 4 of the carrier tapes 1 between the fastener elements 5, which are pulled up as a base weft support loop, underpins the Closure members 5 but are covered. Otherwise, the arrangement is such that the first and the second binding warp thread arrangement with the binding warp threads 31 to 35 near the rear connecting parts 8, the third binding warp thread arrangement with the at least one binding warp thread 36 are arranged near the coupling heads 6. Here the binding warp thread running-in ratio is in the range from 1.10 to 1.20.

Im Ausführungsbeispiel nach der Fig. 4 besitzt die erste Bindekettfadenanordnung drei Bindekettfäden 31, 32, 33, die jeweils über zwei Schußeintragungen gegeneinander versetzt sind. In einem weiteren Ausführungsbeispiel erkennt man in der Fig. 3, daß die erste Bindekettfadenanordnung vier Bindekettfäden 31, 32, 33, 34 aufweist, die jeweils um zwei Schußeintragungen gegeneinander versetzt sind. Für die erste Bindekettfadenanordnung gilt der Rapport des Patentanspruches 11, den man in den Fig. 3 bzw. 4 unschwer nachvollzieht. Für die zweite Bindekettfadenanordnung gilt der Rapport tief/hoch im Ausführungsbeispiel nach den Fig. 1, 2 und 3. Ein anderes Ausführungsbeispiel der zweiten Bindekettfadenanordnung (35) zeigt die Fig. 4. Hier sind 2 Bindekettfäden (35) um zwei Schußeintragungen gegeneinander versetzt und im Rapport hoch/hoch/tief/hoch geführt, für die dritte Bindekettfadenanordnung gilt der Rapport hoch/tief. Insoweit ist auch der Rapport hoch/hoch/tief/hoch möglich. - Im Rahmen der Erfindung liegt es, die Bindekettfäden 31 bis 36 der ersten und/oder zweiten und/oder dritten Bindekettfadenanordnung auf den Schenkeln 7 der Verschlußglieder 5 mehrfach nebeneinander anzuordnen.In the exemplary embodiment according to FIG. 4, the first binding warp thread arrangement has three binding warp threads 31, 32, 33 which are each offset from one another by two weft entries. In a further embodiment, it can be seen in FIG. 3 that the first binding warp thread arrangement has four binding warp threads 31, 32, 33, 34, which are each offset by two weft entries. For the first binding warp thread arrangement, the repeat of claim 11 applies, which is easily understood in FIGS. 3 and 4. For the second binding warp thread arrangement, the repeat low / high applies in the exemplary embodiment according to FIGS. 1, 2 and 3. Another exemplary embodiment of the second binding warp thread arrangement (35) is shown in FIG. 4. Here, two binding warp threads (35) are offset by two weft entries and in the repeat high / high / low / high, the repeat high / low applies to the third binding warp thread arrangement. In this respect, the repeat high / high / low / high is also possible. It is within the scope of the invention to arrange the binding warp threads 31 to 36 of the first and / or second and / or third binding warp thread arrangement on the legs 7 of the fastener elements 5 several times next to one another.

In den Fig. 3, 5 und 6 erkennt man, daß zusätzlich als Stehfäden 37 geführte Bindekettfäden, die zwischen den Verschlußgliedern 5 und den Doppelschüssen 4 laufen, angeordnet sind.
