Abstract

The process consists in moulding, under pressure, around a textile cord (2), coupling elements (1) such that each one of them has, on the side (1b) opposite the head (1a), parallel to the cord, a groove (6), then in weaving a support strip (3) along the cord, using the cord as an end warp thread and by placing the warp thread (4a) close to the cord in the groove of each coupling element. The warp thread close to the cord which is used is preferably a monofilament made from a thermoplastic material having a diameter greater than the other warp threads. <IMAGE>

Description

La présente invention a pour objet un procédé de fabrication d'une fermeture à glissière comprenant deux moitiés formées chacune d'un ruban-support portant à son bord intérieur une rangée d'éléments d'accouplement obtenus par moulage sous pression,suivant lequel on moule les éléments d'accouplement autour d'un cordonnet textile,puis on tisse,à l'aide d'un métier à tisser des rubans,le long du cordonnet muni d'éléments d'accouplement,un ruban-support destiné à former une moitié de la fermeture,en utilisant le cordonnet comme fil de chaîne placé à l'extrémité de la nappe de fils de chaîne.The present invention relates to a method of manufacturing a zipper comprising two halves each formed by a support tape carrying at its inner edge a row of coupling elements obtained by pressure molding, according to which one molds the coupling elements around a textile cord, then weaving, using a ribbon weaving loom, along the cord provided with coupling elements, a support ribbon intended to form a half of the closure, using the cord as warp thread placed at the end of the warp ply.

Ce procédé permet d'obtenir des fermetures résistantes à éléments d'accouplement de dimensions très réduites.Toutefois, les fermetures obtenues par ce procédé présentent l'inconvénient qui consiste dans la tendance des éléments d'accouplement de tourner autour du cordonnet et d'empêcher ainsi un bon fonctionnement du curseur,donc de la fermeture.This method makes it possible to obtain strong closures with coupling elements of very small dimensions. However, the closings obtained by this method have the drawback which consists in the tendency of the coupling elements to turn around the cord and to prevent thus a good functioning of the cursor, therefore of the closing.

Pour obvier à cet inconvénient,il a été proposé de mouler les éléments d'accouplement autour de deux cordonnets disposés parallèlement.Or,les deux cordonnets étant disposés dans le plan de la fermeture,il est évident que la longueur des éléments d'accouplement moulés autour d'eux est plus grande,ce qui va à l'encontre du but:obtenir des fermetures résistantes à éléments d'accouplement de dimensions minimales.To overcome this drawback, it has been proposed to mold the coupling elements around two cords arranged in parallel. However, the two cords being arranged in the plane of the closure, it is obvious that the length of the molded coupling elements around them is larger, which goes against the goal: to obtain resistant closings with coupling elements of minimum dimensions.

Le but de la présente inevntion est d'obvier aux inconvénients précités.The aim of the present invention is to obviate the aforementioned drawbacks.

A cet effet le procédé selon la présente invention est caractérisé par le fait que l'on moule les éléments d'accouplement de manière que chacun d'eux présente sur le côté opposé à la tête,parallèlement au cordonnet,une rainure et que l'on introduit dans celle-ci,lors du tissage du ruban-support,le fil de chaîne voisin du cordonnet.For this purpose the method according to the present invention is characterized in that the coupling elements are molded so that each of them has on the side opposite the head, parallel to the cord, a groove and that the is introduced into the latter, during the weaving of the support tape, the warp thread adjacent to the cord.

L'invention a également pour objet une fermeture obtenue par ce procédé.The invention also relates to a closure obtained by this process.

Les caractéristiques et les avantages du procédé et de la fermeture selon la présente invention ressortiront plus clairement de la description qui suit et des dessins annexés,donnés à titre d'exemple,dans lesquels:

  • Les Fig. le et 2 montrent,respectivement,une vue en plan et une vue en bout d'une portion d'un cordonnet,munie de deux éléments d'accouplement par le procédé connu.
  • Les Fig. 3 et 4 montrent,respectivement,une vue en plan et une vue en bout d'une portion d'une moitié d'une fermeture obtenue par le procédé connu.
  • La Fig.5 est analogue à la Fig.4 mais avec un élément d'accouplement tourné d'un certain angle sur le cordonnet.
  • Les Fig.6 et 7 montrent,respectivement,une vue en plan et une vue en bout d'une portion d'un cordonnet,munie de deux éléments d'accouplement par le procédé selon la présente invention.
  • Les Fig.8 et 9 montrent,respectivement,une vue en plan et une vue en bout d'une portion d'une moitié d'une fermeture obtenue par le procédé selon la présente invention.
The characteristics and advantages of the method and of the closure according to the present invention will emerge more clearly from the description which follows and from the appended drawings, given by way of example, in which:
  • Figs. le and 2 show, respectively, a plan view and an end view of a portion of a cord, provided with two coupling elements by the known method.
  • Figs. 3 and 4 show, respectively, a plan view and an end view of a portion of one half of a closure obtained by the known method.
  • Fig.5 is similar to Fig.4 but with a coupling element turned at an angle on the cord.
  • Figs. 6 and 7 show, respectively, a plan view and an end view of a portion of a cord, provided with two coupling elements by the method according to the present invention.
  • Figs. 8 and 9 show, respectively, a plan view and an end view of a portion of a half of a closure obtained by the method according to the present invention.

Comme on le voit aux Fig.l à 5,qui se rapportent à la fabrication de fermetures par le procédé connu,les éléments d'accouplement 1 sont moulés d'abord autour d'un cordonnet 2 puis fixés au bord d'un ruban-support 3,lors du tissage de celui-ci,en utilisant le cordonnet 2 comme fil de chalne placé à l'extrémité d'une nappe formée de fils de chaîne 4 entre lesquels on fait passer un fil de trame 5.Aux Fig.3 et 4,on voit que le fil de chaîne 4a,voisin du cordonnet 2,s'ettend le long des éléments d'accouplement l,de sorte que rien ne s'oppose à ce que ces derniers puissent tourner sur le cordonnet 2,comme cela est représenté à la Fig.5.1l est évident que tout élément d'accouplement,qui ne se trouve pas dans le plan du ruban-support 3,constitue un obstacle au bon fonctionnement du curseur,donc de la fermeture.As can be seen in FIGS. 1 to 5, which relate to the manufacture of closures by the known method, the coupling elements 1 are first molded around a cord 2 and then fixed to the edge of a ribbon. support 3, when weaving it, using the cord 2 as a chalne yarn placed at the end of a ply formed of warp threads 4 between which a weft thread 5 is passed. In FIG. 3 and 4, it can be seen that the warp thread 4a, adjacent to the cord 2, extends along the coupling elements l, so that there is nothing to prevent them from turning on the cord 2, as This is shown in Fig. 5.1. It is obvious that any coupling element, which is not in the plane of the support tape 3, constitutes an obstacle to the proper functioning. the cursor, and therefore the closure.

A la Fig.7,qui montre une vue en bout d'une portion d'un cordonnet 2 muni d'éléments d'accouplement 1 par le procédé selon la présente invention,on voit que chacun de ces éléments 1 présente,sur le côté lb opposé à la tête la,une rainure 6.Aux Fig.8 et 9,on voit que,lors du tissage du cordonnet 2 dans le ruban-support 3,1e fil de chaîne 4a,voisin du cordonnet 2,est placé,conformément au procédé selon la présente invention,dans la rainure 6 de chacun des éléments d'accouplement l.Ainsi,le ruban-support 3 est encastré dans chacun des éléments l,de sorte que ceux-ci,du fait de la structure très serrée du ruban,ne peuvent pas tourner sur le cordonnet 2,par rapport au plan du ruban-support 3.In Fig.7, which shows an end view of a portion of a cord 2 provided with coupling elements 1 by the method according to the present invention, it can be seen that each of these elements 1 has, on the side lb opposite the head 1a, a groove 6. In FIGS. 8 and 9, it can be seen that, during the weaving of the cord 2 in the support tape 3.1e warp thread 4a, adjacent to the cord 2, is placed, in accordance to the method according to the present invention, in the groove 6 of each of the coupling elements l. Thus, the support tape 3 is embedded in each of the elements l, so that these, due to the very tight structure of the ribbon, cannot turn on the cord 2, relative to the plane of the support tape 3.

En l'occurrence le fil de chaîne 4a est un monofil en matière thermoplastique ayant un diamètre plus grande que celui des autres fils de chaîne.En effet,il est préférable que le fil de chaîne sur lequel sont ancrés les éléments d'accouplement soit plus robuste et plus rigide.Il est évident que les rainures 6 doivent être compatibles avec le diamètre de ce fil.Ce dernier peut aussi être constitué par un cordonnet textile ou par un cordonnet formé de monofils minces en matière thermoplastique.In this case, the warp thread 4a is a monofilament made of thermoplastic material having a larger diameter than that of the other warp threads. Indeed, it is preferable that the warp thread on which the coupling elements are anchored is more robust and more rigid. It is obvious that the grooves 6 must be compatible with the diameter of this wire. The latter can also be formed by a textile cord or by a cord formed from thin monofilaments made of thermoplastic material.
