Description

       

   <EMI ID=1.1> 

  
on connaît des cordelières de, tirage sans fin. Ces cordelières sont souvent tressées de telle manière que les floches entourent une âme réalisée en corde ou analogue.

  
Les cordelières en service connues ont cependant l'inconvénient que les couches de tresses glissent légèrement, de telle sorte que l'on n'est pas sûr de pouvoir effectuer une manoeuvre de jalousie ou analogues exempte de perturbation. Cet inconvénient se présente surtout lorsque les cordelières sont placées sur une roue d'entraînement et tirées dans deux directions.

  
Pour y porter remède, il est proposé,conformément à l'invention, de pourvoir une cordelière formée de manière connue d'une âme entourée d'une ou plusieurs tresses d'une ou aussi de plusieurs coutures piquées. Grâce

  
à ces coutures piquées on arrive à ce que la tresse extérieure'est'réunie si fermement aux fils intérieurs de l'âme qu'un glissement de la tresse sur les fils soit exclu. Grâce à de telles coutures piquées la cordelière est tellement parfaite que l'on peut obtenir une manoeuvre régulière des jalousies et analogues,

  
Il suffit qu'on entoure éventuellement la cordelière par une seule couture piquée; on peut. cependant aussi disposer deux coutures piquées de préférence se plaçant sous un angle de 900 ou encore même une pluralité de coutures,

  
On peut pourvoir finalement dans de telles cor-

fils terminaux centraux et appliquer alors sur. ceux-ci la ou les coutures piquées.

  
Dans le dessin deux exemples de réalisation con. formes à l'invention sont représentés . schématiquement en coupe au travers de la cordelière à échelle fortement agrandie.

delière. Cette âme est entourée de fils tressés 2, qui sont disposés autour de l'âme de manière habituelle par une machine à tresser.

  
 <EMI ID=5.1> 

  
au travers de cette cordelière, par exemple, une couture piquée perpendiculaire 3, qui est représentée en Fig.1 par une ligne double en traits interrompus. Grâce à cette ' couture piquée, on réalise une liaison entre les fils tressés extérieurs et les fils intérieurs de l'âme. Comme il est indiqué en Fig.1, on peut aussi encore appli-

che de tresses, qui est 'indiquée par les fils tressés 5 et 6, Ces fils tressés sont munis de fils terminaux centraux 7, qui se placent parallèlement à l'âme 1. Sur cette première couche de tresses peut être disposée une seconde couche, qui est indiquée par les fils tressés 8 et 9.

  
Ces derniers fils englobent aussi.par au-dessus et par en-dessous des.fils terminaux centraux supplémentaires 10.

  
Dans cette forme de réalisation est prévue aussi une couture piquée 3, qui traverse l'âme et les fils ter-

  
 <EMI ID=8.1> 

  
est indiquée par des lignes d.oubles décalées. Bien entendu, dans cette forme de réalisation une. seconde., couture piquée pourrait être aussi placée perpendiculairement à la première. 

  
Ces cordelières tressées sans fin avec les coutures piquées conviennent très bien pour permettre une traction sur les deux cotés, sans qu'il ne soit à craindre que les couches de tresses glissent sur l'âme. 

  
 <EMI ID=9.1> 

  
pour jalousies, caractérisée en ce que la cordelière constituée de fils d'âme (1) entourés d'une ou plusieurs couches de tresses est pourvue d'une ou plusieurs coutures piquées (3, 4).



   <EMI ID = 1.1>

  
we know cords of endless pulling. These cords are often braided in such a way that the floches surround a core made of cord or the like.

  
However, the cords in use known in service have the drawback that the layers of braids slip slightly, so that it is not certain that a jealousy or similar maneuver can be carried out without disturbance. This disadvantage arises especially when the cords are placed on a drive wheel and pulled in two directions.

  
To remedy this, it is proposed, in accordance with the invention, to provide a cord formed in a known manner with a core surrounded by one or more braids of one or also more stitched seams. Grace

  
at these stitched seams it is possible that the outer braid is united so firmly to the inner threads of the core that slipping of the braid on the threads is excluded. Thanks to such stitched seams the cord is so perfect that one can obtain a regular operation of the blinds and the like,

  
It suffices if the cord is possibly surrounded by a single stitched seam; we can. however also have two stitched seams preferably placed at an angle of 900 or even a plurality of seams,

  
One can finally provide in such cor-

  
 <EMI ID = 2.1>

  
central terminal wires and then apply on. these or the stitched seams.

  
In the drawing two examples of embodiment con. forms of the invention are shown. schematically in section through the cord on a greatly enlarged scale.

deliere. This core is surrounded by braided threads 2, which are arranged around the core in the usual way by a braiding machine.

  
 <EMI ID = 5.1>

  
Through this cord, for example, a perpendicular stitched seam 3, which is represented in Fig.1 by a double line in dotted lines. Thanks to this stitched seam, a connection is made between the outer braided threads and the inner threads of the core. As shown in Fig. 1, one can also still apply

ple, is placed perpendicular to the stitched seam 3.

  
Fig &#65533;. 2 shows an embodiment, in which - <EMI ID = 7.1>

  
che of braids, which is' indicated by the braided son 5 and 6, These braided son are provided with central terminal son 7, which are placed parallel to the core 1. On this first layer of braids can be arranged a second layer, which is indicated by the braided threads 8 and 9.

  
These latter threads also encompass from above and below additional central terminal threads 10.

  
In this embodiment, a stitched seam 3 is also provided, which passes through the core and the end threads.

  
 <EMI ID = 8.1>

  
is indicated by staggered double lines. Of course, in this embodiment a. second., stitched seams could also be placed perpendicular to the first.

  
These endless braided cords with stitched seams are very suitable for allowing traction on both sides, without having to worry about the layers of braid slipping over the core.

  
 <EMI ID = 9.1>

  
for blinds, characterized in that the cord consisting of core threads (1) surrounded by one or more layers of braids is provided with one or more stitched seams (3, 4).
