Abstract
Description
L'invention est relative à un procédé et à un dispositif pour rendre un câble solidaire d'une enveloppe coulée autour de lui et à ltobiet ainsi réalisé. The invention relates to a method and a device for making a cable integral with an envelope cast around it and to the ltobiet thus produced.
Il existe de nombreux cas où on a besoin de lier rigidement un câble et une enveloppe coulée autour de lui. Mais ces dispositifs sont en général limités à des attaches en bout de câble où il est facile de séparer les brins du toron de façon à permettre une bombe pénétration de la matière coulée entre ceux-ci et à obtenir ainsi un bon accrochage. Il est beaucoup plus difficile d'obtenir un bon accrochage entre un câble et uie résine coulée lorsque cet accrochage doit se faire dans la partie courante d'un câble et lorsque la matiére coulée ne peut être métallique et doit être de la résine synthétique par exemple.De plus, si on prend un câble multi torons, lors du sunnoulage de l'enveloppe des fuites se produisent aux plans de joint de l'outillage, dans les interstices entre les torons. Si on prend un câble monotoron, il n'y a pas de faites, mais après le sunnoulage, en tirant sur le câble, il pourra glisser dans l'enveloppe, ceci étant facilité si on chauffe le câble. There are many cases where there is a need to rigidly tie a cable and a casing cast around it. However, these devices are generally limited to attachments at the end of the cable where it is easy to separate the strands of the strand so as to allow a bomb penetration of the material poured between them and thus to obtain good attachment. It is much more difficult to obtain a good attachment between a cable and a cast resin when this attachment must be done in the current part of a cable and when the material being cast cannot be metallic and must be synthetic resin for example. .Moreover, if a multi-strand cable is taken, during the sunnoulage of the envelope, leaks occur at the joint surfaces of the tool, in the interstices between the strands. If you take a monotoron cable, there are no steps, but after sunnoulage, by pulling on the cable, it can slide in the envelope, this is facilitated if you heat the cable.
L'invention a pour but de remedier à cet inconvénient. A cet effet, selon l'invention, le procédé pour rendre un câble monotoron rigidement solidaire d'une enveloppe est caractérisé en ce que l'on serre, à l'aide de pinces, le câble en deux endroits, distants d'environ six fois le diamètre du câble, en ce que l'on fait tourier les pinces l'une par rapport à l'autre d'une quantité suffisante pour détorolmer la portion de câble située entre elles, puis en ce qu'on exerce une force axiale pour rapprocher les pinces afin de faire ressortir les brins du câble détoroimé lesdits brins s'écartent les uns par rapport aux autres et ménagent un vide dans l'axe du câble, appelé ci-après "bulle", enfin en ce qu'on coule l'enveloppe autour d'une portion du câble libérée des pinces contenant au moins une "bulle" ainsi réalisée. The invention aims to remedy this drawback. To this end, according to the invention, the method for making a single-strand cable rigidly integral with an envelope is characterized in that the cable is clamped, using pliers, in two places, about six apart times the diameter of the cable, in that the clamps are rotated relative to each other by an amount sufficient to detorolate the portion of cable located between them, then in that an axial force is exerted to bring the clamps together in order to bring out the strands of the detoroimed cable, said strands deviate from each other and create a vacuum in the axis of the cable, hereinafter called "bubble", finally in that it flows the envelope around a portion of the cable released from the clamps containing at least one "bubble" thus produced.
Selon l'invention le dispositif comprenant une portion de câble dans laquelle on a exécuté au moins une "bulle" selon le procédé de la
Revendication I et une enveloppe coulée autour de cette portion de câble, de sorte que celle-ci ne puisse pas se désolidariser de l'enveloppe par traction, par rotation, ou par rotation et traction combinées.According to the invention the device comprising a portion of cable in which at least one "bubble" has been executed according to the method of
Claim I and an envelope cast around this portion of cable, so that the latter cannot be detached from the envelope by traction, by rotation, or by combined rotation and traction.
Le dessin ci-joint pennettra d'expliciter cette invention
Sur le câble monotoron (1) on a réalisé selon le procédé décrit cidessus, une bulle (2) constituée des brins du même câble enserrant un vide (4). Lors de la coulée de l'enveloppe (3) avec du zamack ou de la résine synthétique, le produit de coulée va pouvoir s'insérer entre les brins au niveau de la bulle et ainsi remplir le vide (4) et réaliser un accrochage correct.The attached drawing will explain this invention.
On the single-strand cable (1), a bubble (2) consisting of the strands of the same cable enclosing a vacuum (4) was produced according to the method described above. When casting the envelope (3) with zamack or synthetic resin, the casting product will be able to be inserted between the strands at the level of the bubble and thus fill the void (4) and achieve correct attachment .
En tirant sur le câble il ne sera possible qu'éventuellement en détordre une partie, mais il ne sera pas possible de désolidariser le câble de son enveloppe au niveau de la bulle. By pulling on the cable, it will only be possible to untwist part of it, but it will not be possible to separate the cable from its envelope at the bubble.
