Definitions

• the invention relates to a device for carrying out continuous wiring and fixing of continuous wires.
• such devices are used by machines allowing the production of carpet threads.
• This second wire is brought through the barrel of the corresponding pin to a wiring head arranged in the extension of the latter.
• the machine comprises a central frame supporting a plurality of identical working positions each comprising: a double twist or wiring spindle supporting a winding of wire, intended to be twisted or wired with a second wire; wire calling means making it possible to cancel the tension which results from the twisting or wiring operation; wire heating means followed by a cooling zone; means for winding the treated yarn; -
• the heating means are constituted by a rectilinear oven arranged vertically or substantially vertically; the wire goes back and forth inside the oven where the end of the latter is introduced for its lower part, while a call and return system for said wire is provided in the upper part; - Means are provided to maintain the wire under a minimum tension during the cooling phase and to deliver it by means of winding.
• the oven must be brought to a relatively high temperature of the order of 210 ° C. and must have large dimensions.
• the length or height of the oven can reach 4.50 meters.
• Such means can be constituted by a relaxation mat arranged horizontally below the oven. This mat can be either individual for each working position, or common to all positions and then extends over the entire length of the loom.
• the problem which the invention proposes to solve is to omit the oven, thus making it possible to overcome dimensional characteristics, while having the objective of less heating the wire so as to have at least the cool, which also reduces the power of the installation.
• a device for wiring and / or double-twisting the wire of the type of those comprising, in a known manner: has been designed and developed.
• the heating means are constituted by at least one cylindrical cup associated with a return guide to allow the hauling of the wire, said cup being brought to a determined temperature and positively driven in rotation .
• the cooling zone comprises at least one cylindrical bucket-return guide assembly ensuring the hauling of the wire, said assembly being located between the heating bucket and the winding means.
• Another problem which the invention proposes to solve is to improve the efficiency of the heating means according to the invention.
• the device comprises, between the call means and the heating cup, a means of application on the wire, of a heat transfer fluid.
