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.
• 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 for keeping the wire under a minimum tension during the cooling phase and for delivering 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 produce a thread tinted in the mass and fixed to the continuous.
• 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 device comprises means capable of subjecting the wire to the action of at least one dye.
• FIG. 1 is a schematic view showing the principle of the device according to the invention for carrying out the wiring and the continuous fixing of wire and its coloring;
• FIG. 2 is a perspective view of an advantageous embodiment of the heating and cooling means;
• FIG. 3 is, on a larger scale, a cross-sectional view taken along line 3-3 of Figure 2.
• the device comprises, in a known manner, a double twist or wiring spindle (1) making it possible to carry out either a twisting or a direct wiring operation.
• the spindle driven by an individual motor or by any known and appropriate means, receives a coil (2) of a first wire to be treated (3) called “pot wire”.
• the spindle (1) has a hollow barrel for supplying a second wire (4) called “creel wire” coming from a coil (5).
• the creel wire (4) is brought through the hollow barrel of the spindle to be joined to the pot wire (3) at a wiring head (6).
• the wiring head (6) is of any known and suitable type. At its output, the wires (3) and (4) are assembled by the conventional direct wiring method. Note that the wiring head (6) can be combined with a call means making it possible to cancel the tension resulting from wiring or twisting.
• the means of appeal may essentially consist of an assembly of the capstan and press cylinder type. The association with a grooved cylinder, allows to obtain a hauling of the cabled wire. This results in a very high precision in the speed of call of the wires as well as a cancellation of the tension which results from the twisting or wiring operation.
• the means for heat treatment of the cabled wire (3 - 4) consist of at least one cylindrical cup (7) associated with a return guide (8) to allow hauling of the wires.
• the bucket (7) is brought to a determined temperature and is positively driven in rotation.
• the treatment device has a cooling zone also constituted by the combination of a cylindrical cup (9) and a return guide (10). To the leaving the cooling zone (9) and (10), the wire is wound on a receiving means in the form of a coil (11).
• the cup (7) is associated with heating means making it possible to maintain it at a predetermined temperature.
• these heating means are of the induction type making it possible to maintain the bucket in a predetermined temperature range, for example between 90 ° C. and 240 ° C. approximately.
• the rotation of the bucket (7) is carried out by any known and appropriate means.
• the deflection roller (8) is rotatably mounted.
• the bucket (7) and the deflection roller (8) have spaced grooves (7a) and (8a) formed parallel to their axis of rotation.
• the bucket (9) and the deflection roller (10) have spaced grooves (9a) and (10a) formed parallel to their axis of rotation.
• the cup (9), relating to the cooling zone can be brought to a temperature between 55 ° C and
• the different branches of the buckets (7) and (9) and the deflection rollers (8) and (10) are rounded so as to form grooves.
• different embodiments can be provided at the level for example of their dimensioning.
• the grooves can be the same depth or not.
• the grooves are regularly distributed over the circumference of the bucket and of the deflection roller, without excluding an uneven distribution. Finally, these grooves are mutually parallel or not.
• the wires (3) and (4) are subjected to the action of a roller (12), or other means capable of applying a dye (13) to the wires (3 - 4).
