Definitions
- the present invention relates to an improved machine making it possible to continuously twist or wire wires followed by additional heat treatment.
- a heat treatment oven arranged either vertically (FR 1 455 499) or horizontally (US-A-3 525 205), followed by a cooling zone and; . means for winding the treated yarn.
- the wire is kept in the relaxed state during the heat treatment and during the cooling phase before winding.
- the machines covered by the aforementioned patents relate to the twisting of a single wire, it has long been proposed to use similar machines to carry out direct wiring operations as is apparent from US-A- 3 820 316. To do this, in such a case, the wire coming from the winding mounted on the spindle is associated with a second wire coming from a second coil mounted fixed on the frame of the machine, and which is brought, through the barrel of said pin, to a wiring head arranged in the extension of the latter.
- the machine according to the invention is of the type comprising, in a manner similar to the teachings of US Pat. No. 3,525,205, a central frame supporting a plurality of identical working positions each comprising:
- the machine according to the invention which makes it possible to carry out both a twisting operation and a direct wiring operation, is characterized in that:
- the heating means are constituted by a rectilinear oven arranged vertically or substantially vertically;
- the wire goes back and forth inside said oven and is introduced and extracted from the latter by its lower part, a call and return system for said wire being provided in the upper part;
- Means are provided to maintain the wire under a minimum tension during the cooling phase and to deliver it to the winding means.
- the yarn is received on a mobile relaxation mat where it forms a reserve, the speed of reception of the winding assembly being regulated so that the quantity of wire placed in reserve is kept between two predetermined minimum and maximum values.
- the cooled path of the wire is produced by means of rotary guide elements interposed between the outlet of the oven and a tensioner positioned upstream and in the plane of symmetry of the winding system.
- the double twist spindle and the winding system are advantageously positioned one above the other and are offset laterally relative to the fixing furnace.
- FIGS. 1 and 2 are respectively side and front views of a working position of a machine produced according to the invention
- Figures 3 and 4 are views similar to Figures 1 and 2 of a variant concerning the manner in which the cooling of the wire is carried out on a machine according to the invention
- FIG. 5 is a detail view, schematic of the means used to ensure the relaxation of the wire during its cooling phase in the embodiment illustrated in Figures 1 and 2;
- FIG. 6 and 7 are partial views showing side view ( Figure 6) and front view ( Figure 7) the structure of the call device disposed at the entrance of the oven;
- FIGS 8 and 9 are partial views, enlarged showing the structure seen from the side and front of an embodiment of the call device provided in the upper part of the oven;
- each working position of a machine according to the invention comprises a double twist or conventional wiring spindle (1) allowing either twisting in a conventional manner, or a direct wiring operation.
- this spindle is driven by an individual motor and therefore supports a coil (2) of the wire (3) to be treated.
- the double twist spindle (1) makes it possible to communicate to the wire (3) two turns of twist by rotation of said spindle.
- the treatment zone proper Downstream of the double twist or direct wiring assembly (1), the treatment zone proper is arranged.
- This processing zone comprises, if the path of the wire is followed, a deliverer (5) of the positive type.
- This deliverer is advantageously of the type illustrated in Figures 6 and 7 and consists essentially of a set of capstan type (6) and pressure cylinder (7), which, in association with a grooved cylinder (20) (see Figure 7 ), makes it possible to obtain a hauling of the wire (3) (or of the cabled wire), and therefore a very high precision in the speed of call of said wire as well as a cancellation of the tension which results from the twisting operation. or wiring.
- the wire (3) has not been shown in Figure 2 between the output of the spindle (2) and the deliverer (5).
- the pressing cylinder (7) is shown in fine lines in the non-working position in FIG. 6.
- the deliverer (5) is arranged at the inlet of the actual heat treatment oven (8), an oven which is arranged vertically or substantially vertically as illustrated in the appended figures where it forms an angle of approximately five degrees with respect to the vertical .
- This oven is a conventional oven of the type used on false twist texturing equipment.
- a call and forwarding system designated by the general reference (0) and which allows the wire to make a second pass inside the oven (8). during which it is kept in the fully relaxed state.
- this call and forwarding system (10) is constituted by an assembly of the "wire tensioner” or “overspeed deliverer” type, comprising two cups (20,21) between which the wire passes, positively driven in rotation, preferably by an individual motor (22) as illustrated in FIGS. 8 and 9.
- a deliverer allows the wire to be driven by sliding and calls it at a higher speed normal scrolling. It allows, as a function of the variations in the call speed of the wire, to automatically obtain self-regulation of the voltage at the output of the deliverer, this voltage being maintained at a very low value.
- the call and forwarding system (10) can be constituted by a positive delivery device of the pressure roller type.
- the wire (3) passes over the surface of a cylindrical guide (23) also driven in rotation by a motor (22), the roller (24) subjected to the action of a return element ( 25) (spring) exerting pressure on the wire.
- the wire (3) passes a second time inside the oven (8) while being kept under vertical tension.
- the vertical or substantially vertical position of the oven (8) makes it possible to benefit from the gravity effect so that the wire remains well rectilinear.
- the wire is preferably transferred via a guide chute (26) to means making it possible to cool the wire in the relaxed state.
- the guide chute (26) has an N-shaped section.
- the means making it possible to cool the wire in the relaxed state consist of a relaxation mat (11), arranged horizontally below the oven ( 8).
- This mat can either be individual for each working position, or common to all positions and then extends over the entire width of the loom.
- Such a mat (11) is moved at a speed which can be between 0.3 and 3 m / min and makes it possible to produce an accumulation of the wire allowing cooling in the fully relaxed state.
- the wire (3) is deposited on the conveyor belt in the form of turns (27).
- the distance A between the end of the guide trough (26) and the surface of the belt (11) conditions the formation of the turns (27), the direction of formation of the turn being opposite to the direction of torsion.
- the thread (3) passes over a recovery system (12) to then be brought by means of conventional winding (13).
- the speed of reception of the winding assembly (13) is regulated by means of a reserve detector (20) which makes it possible to carry out an acceleration for a given time so that the wire (3) placed in reserve in the form of the turn is maintained between two predetermined minimum 1 and maximum L values, for example between 150 mm and 350 mm in length.
- the wire is cooled by passing it around return elements made up of free rotating rollers (14, 15), the wire being brought to the return system ( 13) by means of a hysteresis brake (16) adjusted so that said wire (3) is held upstream under a minimum tension.
- Such a wire is produced on the machine according to the invention as illustrated in FIGS. 1 and 2, the wire (3) coming from the coil carried by the pin being associated with the wiring point (4) with a second wire (not shown) coming from an additional support mounted on the machine frame and which crosses the hollow shaft of the spindle.
- the machine settings for making such a wired wire are as follows:
- Example 2 Such a procedure makes it possible to obtain a yarn usable for the production of carpets which, compared to articles produced from conventional yarns, has an improved appearance and feel.
- Example 2
- This wire is produced on a machine according to the invention as illustrated in FIGS. 3 and 4, and this under the following conditions:
