Definitions

  • the present invention relates to an improved machine allowing continuous twisting or cabling of follow-up wires additional heat treatment.
  • Such machines used in particular for making threads for carpets have been proposed for a very long time as it emerges in particular FR-A-1 455 499 and US-A-3 525 205. It was also proposed to use such machines to process synthetic yarns partially drawn, the drawing being carried out at the level of the double spindle torsion as shown in FR-A-2 414 568.
  • the wire is kept in the relaxed state for heat treatment and during the cooling phase before winding.
  • the thread is received on a mobile relaxation where it forms a reserve, the speed of reception of the whole winding being regulated so that the quantity of thread placed in reserve is maintained between two predetermined minimum and maximum values.
  • the cooled path of the wire is produced by rotating guide elements interposed between the oven outlet 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 on the other and are offset laterally with respect to the fixing furnace.
  • each working position of a machine comprises a double twist spindle or conventional wiring (1) allowing either twisting of conventional way, 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 per rotation of said pin.
  • it When used to perform an operation of direct wiring, it has a hollow barrel and a second wire is brought to the across the latter to be joined to the wire (3) carried by the spindle at level of a wiring head (4) which is arranged in the extension of the axis of said spindle (1).
  • This processing zone includes, if one follows the path of the wire, a positive type deliverer (5).
  • This deliverer is advantageously of the type illustrated in Figures 6 and 7 and essentially consists of a capstan type assembly (6) and pressure cylinder (7), which, in association with a grooved cylinder (20) (see FIG. 7), makes it possible to obtain hauling of the wire (3) (or of the wired wire) and therefore very high accuracy in the speed of call of said wire as well that a cancellation of the tension which results from the twisting operation or wiring.
  • the deliverer (5) is arranged at the inlet of the treatment furnace thermal proper (8), oven which is arranged vertically or substantially vertically as illustrated in the appended figures where it forms an angle of about five degrees from the vertical.
  • This oven is a conventional oven of the type used on the texturing material by false twist.
  • a call and forwarding system designated by the general reference (10) 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 system call and forwarding consists of a set of type "thread regulator” or “overspeed deliverer”, comprising two cups (20,21) between which the wire passes, positively driven in rotation, preferably by an individual motor (22) as illustrated in Figures 8 and 9.
  • a deliverer allows the training of the wire by sliding and calling it at a higher speed than scrolling normal. It allows, depending on the variations of the wire calling speed, automatically obtain self-regulation of the output voltage of the deliverer, this voltage being maintained at a very low value.
  • the call and forwarding system (10) may consist of a pressure roller type positive deliverer.
  • the wire (3) goes to the surface of a cylindrical guide (23) also rotated 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) As said previously, pass a second time inside the oven (8) while being kept under minimal tension.
  • the vertical position or substantially vertical oven (8) allows to benefit from the effect of gravity so that the wire remains straight.
  • the wire is preferably transferred by through a guide trough (26) to means allowing to ensure the cooling of the wire in the relaxed state.
  • the guide chute (26) has a V-shaped section.
  • the means making it possible to cool the wire in the relaxed state consist of a conveyor belt (11), arranged horizontally below the oven (8).
  • This mat can be either individual for each working position, is common to all positions and then extends across the width of the loom.
  • Such a mat (11) is moved at a speed which can be understood between 0.3 and 3 m / min and allows an accumulation of the wire allowing cooling in the fully relaxed state. So, as shown in Figure 5, the wire (3) is deposited on the carpet conveyor in the form of turns (27). The distance A between the end of the guide trough (26) and the surface of the mat (11) conditions the formation of turns (27), the direction of formation of the turn being opposite to direction of twist.
  • the wire (3) After relaxation, the wire (3) passes over a recovery system produced by a tensioner (12) to then be brought by conventional winding means (13).
  • the reception speed of the winding assembly (13) is regulated by through a reserve detector (28) which makes it possible to carry out a acceleration for a given time so that the wire (3) put in reserve in the form of a whorl is kept between two minimum values 1 and predetermined maximum L, for example between 150 mm and 350 mm length.
  • the wire cooling is carried out by passing it around elements deflection consisting of free rotating rollers (14,15), the wire being brought to the winding system (13) via a hysteresis brake (16) adjusted so that said wire (3) is held upstream under tension minimal.
  • Such a wire is produced on the machine according to the invention such 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) from an additional support mounted on the frame of the machine and which crosses the hollow barrel of the spindle.
  • Such a procedure makes it possible to obtain a wire which can be used for making carpets which, compared to articles made from yarn conventional, has an improved appearance and feel.
