Definitions

  • the present invention relates to an improved machine making it possible to produce wires using the so-called “self-twisting” technique.
  • the technique which consists in making self-twisted yarns has been known for a long time and generally consists in bringing together at least two threads, at least one of which has an alternating twist along its length so that, when they are put side by side, they wrap around each other.
  • the two wires are with alternating torsion, the torsion zones of the same direction being either in phase, or slightly out of phase, with respect to each other.
  • a device for calling the self-twisted thread is disposed between the winding means and the zone where the self-twisting of the two threads is carried out on one another.
  • this vertical arrangement of the processing members and this path from the top to the bottom of the material makes it possible not only to obtain regular self-twisted yarns, but also to increase production speeds.
  • self-twisted yarns were produced according to the technique described in USP 4 033 102, that is to say self-twisted yarns of which at least one of the components has a core.
  • the vertical arrangement of the stretch sleeves and the biased incorporation of the core allowed better centering of said core in the middle of the fibers and avoided the use of additional means (blowing duct) to bring the core to inside the fiber wick.
  • the positive deliverer of the wire delivering the material is located near this creel.
  • the deliverer spaced from the processing means will be designated by the expression “supply deliverer” and that located upstream of the means making it possible to communicate the alternating twist by the expression “self-twisting provider”.
  • the self-twisting deliverer is constituted by the last pair of cylinders of a drawing system of a wick, this drawing train being preferably arranged vertically above the processing members, but possibly also having another orientation.
  • the wicks are supplied from coils held in the upper part of the frame.
  • the machine according to the invention comprises a plurality of identical working positions arranged side by side on a support frame.
  • the wire feeders 1 are separated from the wire processing means so as to form a passage area 3 for the operator.
  • the wire 2 comes from coils stored on a conventional creel 5 disposed at the same level and spaced from the processing means.
  • the creel 5 could be located on a platform so as to free up the space on the ground.
  • the wire processing means are grouped together on a common frame 6, shown in dotted lines in FIG. 1. These processing means are constituted from top to bottom by a self-twisting deliverer 7 making it possible to deliver two wires 2 in parallel.
  • conventional means 8 are arranged below this release 7 and communicate an alternating twist to the two treated wires 2.
  • a second deliverer 9 allows the self-twisted yarn produced to be called up, which is then returned conventionally at 10.
  • a deliverer formed by a continuous shaft 11 extending over the entire width of the machine will be used, for example, on which rollers 12, 13 support the wires 2 individually.
  • the means 8 making it possible to communicate an alternating twist to the wire consist, in the present case, of an assembly comprising a false twist member 14, formed for example of crossed belts simultaneously treating the two wires 2.
  • the alternating twist is obtained by varying the length of the twist rise between the spindle 14 and the self-twisting deliverer 7 for example by means of a conventional intermittent deliverer 15.
  • the two elementary wires 2 having received an alternating twist are assembled by simple downstream twisting of spindle 14, their junction being obtained by means of a guide 16.
  • the caller 9 for the formed wire can also consist of a continuous shaft 17, on which support individual conventional sleeves 18.
  • the winding 10 is carried out in a conventional manner, for example by tangential drive. It is obvious that one could also carry out a winding by means of a pin with ring and cursor, if for example one wishes to twist the wire formed.
  • Such an installation makes it possible to easily treat any type of yarn, whether it is based on continuous filaments or yarns of fibers.
  • cold drawing can be performed by adjusting the respective speeds of the feeder 1 and the self-twist 7.
  • the two wires 2 which must be self-twisted are brought in parallel but nevertheless undergo a slight change of direction at the exit of the self-twisting deliverer 11, for example by means of guides 30, 31 making it possible to reduce their spacing, one could of course envisage keeping the spacing between these wires constant throughout the treatment, as shown in dashed lines in FIG. 2.
  • the guides 30, 31 could possibly be deleted.
  • the deliverer 1 could be arranged directly above and in the same vertical plane as the self-twisting deliverer 7 and that the means 8 for communicating the alternating torsion to the sons.
  • Figures 3, 4, 5, 6 and 7 illustrate the adaptations which can be carried out in a simple manner on such a type of machine.
  • Figures 3 and 4 show the adaptation of this machine for the production of self-twisted core wires.
  • the frame 6 there is at the upper part of the frame 6 a supply 19 of wicks of fibers 20.
  • the self-twisting deliverer 7 is constituted by the last pair of cylinders of a conventional stretching system such as for example a double sleeve system 21.
  • the core wires consist of the wires 2 coming from the creel 5, these wires being incorporated into the wick 20 immediately upstream of the. stretching deliverer 7, a condenser 22 can be provided in this zone to facilitate the introduction of the core into the wick.
  • guides 30, 31 may be provided at the outlet of the self-twisting deliverer 7 to reduce the spacing between the wires in the area where they undergo the operation allowing them to communicate an alternating twist. As before, it could be envisaged to keep the distance between the wires constant over the entire length of the treatment.
  • FIG. 5 illustrates a variant in which a heat treatment member 23, such as an oven, is arranged in the upper part of the machine.
  • This oven 23 which can be an open oven or a closed oven, is preferably arranged horizontally or slightly at an angle in the upper part of the machine.
  • a complementary deliverer 24 shown in dotted lines in this FIG. 5, is provided at the outlet of the oven 23 and makes it possible to carry out a hot drawing, in cooperation with the feeder 1.
  • This type of material can also be equipped with a wick feed system 20.
  • the inclination of the oven 23 is such that the wire 2 is brought obliquely upstream of the last pair of rollers of the train. stretch forming the self-twisting deliverer 7.
  • FIG. 6 illustrates a variant in which a texturing operation is carried out by false twist between the feeder 1 and the self-twisting unit 7.
  • this texturing operation can be combined with a simultaneous drawing of the wire 2.
  • a cooling plate 25 can be provided between the spindle 26 and the oven 23.
  • the processing members are mounted symmetrically on a common frame.
  • FIG. 7 illustrates a variant of a machine in which the feeder 1, which in accordance with the invention is separated from the treatment members, is arranged at a lower level so as to be able to adapt between this deliverer and the control members processing, a texturing installation, for example by false twisting, also comprising an oven 23, a cooling path 25 and a spindle 26.
  • the passage zone 3 for the operator is located between the texturing zone and the treatment zone allowing the self-twisted yarn to be obtained .
  • a system for feeding a wick of fibers can be provided in the upper part of the machine.
  • the machine includes means for detecting breakage and stopping for each position, and can be equipped with any conventional means allowing the wire to be treated correctly. , for example voltage regulators, suction systems allowing correct launches and / or eliminating the down that might escape during the treatment.
