Definitions

  • the present invention relates to the field of son management mechanisms in a processing system and more particularly to the field of son management mechanisms upstream of a heat treatment interface.
  • the present invention aims to overcome these disadvantages by proposing a solution that eliminates this problem of homogeneity between the different son treated.
  • the subject of the invention is thus a device for managing yarns in a yarn processing line downstream of a curling box and upstream of a means for thermal fixation of the crimp, said device comprising a fixed support, inlet of the curling box being formed by one or more crimping rolls for feeding at least one wire into the curling box, characterized in that the device comprises at least one axial drum positioned upstream of the fastening means thermal, the drum being traversed by a wire in the curling box and mounted on the fixed support of the device so as to operate a substantially axial rotation for generating at least one false twist to the treated son.
  • the invention also relates to a method for managing yarns in a yarn processing line, characterized in that it comprises a step of generating at least one false twist of the yarns during the passage of the yarns in a drum, prior to a step of thermal fixing of the son.
  • the present invention relates to a device 1 for managing yarns in a line for processing yarns downstream of a curling box 2 and upstream of a means for thermal fixation of the curl, said device 1 comprising a fixed support 3 , the inlet of the curling box 2 being formed by one or more crimping rolls 7 for feeding at least one thread into the curling box 2, characterized in that the device 1 comprises at least one axial drum 4 positioned upstream of the thermal fixing means, the drum 4 being traversed by a wire in the curling box 2 and mounted on the fixed support 3 of the device 1 so as to operate a substantially axial rotation to generate at least one false twist to treated son.
  • the son In their crossing of the axial drum 4, the son are without tension.
  • the latch by rotation of the drum 4 allows a change in the distribution of the portion of the son present in the drum within the son strand that joins them.
  • This modification of the distribution of the son by the drum 4 in the treatment line thus allows a reorganization of the son within of the strand over their entire respective length.
  • the generation of this false twist allows different portions of the same wire to be arranged differently along the treatment line, for example on the conveyor belt, and in particular at each of the thread processing stages. with the other wires of the strand.
  • the invention also relates to a method for managing yarns in a yarn processing line, characterized in that it comprises a step of generating at least one false twist of the yarns during the passage of the yarns in a drum, prior to a heat fixing step son.
  • the wire management device 1 is characterized in that the drum 4 is mounted on the fixed support 3 of the device 1 and arranged to operate a rotary pendular movement around the axis of the drum 4.
  • the drum 4 is associated with a drive means 5 for driving in rotation.
  • This association can be achieved by any known mechanism for example a drive belt or a gear.
  • the axis of rotation of the drum 4 is oriented along a substantially horizontal axis. According to this construction, the displacement of the son through the drum 4 is generated either upstream by the arrival of the son by the feeding rack which operates a stuffing in the drum 4 pendulum swing, or downstream by pulling the son deposited on a drive means, for example a treadmill, or a combination of these two phenomena.
  • the pendulum swing of the drum 4 makes it possible to limit or eliminate the tensions on the wires when they are pulled by the drive means downstream of the drum 4.
  • the axis of rotation of the drum 4 is oriented along an axis providing an inclination with respect to a horizontal axis.
  • this inclination is made from a high point upstream of the drum 4 to a low point downstream of the drum 4.
  • Such inclination makes it easier to move the threads through the drum 4 from a high point to a low point by taking advantage of of the gravity of the wires which constitute the strand which crosses the drum 4.
  • the invention also relates more specifically to the drum 4 adapted to allow the generation of a false twist on the various son passing through it.
  • the drum 4 of the invention has a substantially cylindrical body 4a with a circular or oval section.
  • this shape could be of polygonal section, for example pentagonal, hexagonal or octagonal.
  • the drum 4 of the invention is characterized in that the inner surface 4c of the body 4a of the drum 4 has a substantially conical shape.
  • the conical arrangement is preferably arranged from a restricted upstream opening to a wide downstream opening. Such an arrangement makes it possible to perform a facilitated installation at the outlet of the drum 4, for example at a precise point of a drive means such as a conveyor belt.
  • the body 4a of the drum 4 has a substantially axial tubular shape.
  • this axis of the body 4a of the drum 4 may be different from the axis of rotation of the drum 4 during its operation for the generation of false twists.
  • the axis of rotation of the drum 4 coincides with the axis of the body 4a of the drum 4.
  • the drum 4 is characterized in that it comprises at least one gripping surface 6 made by at least one relief of the inner surface in a section perpendicular to the axis of the drum 4.
  • This surface d 6 grip participates in the rotational training of the son to allow to generate false twists, together with the rotation of the drum 4.
  • the grip surface 6 must however allow the sliding of the son through the body 4a of the drum 4.
  • this gripping surface 6 is made continuously along the length of the inner surface 4c of the drum 4 between the upstream opening 4d and the downstream opening 4e.
  • This gripping surface 6 can also be continuous or discontinuous along the periphery of the inner surface 4c of the drum 4.
  • this gripping surface 6 is made by a rough surface, for example of emery-type deposited on all or part of the inner surface 4c of the body 4a of the drum 4.
  • the drum 4 is characterized in that it comprises at least one gripping surface 6 made by at least one relief 6a of the inner surface 4c.
  • This relief 6a which exceeds the inner surface 4c allows a rotation drive of the various son with the drum 4 at the portion of son that passes through the drum 4.
  • This relief 6a may be specific to a training in rotation of the threads according to a particular direction of rotation of the drum 4.
  • the relief 6a which forms this gripping surface 6 in the drum 4 is arranged so as to achieve a continuous relief 6a along the length of the inner surface 4c of the drum 4 between the upstream opening 4d and the opening swallows 4th.
  • the relief 6a is constructed to have a variation of its height between a greater height at a point near the upstream opening 4d and a smaller height at a nearby point. from the opening swallows 4th.
  • the relief 6a comprises an axis of symmetry S which intersects the axis of rotation of the drum 4 in a section perpendicular to the axis of the drum structure 4.
  • the embodiment a relief 6a comprising such a symmetry makes it possible to operate a rotation of the various son by the drum 4 which is identical in both directions of rotation of the drum 4. Such a construction thus facilitates the generation of homogeneous false twists at the level different wires moving in the drum 4.
  • the inner surface 4c of the body 4a of the drum 4 comprises at least two gripping surfaces 6 of at least one wire.
  • the multiplication of the number of gripping surfaces 6 of the thread inside the drum 4 makes it possible to optimize the rotation of the threads with the rocker of the drum 4.
  • the drum 4 of the invention is adapted to be integrated in a son of management device 1 according to the invention.
