Definitions

  • the present invention relates to the field of carpet yarn processing systems and more particularly to the field of yarn displacement management devices in these processing systems.
  • the differences in output by the coils of recovery are of the order of 200 meters or nearly 1% difference.
  • the object of the present invention is to overcome these disadvantages by proposing a device that makes it possible to reduce or even eliminate these flux variations of treated son to obtain homogeneity, on the one hand, in the unwinding and on the other hand, in the recovery of the wire by the coils while being adaptable on existing son processing systems.
  • the invention thus relates to a device for guiding a strand of at least two son on a conveyor structure, characterized in that the device involves a mechanism for generating false twists between the at least two son of the strand.
  • the invention also relates to a carpet son treatment system, characterized in that the system comprises in particular a device for guiding a strand of at least one wire on a conveyor structure according to the invention, this guiding device. a strand being positioned between a wire or strand feed mechanism and a strand removal mechanism on a conveyor structure.
  • the invention also relates to a method of guiding a strand of at least two son on a conveyor structure characterized in that it comprises at least one step of generating a false torsion of the strand prior to the step laying the strand on the conveyor structure.
  • the present invention relates to a device for guiding a strand 1 of at least two wires on a conveyor structure, characterized in that the device involves a mechanism 2 for generating false twists between the at least two wires of the strand 1
  • the generation of false twists between the wires of the strand 1 allows a modification along the strand 1 of the position of these strands at a section of the strand 1.
  • This change of position of the strands thanks to these successive false twists makes it possible to to obtain homogeneity in the distribution of each of the yarns within the strand 1.
  • the same yarn will be positioned successively and cyclically at different positions of the strand 1 during the formation of this strand 1 of son from a feed mechanism comprising a plurality of son coils.
  • each of the wires By virtue of this homogenized distribution of each of the wires along the strand 1, the length variations of each of the wires due to their respective positions in the strand 1 when this strand 1 is deposited in loops on a displacement structure such as a transport band, are reduced or even eliminated.
  • each of the wires is brought and guided, thanks to several false twists, to be positioned successively and alternately with different positions inside or on the periphery of the strand 1.
  • the mechanism 2 for generating false twists is positioned at a portion of the son of the strand 1 which has an axial tension sufficiently low for a torsion can be performed on its structure. Indeed, in case of excessive axial tension, a twist of the strand 1 could be at the origin of a risk of rupture of one or more son of the strand 1.
  • the mechanism 2 for generating false twists is positioned downstream of a mechanism for regulating the voltage of the strand 1 supply wires. son is upstream of the voltage regulation mechanism, between the supply coils and this regulation mechanism which pulls, upstream, the son from their coils to supply, downstream, the formation of the strand 1.
  • this voltage regulation mechanism is achieved by one or more rollers rotatably mounted around their respective axes.
  • the son which feed the strand 1 are then arranged on all or part of the periphery of these rollers to be driven in displacement by these rollers.
  • the axis of these rollers is thus positioned substantially perpendicular to the axis of displacement of the different son of supply of the strand 1.
  • the rollers of the mechanism of regulation of the tension also taking part in the training of the wires intended to form the strand 1, the tension is then exerted on these threads only upstream of this mechanism during unwinding of the supply coils; this tension being released downstream of these rollers at the mechanism 2 for generating false twists.
  • the disk 3 comprises a number of perforations of the same order of magnitude as the number of wires that make up the strand 1. A wire or a group of wires is then arranged so as to pass through a respective perforation which will guide this thread or group of threads to position it in the strand 1 being formed. The pendular rotation of the disc 3 thus allows the regular generation of false twists along the strand 1.
  • the carrier structure 4 of the disc 3 can thus be formed by an annular structure which surrounds the entire disc 3.
  • the disk 3 is rotatably mounted on the supporting structure 4 by means of a ball bearing 6.
  • This bearing 6 thus has the advantage of optimizing the reduction of friction between the disk 3 and the annular structure 4 which carries the disk 3.
  • the structure 4 which carries the disc 3 simply comprises a portion in an arc and intended to interact with the peripheral edge of the disc 3.
  • the peripheral edge of the disc 3 is then mounted sliding at the level of this portion in an arc while allowing the positioning of the disc 3 in a plane substantially perpendicular to the axis of movement of the strand 2.
  • the transmission of the pendular rotational movement between the actuating motor 5 and the rotating disc 3 involves at least one driving belt that can be notched. At least a portion of this drive belt is thus positioned on at least a portion of the periphery of the disk 3; another portion of this belt being driven by an element actuated by the actuating motor.
  • the transmission of the pendular rotational movement between the actuating motor 5 and the rotating disc 3 involves at least one gear of the gear type cooperating with a toothed structure disposed on the periphery of the rotating disc 3.
  • the actuating motor 5 is associated with a control means allowing management of the amplitude and / or the speed of the rotational rotation of the rotating disc 3.
  • the motor 5 for actuating the rotation of the disc 3 the latter generates pendulum rotations of at least a quarter turn of the disc 3 in opposite directions.
  • the latter According to a second embodiment of the motor 5 for actuating the rotation of the disk 3, the latter generates pendular rotations of at least one half-turn of the disk 3 in opposite directions.
  • the latter According to a third embodiment of the motor 5 for actuating the rotation of the disk 3, the latter generates pendular rotations of at least one complete revolution of the disk 3 in opposite directions.
  • the twists operated on the strand 1 son are the result of friction and deformation of the entire strand 1 already formed and not a modification of the distribution of the yarns during the very step of the deformation of the strand 1.
  • the twists operated on the strand 1 son are also, as for the second alternative mode, the result of friction and deformation of the whole of the already formed strand 1 .
  • the invention also relates to a system for treating carpet yarns, characterized in that the system comprises in particular a device for guiding a strand 1 of at least one yarn on a conveyor structure according to the invention. guiding a strand 1 being positioned between a feed mechanism son or strand 1 and a mechanism for removing the strand 1 on a conveyor structure.
  • the invention also relates to a method of guiding a strand 1 of at least two wires on a conveyor structure characterized in that it comprises at least one step of generating at least one false twist of the strand 1 prior to the laying step of the strand 1 on the conveyor structure.
