Definitions

  • the present invention relates to a method for attaching two textile threads and to the device for implementing this method.
  • this method requires a relatively complex mechanism to form the beard on a flat surface on the one hand, then to achieve the interpenetration of the end fibers in the respective deployed zones of the adjacent beards, on the other hand .
  • this process involves, to form the beard, mechanical means for untwisting the thread, pneumatic, electrostatic and thermal means for spreading the fibers in one plane and deploying the area of the base of the fibers and, for carrying out the interpenetration, air injection nozzles directed transversely to the plane of the barbs.
  • Other means are also used as suction through the bearer support plate to cause their adaptation or hot air to promote the plasticity of the fibers.
  • Patent US-4,244,169 and patent application EP 0 053 093 are variants of the previous patent, in which ultrasound is used to undo the wires.
  • the object of the present invention is to remedy, at least partially, the drawbacks of the above-mentioned solutions.
  • the subject of the invention is a method for joining two textile threads as defined by claim 1.
  • the torsion of the superimposed barbs, the fibers of which are intertwined, is transmitted progressively from the two ends to the middle part, limiting the propagation of this torsion by the application to the barbs of opposite transverse forces and whose points of application move towards the middle part as the torsion moves towards this middle part to finally suppress the application of these transverse forces.
  • the subject of the invention is also a device for implementing this method according to claim 3 as well as according to claim 4.
  • This device has other constructive characteristics which will be described later.
  • the wire is untwisted and it is subjected to a slight pulling effect by a pulling clamp which moves axially, which causes a parallelization effect by stretching the barbs.
  • a support member presses the barbs retaining the residual twist of the fibers, so that when the barbs are superimposed, the residual twist of the fibers is recovered with an effect similar to the wiring, in which each element is applied a twist that will maintain the stability of the entire wire. This effect is lost if the fibers of the beards are subjected to a conventional combing effect.
  • the method and the device of the invention make it possible to achieve good reproducibility of the conditions for preparing and joining the beards, since it is dictated only by the shapes of the parts of the mechanism, and the synchronization of most of the sequences follows from the simple bringing together two organs along their respective trajectories.
  • the fibers are constantly subjected to a tension which prevents their relaxation which induces a controlled sliding between the fibers of the two beards.
  • Figures 1 to 4 show the different phases of the process for joining two textile threads, object of the invention
  • Figures 5 to 9 show in a top view the first embodiment of this device and the positions of its mechanisms in the successive phases of the process
  • Figure 10 is an enlarged perspective view of the rotary gripping member of the device
  • Figure 11 is an enlarged perspective view of a detail of the beard support member
  • Figure 12 is a top view of the second embodiment of this device
  • FIG. 13 is a perspective view of a pneumatic chamber for twist and untwist the thread.
  • FIG. 1 represents a first phase of the process in which the previously untwisted wires 1,2 are subjected to axial tensile forces A in order to cause the separation of the barbs 3,4 and the deployment and parallelization of the fibers.
  • said barbs 3,4 are superimposed head to tail by applying opposite transverse forces B in the zone contiguous to the respective ends of said barbs 3,4, as shown in FIG. 2 to immobilize them and retain the individual twist of the fibers and to press them one against the other, simultaneously causing longitudinal sliding of opposite directions of these barbs.
  • the torsion of the superimposed barbs 3,4, the fibers of which are interlaced is transmitted progressively from the two respective ends to the middle part, limiting the propagation of said torsion by application to the barbs 3,4 of said opposite transverse forces B, which move towards the middle part. Finally, when these forces are eliminated, the torsion is transmitted in its entirety, as can be observed in FIG. 4.
  • the device for reattaching the wires 1,2 comprises two gripping pliers 5,6, ends of the wires 1,2, two rotary gripping members 7,8 to induce untwisting respectively a twist of these ends of wires and two support members 9, 10 of the respective barbs, having complementary surfaces.
  • the device further comprises gripping members 11,12 of the ends of the barbs retained by the rotary gripping members 7,8.
  • Figure 10 shows one of these rotary gripping members 7 which comprises in its front end a spiral finger 13 by which, when the clamp rotates in the direction indicated by the arrow E, it drives the wire 1,2 towards the axis of rotation by untwisting it, and when it turns in the direction indicated by arrow F, the thread is twisted away from the axis.
  • the grippers 5,6 of the ends of the wires 1,2 move axially in the direction of the arrows D, which causes a sliding between the fibers of the barbs producing an initial combing of the portion untwisted son.
  • the gripping members 11, 12 pinch the ends of the barbs while retaining the residual twist of the fibers.
  • the support members 9, 10 of the barbs have two complementary surfaces and can move around a center of rotation according to two trajectories which go from respective positions separated from the wires (FIG. 5) to respective positions in which their complementary surfaces are adjacent to each other ( Figure 8).
  • the wires 1,2 are guided on the support members 9,10 by means of guide notches 19,20 at the respective ends of these support members 9,10 as well as at the ends of the corresponding flexible blades 15, 16, as as illustrated in FIG. 11 for the support member 9.
  • the friction between the surfaces in contact promotes the interpenetration of the fibers of the barbs of the two wires.
  • the surfaces of the two flexible blades 15, 16 are covered with rubber or a similar material to facilitate the laying of the barbs and the defibration of the fibers.
  • the support members 9, 10 have respective projections 21, 22 which bear on the elbow supports 17, 18 and cause the beard to be retained over its entire length.
  • a lug 23.24 grasps each of the ends of the opposite beard and wraps it on its own beard, thus beginning the phase of reintroduction of the torsion.
  • rotary gripping members 7,8 are replaced by channels 26,27 of circular section to untwist and twist the threads 1,2.
  • each of the channels 26, 27 open tangentially two conduits 28, 29 respectively 30, 3l, arranged in diametrically opposite positions and intended to be selectively connected to a source of pressurized air to produce in these channels vortices opposite directions.
  • These air vortices are intended to drive the wire arranged coaxially to the channel in a direction to twist it or in the opposite direction to untwist it depending on whether the air is injected through a duct or another.
  • the channels 26, 27 include a longitudinal opening (32) for the introduction and the extraction of the wire, visible in FIG. 13.
