Definitions

  • the invention relates to methods and devices making it possible to join several pairs of ends of yarns of textile assemblies simultaneously, the yarns of these assemblies being multifilaments.
  • an assembly of yarns is called "twisted" when it is made up of several yarns joined together by a single twisting operation.
  • Such assemblies are used, for example, to reinforce articles made of plastics and / or rubber, such articles being, for example, belts, hoses, tire casings.
  • the invention relates in particular to the methods and devices which make it possible to connect two plies by abutting the two pairs of ends of threads of these plies.
  • the object of the invention is to remedy these drawbacks.
  • the invention also relates to the joint assemblies obtained according to the method or with the device in accordance with the invention, as well as to the articles, for example tire casings, reinforced with these assemblies.
  • FIG. 1 shows, seen from above, a device 100 according to the invention, for implementing the method according to the invention.
  • This device 100 makes it possible to connect by their ends two assemblies 1A, 1B which face each other, their axes being practically coincident with the axis xx ', for example horizontal.
  • each assembly 1A, 1B is a twist comprising two threads 10A for the twist 1A and two threads 10B for the twist 1B, these threads 10A or 10B being twisted together in the same direction for the two twists, for example the direction S, each wire 10A, 10B being a multifilament.
  • the device 100 comprises two rotating clamps 2A, 2B, each of these clamps comprising a groove 3, and two spacers 4A, 4B. These clamps and these spacers are known per se and are not described here for the purpose of simplification.
  • the twist 1A is blocked in the groove 3 of the clamp 2A and the twist 1A is opened to locally separate the wires 10A from one another on the spacer 4A.
  • the same is done with the plied 1B and its wires 10B using the clamp 2B and the spacer 4B.
  • the clips 2A and 2B are then rotated in the direction of the arrows F2 and this causes partial twisting of the plies 1A and 1B, which gives the free parts 10A1 of wires 10A, and the free parts 10B1 of wires 10B, these parts being shown in dotted lines in Figure 1.
  • the free parts 10A1, 10B1 thus play the role of free ends intended to be connected.
  • the spacer 4B is arranged between the clamp 2A and the spacer 4A, and, similarly, the spacer 4A is disposed between the clamp 2B and the spacer 4B, following the axis xx '.
  • the device 5 comprises a housing 6 with a cover 7.
  • the housing 6 comprises an upper plate 8 with a gutter 9.
  • the apparatuses 5 are brought into contact with the free parts 10A1, 10B1. These devices 5 are provided with guides 20 which move the parts 10A1, 10B1 so that they are arranged in the gutters 9, and practically parallel to the axis xx ', in the devices 5.
  • the cover 7 is then closed.
  • the device 5 comprises two pairs of scissors 11 situated at the ends of the gutter 9.
  • each wire 10A1, 10B1 We then penetrate the cut and untwisted part of each wire 10A1, 10B1, along the gutter 9, towards the central part of this gutter 9, thanks to the action of a lug 13 which can rotate around its axis 14 , by moving the corresponding wire 10A1, 10B1 away from the other wire 10B1, 10A1, this lug being located at the opposite end of the gutter 9, relative to the cut part of which it causes the displacement.
  • the action of the pins 13 is shown diagrammatically by the arrows F13 in FIG. 1.
  • the guides 20 have only been shown in FIG. 1.
  • the wires 10A1, 10B1 have been assumed to be removed in the central region of the plate 8, so that the holes 16 are visible, and there has been shown only a pair 11 of scissors, only a tube 12 , and that a lug 13, for the purpose of simplification.
  • the holes 16 are arranged in such a way that they can cause on demand, in a known manner, either a non-vortex movement of the air, or a vortex movement of the air during jamming.
  • the wires 10A1, 10B1 are then joined together, in each device 5. These devices are then removed 5, the cut ends of the wires 10A1, 10B1 are removed and the clamps 2A, 2B are rotated in the opposite direction to the arrows F2, so as to twist the wires 10A1 and 10B1 attached together, to obtain a final twist 17, this final twist making the twists appear in the wires 10A1, 10B1 disappear when the pliers 2A, 2B are rotated in the direction of arrows F2.
  • each wire 10A is thus connected to a wire 10B, as previously described .
  • the devices 5 are offset, parallel to the axis xx ', so that the junction zones 15 are offset axially along the axis xx', and therefore following the wires 10A1, 10B1 . These zones 15 therefore do not overlap in the final twist.
  • a final ply 17 is thus obtained which has only very little variation in cross-section at the butting zones, with a significant breaking strength in the butting zone, this force representing at least 70% of that of each of the initial twists 1A, 1B.
  • the devices 5 can be brought close to or away from the wires 10A1, 10B1 by mechanical means capable, for example, of giving them vertical movements. These means are known per se, and, like the means known per se for introducing air into the pipes 12 and the holes 16, they are not shown in the drawing for the purpose of simplification.
  • FIGS. 3 to 8 The various stages of the process are shown diagrammatically in FIGS. 3 to 8.
  • Figure 3 shows the plies 1A, 1B to abut.
  • FIG. 4 represents the two pairs C of wires 10A1, 10B1 before having carried out the untwisting operation.
  • FIG. 5 represents the two pairs C of wires 10A1, 10B1 with for each pair C the junction zone 15 formed by the untwisted part of these wires.
  • FIG. 6 represents the two pairs C of wires 10A1, 10B1 after scrambling the zones 15, in order to join these wires together, the filaments of these wires being entangled between them without swirling movement of the air.
  • FIG. 7 represents another variant of the step shown in FIG. 6, in which the scrambling is carried out with swirling movements of the air from so as to have, for each zone 15, a helical structure, with an S-winding and a Z-winding.
  • FIG. 8 represents the final twist 17.
  • the strength of resistance to rupture in the jointing zone is 130 N (i.e. 72% of the initial force, the reduction in this force therefore being only 28%), and the increase in section in the jointing area is 50% compared to the initial section of each ply.
  • the conventional abutment techniques practically cause the section to be doubled, and a reduction in the tensile strength of breakage of approximately 60%, in the abutment zone.
