Definitions

  • the present invention relates to weaving looms in which each pick is constituted by a length of thread which is taken, by a thrown weft pass or "false shuttle" member, from one or the other of two reserves of fixed frames provided laterally on the frame of the loom.
  • the present invention intends to remedy, and this by providing the false shuttle with an improved wire cutter device, arranged so as to positively cut the wire in line with the usual lateral clamp.
  • the device according to the invention comprises, mounted on the one hand on the weft or false shuttle member and on the other hand laterally on either side of the loom, at least one cutting member, at least one member guide formed by two metal plates held elastically applied one against the other and capable of moving apart to allow passage to the aforementioned cutting member, and means for vertically moving each of said members which are fixed laterally on the loom to bring it on the path of movement of that of the organs which is mounted on the false shuttle, when the latter enters the crowd.
  • this false shuttle 1 is equipped with a thread clamping mechanism, comprising a movable jaw 2 (fig. 3) articulated longitudinally at 3 on the false shuttle, this jaw 2 being provided with a upper operating tab 4 and a heel 5 associated with a spring 5 a .
  • the latter ensures the elastic maintenance of the movable jaw 2 against a fixed jaw 6, thereby pinching the weft thread 7 deflected laterally by a lug 8, a thread which is released only by action against the tab 4.
  • jaws 2 and 6 are offset laterally on the side of the false shuttle 1 which is turned opposite the comb of the loom, and it is on the free side of the fixed jaw 6 that one of the members of the wire cutter device according to the invention is mounted.
  • a guide member which has been referenced 9 and which comprises a housing 10 with a U-shaped cross section, fixed laterally against the fixed jaw 6 of any suitably, for example using screws such as 11.
  • this housing 10 are housed two metal plates 12 which are held elastically applied one against the other by means of shims 13 made of a deformable material ( rubber or synthetic material).
  • shims 13 made of a deformable material ( rubber or synthetic material).
  • the plates 12, which protrude beyond the vertical edges of the housing 9, are profiled in the manner illustrated in FIG. 4, to comprise on the one hand an upper transverse sharp edge for severing 12 has disposed at each of said edges on the other of the rounded profile ends 12 b forming funnels.
  • the thread-cutting device also comprises, on each of the two sides of the loom, a cutting member formed by a blade 14 (fig. 3) carried by a die 15 suitably guided and made integral with a vertical rod 16 which is animated by '' a vertical reciprocating movement, so that said blade comes to be disposed either on the path of the housing 10 when the false shuttle 1 enters the crowd on both sides of the loom, or above this journey when said false shuttle leaves this crowd.
  • a cutting member formed by a blade 14 (fig. 3) carried by a die 15 suitably guided and made integral with a vertical rod 16 which is animated by '' a vertical reciprocating movement, so that said blade comes to be disposed either on the path of the housing 10 when the false shuttle 1 enters the crowd on both sides of the loom, or above this journey when said false shuttle leaves this crowd.
  • a cutting member formed by a blade 14 (fig. 3) carried by a die 15 suitably guided and made integral with a vertical rod 16 which is animated by '' a vertical reciproc
  • the edge of the blade 14 is turned towards the outside of the loom, so that when the false shuttle 1 has taken and pinched the thread of the penultimate pick (that is to say of the last pick which came out on the same side considered of the loom) and immediately before it enters the crowd again to deposit a new pick there, the blade 14, lowered by the rod 16, engages in the front funnel 12 b of the plates 12 (fig. 4) which move apart by means of momentary elastic deformation of the shims 13. The wire 7 is then applied by the blade 14 against the upper edge 12 a and is therefore sectioned (fig. 5) , like by scissors.
  • the plates 12 gradually move apart allowing the blade 14 to exit the housing 10 through the rear end thereof (fig. 6), so that this blade can then rise under the effect of the return of the rod 16 upwards.
