Definitions

  • the invention relates to a guide device for weft insertion elements for weaving machines, in particular rapier projectile weaving machines, with longitudinally alternating guide supports and guide hooks which form a guide channel for the weft insertion element, the guide consisting of a longer leg adjacent to the reed, a shorter one, from the reed removed leg and part of the guide hook is formed.
  • the invention has for its object to provide a guide device of the type defined in the introduction, in which a crossing of a warp thread of the type mentioned above is not possible and thus its overextension is avoided.
  • This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • a drawer 1 carries a projectile guide device 2, which consists of a number of guide supports 3 and guide hooks 4, which are cast in a block 5.
  • the guide supports and guide hooks alternate with one another in the longitudinal direction of the guide device and each form a complementary guide element 6 in pairs.
  • the guide support 3 and the guide hooks 4 together form a guide channel 8 for a projectile 9, which is a weft thread 10 drags with him.
  • the drawer 1 with the guide device 2 is located before the weft thread 10 stops by a reed 11 in a shed 12, which is formed by the warp threads 13 and 14.
  • the drawer 1 moves the projectile guide device 2 between the fully drawn and the dashed position 2 '.
  • the contours of a guide support 15a or a guide hook 15b of a guide element 15 are first drawn in with dash-dotted lines in FIG. 2.
  • the guide support 15a consists of a longer leg 15c closer to the reed and a shorter leg 15d located farther from the reed, with a valley 15e as a transition between the two.
  • the projectile is supported in three ways: on the inside of the longer leg 15c, on the shorter leg 15d and on the upper inner edge of the guide hook 15b.
  • the guide hook 15b is mainly characterized by a long, narrow neck 15f, so that a large clear width 16 remains within the guide element.
  • An adjacent guide element is designated 17.
  • a warp thread 19 In a lane 18 of the guide element 15 there is a warp thread 19, in a lane 20 between the guide element 15 and the next guide element 17 there is a warp thread 21.
  • the warp thread 21 from the alley 20 hooks behind the shorter leg 15d of the guide support 15a and passes through the valley 15e into the alley 18, where the correctly running warp thread 19 is located.
  • the deviating warp thread is shown in dash-dot lines and designated 21 '. This leads to an undesirable overstretching of the different warp thread.
  • the shorter leg 15d of the guide support 15a is removed from each guide tooth 15, so that only one single-leg guide support 15c remains for the projectile near the reed.
  • the neck 15f of the guide hook 15b is widened towards the guide channel 8 and has a support surface 22 for the projectile. Both measures prevent the warp thread from being overstretched when it jumps into an adjacent alley.
