Definitions

  • the invention relates to a guide tooth for forming a weft insertion channel of a weaving machine, with a free leg that divides the warp threads when entering the shed.
  • the object of the invention is to create a guide tooth which is particularly improved in this regard, with which it should be possible in particular to process knot yarns in the chain.
  • the invention consists in that the free leg has a straight outer edge which runs parallel to the warp threads to be divided when they come into contact with them.
  • the weaving machine contains a drawer 2 pivoted back and forth according to arrow 1, which carries a reed 3 and a number of guide teeth 4.
  • a weft thread 6 is inserted into the shed 7 by means of a projectile 5. This is formed by warp threads 8 in the high position and by warp threads 9 in the low position.
  • the guide tooth 4 has a free upper leg 11 and a lower leg 12.
  • the legs 11, 12 form a guide channel 13 for the projectile 5 and the weft thread 6.
  • the upper free leg 11 in FIG. 1 has a straight outer edge 14, the function of which is described in detail below.
  • the drawer 2 is pivoted together with the parts 3, 4 from the position III, III 'according to arrow 1 into the position I, I', in which the weft thread 6 is struck at the stop 17 of the resulting fabric 18.
  • the parts 2, 3, 4 are again pivoted clockwise in FIG. 1. They pass through the position II, II ', in which the straight outer edge 14 of the guide tooth 4 is parallel to the warp threads 9 located in the low position.
  • the warp threads 8, 9 consist of an air-swirled yarn 24 according to FIG. 3, which contains air swirl points 21.
  • the individual, parallel fibrils 22 are held together by these.
  • the length L of the outer edge 14 of the guide tooth 4 is at least as long as the distance A between two swirling points 21, so that the edge 14 definitely hits a swirling point 21 when the guide tooth 4 sticks into the shed 7. This makes it impossible for the air-entangled warp thread 9 to be torn apart or spliced by a guide tooth 4.
  • the guide tooth described can also be used to form a guide channel of a weaving machine, in which the weft is inserted by means of an air or water jet.
