Definitions

  • Such a projectile weaving machine is e.g. in DE-PS 27 12 431 (T.470).
  • projectile weaving machines of this type unlike other weaving machines in which the weft insertion is carried out by means of rapier bars, rapier belts, compressed air or water nozzles, it is not absolutely necessary to cut off the weft thread ends on the catch side, since the position of the weft thread end is always theoretically defined.
  • FIG. 2 corresponds to that described, with the difference that the projectile opener 42 on the catch side is omitted, that the cut thread end 44 is left in the projectile 10 during the return transport, and that the suction and blowing device 46 is arranged in the firing mechanism 12.
  • the weft-side projectile opener 43 is therefore sufficient to remove the thread ends.
  • the blowing nozzle 72 has a branch 74 which opens into the suction pipe 64. In this way, an increase in the suction effect can be achieved.
