Definitions

  • the invention relates to a guide device for weft insertion elements for weaving machines, in particular rapier projectile weaving machines, with an outlet opening for guide teeth having the weft thread.
  • the known projectile guiding devices (CH-PS 465 521; CH-PS 315 854) have guide teeth with a relatively small outlet opening for the weft thread.
  • This has the disadvantage for shed geometries to achieve tissue image structures of a special kind that if the guiding device dips down out of the shed while the shed is being closed at the same time, the weft thread is hindered when leaving the guiding device.
  • This disadvantage is particularly evident in so-called "in-bag weaving" because the upper and lower warp threads cross at a lower level, i.e. below the normal web level. The weft then strikes hard along the upper inner edge of the guide tooth, which leads to undesirable streaking in the tissue.
  • the invention has for its object to provide a guide device of the type defined in the introduction, with which streaking in the tissue is avoided. This task 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 teeth 3, which are cast in a block 4.
  • the guide teeth 3 have an outlet opening 5 for the weft thread.
  • a projectile located in the guide channel 6 and the weft thread carried by it are designated by the reference numbers 7 and 8, respectively.
  • the drawer 1 with the guide device 2 is located in front of the stop of the weft thread 8 in a shed 9, formed by the warp threads 10 and 11.
  • the position of the guide device 2 when the weft thread 8 stops in the shed pocket 9 is denoted by 2 '.
  • Each guide tooth 3 has a guide support 3 'and a guide hook 3 ", which closes off the guide channel 6 at the top.
  • the guide support 3' and the guide hook 3" have a length such that the outlet opening 5 for the weft thread 8 is only insignificant from the adjacent one Side 7 'of the projectile 7 is removed, and runs essentially parallel to the bevel 7 "of the projectile.
  • FIG. 1 clearly shows that the outlet opening 5 is significantly larger than the outlet opening 12 of a known tooth, which is indicated by a dash-dotted line ben and the ends approach so close that only a small outlet opening remains.
  • the large outlet opening for the weft thread allows the weft thread to emerge unhindered when the guide device for striking the weft thread dips downward while simultaneously closing the shed.
  • the enlarged weft thread exit opening i.e.
  • FIG. 2 A guide device 15 consists of a number of guide supports 16 and guide hooks 17 which are cast in a block 18. The supports 16 and hooks 17 alternate in the longitudinal direction of the guide device and form a pair of complementary guide teeth 19, leaving an exit opening 20 for the weft thread.
  • the projectile is identified by reference number 21. The same conditions apply to the outlet opening 20 as are specified for the outlet opening 5 of FIG. 1.
