Definitions

  • the invention relates to a rapier weaving machine for heavy fabrics, the rapiers being arranged on rapier rods which are mounted outside the loom and rigidly guided and a first rapier introduces the weft thread into the opened loom compartment, while a second rapier takes over the weft thread in the center and carries it through the compartment and the grippers run freely on a shop sole arranged on the sheet bar.
  • Heavy fabrics are, for example, conveyor belt fabrics for belt conveyors in the top and bottom mining.
  • the invention is therefore based on the object in rapier weaving machines of the type mentioned in the preamble of the main claim, the free and straight running of the rapier through the shed also when processing high-mass lower warp threads To ensure manufacture of abnormally thick and multi-ply fabrics.
  • the invention is characterized by the technical teaching according to claim 1.
  • An essential feature of the present invention is that the thread mass in the sub-compartment, which was previously very high, is now reduced according to the invention, namely in receiving spaces which are formed between webs of the shop sole, so that the warp thread mass, which is built up per se, due to its lowering below the level the sole of the shop no longer interferes with the straight running of the grippers; i.e., the end of the gripper no longer strikes the warp thread mass of the lower compartment because this is lowered according to the invention.
  • the grippers can now be guided straight to the center of the shed.
  • the sole of the shop is designed so that it consists of individual, spaced apart and parallel webs. These webs form receiving spaces in which the entirety of the lower compartment warp threads is embedded.
  • the bars are interchangeable, but firmly attached to the sole of the shop. Their shape is adapted to the given geometric conditions of the weaving machine.
  • the free space between the webs is designed so that the maximum of the warp threads of the lower shed can be accommodated in the heaviest heavy fabrics and it is dimensioned so that the currently known conveyor belt fabrics can be manufactured using this invention.
  • FIG. 1 there is a gripper 1 which is designed in a manner known per se.
  • the thread needle 2 is currently presenting the weft 3 of the open hook 4, the gripper 1 is ready to insert the weft 3 into the open shed 6 on an outer guide piece 5.
  • the shed 6 here consists of the upper compartment 7 and the lower compartment 8.
  • FIG. 2a shows the unfavorable weaving condition with relatively few upper shed warp threads and one lower shed 8 containing a large amount of warp threads.
  • the tissue 10 is struck.
  • the weaving machine has a sheet bar 11 with a reed 12 attached to it.
  • a profile 13 is now arranged on the front of the sheet bar 11, on which the webs 14 are arranged parallel to one another in warp thread.
  • the webs 14 each form receiving spaces 15 of the same size between them, in which, according to the invention, the entirety of the lower warp threads is accommodated.
  • the number of webs on the profile 14 can be varied within free limits.
  • the number of webs is dimensioned such that a proper rapier run on the running surface 16 is ensured over the entire weaving width.
  • the distance between the individual adjacent webs 14 is not uniform but varies.
  • the distance between the webs 14 is reduced in order to increase the looper head there during the weft transfer process To provide support.
  • FIG. 2b shows this even more clearly, it being clarified that the receiving space 15 is dimensioned such that even with unfavorable fabrics (high warp thread density in the lower compartment 8 and low warp thread density in the upper compartment 7) a straight running of the hook 1 is ensured.
  • the gripper (s) always slide on the running surfaces 16 of the webs 14.
