Definitions

  • the invention relates to an entry nozzle arrangement of an air jet weaving machine, with at least two nozzles for the weft insertion, which are optionally activated according to an entry program and are arranged outside of the shed on a weaving machine part.
  • the two-shot nozzle arrangement is pivotally arranged on the drawer of the weaving machine.
  • the nozzle with its air outlet pipe is pivoted into the weft line, the weft thread of which is required for the following weft insertion.
  • the invention has for its object to provide a particularly improved arrangement in this insight.
  • the invention consists in that the two nozzles are firmly attached to the weaving machine part carrying them and that one of the nozzles - at least in the entry position of the parts - essentially parallel to the weft line and the other nozzle at a slight angle of inclination, preferably 1-5 ° to this stands.
  • the invention is based on the knowledge that - as the tests have shown - it is possible to permanently install one nozzle, preferably parallel to the firing line, and the other at a certain, small angle of, for example, 3 °, so that the two nozzles during operation do not have to be moved relative to the line of fire or the reed or other guiding means for the air jet (e.g. guiding teeth).
  • the small angle of inclination of the second nozzle relative to the first nozzle is particularly possible when the second nozzle blows against the reed at the small angle and not away from it. It can e.g. B. a so-called tunnel reed (profiled reed) can be used, the tunnel of which is formed from the profiling of the slats.
  • a reed 3 consisting of profiled slats 2 is attached.
  • the slats 2 together form an entry tunnel 4, in which the weft insertion line 5 lies.
  • a carrier 6 is adjustable and fixably connected to the drawer by a screw connection 8 provided with slots 7, as a result of which the distance C (FIG. 2) can be changed.
  • a block 12 is fastened by means of a screw 11, on which two weft insertion nozzles, designated as a whole by 15, 16, are firmly attached.
  • a weft thread 21 shown in FIG. 1 in dash-dotted lines. B. different color, ready for a weft entry. The weft threads are drawn off from weft thread stores 61, 62.
  • the free, circular cross-section end 17a is placed parallel to the firing line 5, the free, likewise circular cross-section end 19a of the mixing tube 19 is at an angle A of approximately 3 ° to the firing line 5.
  • the two ends 17a, 19a of the mixing tubes 17, 19 are held in a guide 23.
  • the two outflow openings 51, 52 are generally arranged as close as possible to one another, preferably touching one another.
  • the angle A can be set by means of a screw connection 45, which has a flange 48 attached to the nozzle 16 with a slot 47 extending perpendicular to the plane of the drawing in FIG. 1.
  • drawer 1 and reed 3 as well as the entire nozzle arrangement designated 24 are moved back and forth according to arrow 25 and z. B. alternately according to the weft insertion program, a thread 18 or 21 entered in the shed 41 formed by the warp threads 42, 43.
  • block 12 and guide 23 are firmly connected to the frame 48 of the weaving machine.
  • the Nozzle arrangement 24a is not moved back and forth with reed 3 during weaving operation.
  • the nozzles in turn form an angle A of approximately 3 ° to one another.
  • the mixing tube of the nozzle 16 is directed with the free end 19a (angle A) such that it blows against the base 49 of the tunnel 4 at an inclination of approximately 3 °.
  • the angle A lies in the horizontal plane, designated by E in FIG. 1, shown in dot-dash lines and running through the fabric stop 50 and the tunnel base 49, i.e. 2, 4 parallel to the plane of the drawing.
  • a three-shot mechanism which contains a third nozzle with a mixing tube 32. This is inclined at a somewhat larger angle B of approximately 4 ° against the firing line 5. All three mixing tubes 17, 19, 32 of the three nozzles are arranged in the horizontal plane running through the fabric stop 50 and the tunnel base 49, i.e. 7 parallel to the plane of the drawing.
  • the end 17a of the mixing tube 17 is at least in the entry position of the parts or in any position, i.e. also during the movement of the reed 3 towards the fabric stop 50, in each case parallel to the line of fire 5, the end 19a of the mixing tube 19 is at an angle A to the end 17a of the mixing tube 17.
  • a reed with unprofiled, straight lamellae is used instead of a tunnel reed, and the entry tunnel is formed by guide teeth positioned in front of the reed, into which the entry nozzles 15, 16 or their ends 17a, 19a blow.
  • the firing line 5 then lies within the guide teeth mentioned.
