Definitions

  • the invention relates to a device for detecting weft ends for row shed looms.
  • weft thread After the weft thread has been inserted in a row shed weaving machine and cut through on the weft side, it must be held in the weft thread ends protruding from the rotating weaving rotor on both sides until the point of impact in the fabric.
  • DE-PS 2 704 786 describes a weaving machine in which a plurality of weft insertion systems are co-rotating on a rotor. There, for each weft insertion system, co-rotating thread holding members are described, which are fed to the weft side of a single rotating cutting disk fixed relative to the rotor.
  • the closing and opening of this large number of thread holding members on a rotating weaving rotor requires complex, precise mechanics, the setting of which is critical, difficult and time-consuming.
  • the invention has for its object to provide a device for detecting a weft end piece on a row specialist machine with a rotor, is fixedly arranged with respect to the rotor and detects the weft end pieces of several weft insertion systems.
  • This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous embodiments.
  • a weaving rotor 1 is provided with a number of weft thread combs 2 and weft insertion combs 3 that alternate on the circumference.
  • the weaving rotor is rotatable about an axis 4 and driven in the direction of arrow 5.
  • the weaving rotor 1 On its weft side 6, the weaving rotor 1 has a weft driver ring 7, which has a weft guide opening 8 opposite each insertion comb 3.
  • a weft thread clamping and cutting device 9 is attached to the weft side 6 of the weaving rotor 1, and a weft thread clamping and cutting device 11 is attached to the catching side 10 of the weaving rotor.
  • the weft-side device 9 consists of a weft thread clamp 12, a weft thread scissors 13 and a weft thread suction pipe 14.
  • the clamp 12 consists of a clamping lever 15, which is fastened on a control shaft 16, and a clamping groove 17 in the suction pipe 14.
  • the end scissors 13 has a scissor blade 18 , which is fastened with a pin 19 on the clamping lever 15 and cooperates with a counter blade 20, which is fastened on one side 21 of the suction tube 14.
  • a wire spring 23 is fastened to the suction pipe with a screw 22 and lies in a groove 24 in the suction pipe 14, with the exception of an upper section 23 'which lifts off the suction pipe.
  • the wire spring 23 is adjustable in height so that its support length is adjustable.
  • the suction pipe 14 opens on the one hand into a suction gap 25 and on the other hand into a suction nozzle 26.
  • the suction nozzle 26 is in turn connected to a vacuum source via a hose 27.
  • the weft thread clamping and cutting device 11 on the catch side 10 of the weaving rotor 1 is built in mirror image of the device 9 described.
  • the clamp of this device is designated 34, the clamping lever 35, the associated groove 36, the end scissors 37, the scissor blade 38, the counter blade 39, the suction tube 40, the suction gap 41 and the wire spring 42.
  • the clamping lever 35 is also attached to the control shaft 16, which is rotated forwards and backwards in the machine rhythm by a control disk driven by the main shaft of the loom.
