Definitions

  • the invention relates to a device for inserting weft threads in weaving machines according to the preamble of the main claim.
  • a device for inserting weft threads in weaving machines belongs to the prior art and is described in the unpublished DE-U-8 302 758.
  • a device is known in which weft threads coming from the supply bobbins are guided in weft holding devices arranged in the area of the selvedge, which can be individually controlled from a rest position to a transfer position and thereby the weft thread to be integrated into one Lead transfer position.
  • the object of this known device is to create a weaving machine in which the weft thread is subject to the lowest possible tension when the rapier guards are driven in.
  • a clamping device as described in DE-U-8 302 758 is not disclosed in this reference.
  • the invention is based on the object of avoiding the pivotable clamping device still required in the generic device in order to thereby achieve a higher speed, while at the same time avoiding the cutting devices still required in the known devices.
  • the weft thread is thus guided into the area of the gripper pliers of the rapier protection and automatically cut off on the cutting edge built into the robe when the gripper protection is moved, this free thread end then being held by the catching device arranged in the area of the selvedge, which other thread end is pulled through the shed by the rapier.
  • the drawing shows the area of the thread transfer on a weaving machine, with the feeder standing in the raised position, the weft holding device in the lowered position and the looper shooter on the way back.
  • weft holding devices consist, for example, of hydraulically or pneumatically operated cylinders with piston rods 2 which can be guided therein and which have an eyelet 4 at their lower end which serves to guide the weft thread 3.
  • the weft feeder can be seen, which essentially consists of a laterally open U-shaped guide body 6, a cutting edge 7 being arranged in the lower region of the U leg, which is ground in the direction of the weft holding device 1.
  • a small guide slot 8 is provided in front of the cutting edge 7 in the leg of the U-shaped guide body, which is used to receive and guide the weft thread.
  • the fabric can be seen at 9, the open compartment at 10 and a thread catcher at 11, in which the cut weft threads are held in order to prevent the fabric from dissolving in this area.
  • the gripper shooter is shown, who is equipped in a manner known per se with a gripper 14 and runs in a guideway 15.
  • a weft guide 16 also consists of a hydraulically or pneumatically operated cylinder, in which a plunger 17 is displaceable, which is equipped at its end with a cross plunger 18 and is able to remove the weft thread from the U-shaped guide body through its open side push out.
  • the feeder 5 is then guided downward and the weft thread 3 enters the slot 8 and in front of the cutting edge 7 of the guide body 6.
  • the shooter When the shooter moves counter to the arrow F, i.e. So when the shooter moves in for the weft thread, the shooter first grips with the gripping tongs 14 the part of the weft thread 3 protruding into the path of the gripping tongs 14 (to the right of the eye shown in the drawing). Then the gripper shooter 12 then leads the weft thread 3 in front of the cutting edge 7, so that the weft thread 3 is now cut off by the cutting edge 7. The free end of the weft thread 3 which is thus executed for the fabric is held in the catching device 11, and on the other hand the end of the weft thread 3 gripped by the gripping pliers 14 is pulled through the fabric. It should be noted here that the gripping tongs 14 are guided through the free space formed by the “U”, ie above the lower leg of the serving mat 5, during the shooter's flight.
  • the thread deflector 19 prevents the threads held by the weft thread holding devices 1, but already integrated in the fabric, from reaching the area of movement of the guide body 6 or of the feeder 5.
