Definitions
- the invention relates to a device for inserting weft threads in weaving machines according to the preamble of the main claim.
- an entry device for weft threads is created in this older device, in which only a single clamping device is required for holding and transferring the weft thread for protection, but this single clamping device can be supplied with a multitude of different weft threads.
- a device is known in which weft threads coming from the supply spools 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 a transfer position to lead.
- the object of this known device is to create a weaving machine in which the weft thread when the Gripper protection is subject to the lowest possible voltage.
- a clamping device, as described in the older DE-PS 33 03 393, is not disclosed in this reference.
- the invention is based on the object of avoiding the pivoting clamping device still required in the device according to DE-PS 33 03 393, 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 tongs of the rapier marksman and automatically cut off on the cutting edge built into the preseeding device when the gripper marksman moves, 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 a schematic view of the B-rich e yarn transfer on a weaving machine, wherein the presenter is in the raised position, the weft thread holding device in the lowered position and the gripper shuttle is on the way back.
- weft holding devices consist, for example, of hydraulically or pneumatically actuated 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 serves 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 push L 17 is displaceable, which is equipped at its end with a cross push L 18 and is able to remove the weft from the U-shaped guide body through its open side push out.
- the preliminary layer 5 is guided downward and the weft thread 3 thereby 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, that is to say when the shooter moves in for the weft thread, the shooter first grips the part of the weft thread 3 protruding into the path of the gripping pliers 14 with the gripper 14 (right of the eyelet shown in the drawing) . Then the looper shooter 12 then guides the weft thread 3 in front of the cutting edge 8, so that the weft thread 3 is now cut off by the cutting edge 8. The free end of the weft thread 8 that is thus executed for the fabric 9 is held in the catching device 11, on the other hand the end of the weft thread 3 gripped by the gripping pliers 14 through the fabric pulled through. It should be noted here that the gripping pliers 14 are guided through the free space formed by the "U" when the shooter is flying, that is to say above the lower leg of the counter 5.
- the transverse butt L 18 of the butt 17 now presses the weft 3 drawn by the shooter out of the U-shaped guide body 6 (in the drawing to the rear through the free part) by corresponding actuation of the weft guide, so that now the VorLeger 5 again in the HochsteLLung - as shown in the drawing - can be performed.
- 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 lay-up 5.
- both the swiveling movement of the so-called pre-counter is avoided, as is the additionally required movement of the scissors or cutting device, and the cycle control of this cutting device required for this is avoided, so that the new device is easier, but works immediately.
