Definitions

  • a rapier gripper for a rapier weaving machine e.g. Ribbon or bar rapier weaving machine
  • the clamping tongue has a tapered, free end of the same rigidity as the rest of the tongue part.
  • the entire clamping tongue is made of flat steel.
  • the clamping tongue cannot spring transversely to its longitudinal direction compared to the clamping jaw. If two or more threads are to be inserted into the weaving shed of the loom at the same time with this arrangement, only one of the threads can be securely held in the clamping slot between the tongue and the clamping jaws, the other threads can easily be lost from the clamping slot during the weft insertion (thread loser ).
  • the clamping effect is only optimal with one thread, with the others it is more or less weak and not sufficient for a secure hold.
  • the invention is based, one in particular in this regard to create improved hand grabs.
  • the invention consists in the fact that the free end of the clamping tongue has an extension part that also lies against the clamping jaws and resiliently rests transversely to the longitudinal direction of the clamping tongue.
  • the extension part consists of at least one additional tongue carried by the clamping tongue, which protrudes beyond the free end of the carrier tongue and the additional tongue is adjustable and fixable transversely to its longitudinal direction on the carrier tongue.
  • the clamping slot existing between the additional tongue and the clamping jaws can be adapted to the thickness of the weft threads to be inserted, as a result of which an optimal clamping effect for the weft threads, in particular for the subsequent weft thread located in the clamping slot, can be achieved.
  • the bringer gripper designated as a whole by 21, contains two side walls 22, 23, which are continued in two upper lugs 24, 25.
  • the lugs 24, 25 overlap one another and are connected to one another by a connecting part 26.
  • the two side walls 22, 23 are connected to one another by a web 27, the left part of which in FIG. 2 is designed as clamping jaws 2 for two weft threads 4, 9 introduced into slot 30 ′.
  • the web 27 contains a trapezoidal recess 33 with an inclined wall 34 and a vertical wall 35.
  • the tongue 5 carries an additional clamping tongue 7 fastened by means of a screw 6, the tip 41 of which in FIG protruded on the left over the end 42 of the carrier clamping tongue 5)
  • the additional tongue 7 is formed much thinner than the carrier tongue 5.
  • the carrier tongue 5 is 2 mm thick
  • the additional tongue 7 is 0.4 mm thick.
  • Carrier tongue 5 and additional tongue 7 are pressed upwards into the trapezoidal recess 33 of the web 27 by a corresponding pretensioning of the tongue 5 in FIG. 2 (arrow A).
  • the additional tongue 7 contains a slot 8. Because of this slot and because of its small thickness relative to the thickness of the carrier tongue 5, the additional tongue 7 can spring horizontally in Fig. 2 and vertically in Fig. 1 (arrow B), while the carrier tongue 5 due to its strong Training in this direction is not flexible.
  • the additional tongue 7 can also be adjusted by adjusting the screw 6 relative to the carrier tongue 5 and in a desired position in which the inlet slot formed by it and the clamping jaws 2 at 35 for the weft threads 4,9 of the type and in particular the thickness these two threads can be adjusted.
  • the carrier tongue 5 carries, in addition to the upper additional tongue 7 in FIG. 5, a lower additional clamping tongue 10 which is designed corresponding to the tongue 7. The security of the clamping in the slot 30 can thus be increased.
  • the clamping jaw 2 contains an additional shoulder 48, in which the lower additional clamping tongue 10 lies.
  • the threads 4.9 are thereby held at 30.35 and at 48 with a right-angled kink, which also results in increased security during the double weft entry.
  • the additional tongue 7 is mounted on the carrier clamping tongue 5 at a pivot point 36 '. It is of the same thickness as the tongue 5, so it does not spring in accordance with arrow B.
  • the suspension in the direction of arrow B is achieved in this type by two compression springs 51, which strive to pivot the additional tongue 7 in Fig. 7 by 36 '. This creates a non-positive +) clockwise
  • the additional clamping tongues 7, 10 form a front extension of the carrier tongue 5.
  • a design according to the invention also arises when e.g. 3, although there is only a single clamping tongue 3, the front part comprising the tip 45 is, however, substantially thinner than the rest of the part or - with the same thickness - for example made of a flexible plastic, e.g. Polyamide (NYLON) is made.
  • a flexible plastic e.g. Polyamide (NYLON)
  • three or more threads can optionally also be introduced into the inlet slot 30.
  • the tongues 5,7, 10 can e.g. are made of steel. After the weft entry, the gripper 21 is moved out of the shed.
  • an attachment 60 attached to eungesan passes under a fixed cam 70, as a result of which the tongues 5, 7 are moved downward against their spring action in FIG. 2 according to arrow D.
  • Slit 30 can now be cleaned of fiber fly by a blowing or suction device.
