  • the control unit used for controlling the shut-off valves can also control various other components of the weaving machine, for example the valve 131 shown in Fig. 1 .
  • the thread clamp 105 further comprises a stop lever arm 20 that can co-operate with a stop 21.
  • the stop 21 can be mounted in an adjustable position by a positioning element 22, for example a setting screw. Further, in the embodiment shown the stop 21 comprises a stopping element 23 that can co-operate with the stop lever arm 20 and that for example is formed of a material with damping properties.
  • the operation is as follows: When the thread clamp 105 is closed with a certain force, the clamping part 170 and the clamping part of the clamping element 160 contact each other and the stop lever arm 20 beats up against the stop 21, so that the clamping force is restricted and the moveable jaw 17 does not act with full force on the plate 161 of the fixedly arranged jaw 16.
  • the stopping element 23 features damping properties and this allows an elastic deformation during the co-operation with the stop lever arm 20.
  • impact forces are damped. Therefore, it is possible to control the pneumatic drive 15 with a large force, so that the thread clamp 105 can close fast enough and there is also sufficient clamping force present just after the closing, while the damping properties of the stopping element 23 are advantageous to restrict the impact of the beating up against the stop 21.
  • the pneumatically driven thread clamp 105 is adapted to allow to be controlled for opening or closing in any position of the sley 500.
  • the thread clamp 105 is controlled for clamping an inserted weft thread upon the beat-up motion of the reed 5.
  • the inserted weft thread is caught and stretched by the weft thread stretching device 7 and transferred to the thread clamp 105 when the thread clamp 105 passes the weft thread stretching device 7.
  • the weft thread 2a caught by the thread clamp 105 is subsequently introduced into the weft thread holding device 9. Upon this transfer to the weft thread holding device 9 the thread clamp 105 is operated to release the caught weft thread 2a.
  • the guiding device 10 comprising a thread clamp 105 is also provided with an adjustable stopping element 103, which defines the depth of the opening formed by the two clamping elements 160, 170.
  • the thread clamp 105 of Fig. 10 can herewith act as the hook-shaped guiding element 100 of Fig. 4 .
  • the thread clamp 105 of Fig. 10 can also act as the hook-shaped guiding element 100 of Fig. 4 that guides the caught weft thread 2a towards the weft thread holding device 9 and can thereby, for example for relatively elastic weft threads, in addition to the weft thread stretching device 7 prevent that the weft thread is pulled back into the fabric.
  • Fig. 11 and 12 show a variant embodiment of a weft thread holding device 9 to be used in a device 1 shown in Fig. 1 or 9 .
  • the weft thread holding device 9 shown in Figs. 11 and 12 comprises a suction opening 903, which is formed by a tube.
  • the aperture of the suction opening 903 faces the reed 5.
  • the entry slit 900 is provided at a distal end of the suction opening 903 .
  • the entry slit 900 is formed by two grooves 907, 908, which are arranged into the tube that is forming the suction opening 903.
  • the two grooves 907, 908 are provided in two parallel planes.
  • the groove 908 which is arranged in use of the weft thread holding device 9 closer to the fabric edge 801 (see Fig. 1 or 9 ) is sufficiently long in order to allow introduced weft threads to be held and stretched until these are bound by the warp threads 3 without bending the introduced weft threads about a ground of the groove 908, i.e. for allowing the weft threads to extend in an essentially straight line between the weft thread holding device 9 and the fabric edge 801.
  • the groove 907 at the opposite side of the suction opening 903 is provided with two mutually opposing retaining edges 905.
  • the retaining edges 905 are slightly inclined towards the inside of the weft thread holding device 9 in order to allow an undisturbed introduction of a weft thread (not shown), while restricting a retraction or withdrawal of the introduced weft thread.
  • the retaining edges 905 are preferably provided at an entry region 904 of the entry slit 900 as shown in Figs. 11 and 12 . Therefore, the groove 908 is longer than the groove 907. In other embodiments, the groove 907 extends beyond the retaining edges 905 provided for example in the form of a number of barbs and has the same length as the groove 908.
  • An auxiliary nozzle 14 is provided in the region of the entry slit 900 of the weft thread holding device 9, which auxiliary nozzle 14 is blowing towards the inside of the weft thread holding device 9.
  • the device, the weaving machine with the device and the method according to the invention are of course not limited to the embodiments, which have been described by way of example and are illustrated in the figures.
  • the device, the weaving machine and the method can likewise be embodied within the claims in accordance with variant embodiments, shapes and dimensions. Combinations of the illustrated embodiments that fall under the claims are also possible.
