Definitions

  • the invention relates to a ribbon loom according to the preamble of claim 1.
  • a ribbon loom of the type mentioned is known from DE-PS 24 00 101.
  • the opening plane of the longitudinal slot of the insertion needle is arranged transversely to the plane of movement of the insertion needle and the hook lies within the longitudinal slot on an edge of one leg of the legs forming the longitudinal slot.
  • the object of the invention is to design a ribbon loom of the type mentioned at the outset in such a way that the disadvantages mentioned are avoided.
  • the hook Due to the fact that the hook is arranged outside the longitudinal slot of the insertion needle and is directed at least approximately in the plane of movement of the insertion needle against the thread guides, the hook does not limit the opening of the longitudinal slot, so that the latter can be made much narrower, solely on the guidance of the or consideration must be given to the weft threads.
  • a narrower longitudinal slot in turn leads to a narrower insertion needle, which means that the shed no longer has to be opened so far and therefore the smaller shafts of the corresponding shafts are sufficient. This in turn leads to smaller and faster drives, which can increase the performance of such a ribbon loom.
  • the opening plane of the longitudinal slot of the insertion needle can lie in the plane of movement of the insertion needle.
  • the weft threads are guided very tightly in the longitudinal slot, so that there are limits to the crossing of a weft thread to be inserted with a weft thread in the selection position.
  • Intermediate stages of the formation of the insertion needle are also possible, in which the opening plane of the longitudinal slot forms an angle between 0 and 90 to the plane of movement of the insertion needle.
  • the weft threads can cross more easily in the longitudinal slot.
  • the hook can be arranged on the lower or upper leg of the insertion needle, depending on whether the thread guides are moved down or up when hiking into the selection position.
  • a particularly narrow and stable design of the insertion needle results from the design according to claim 4. This makes it possible to further develop the hook-free leg of the insertion needle according to claim 5.
  • the weaving machine has a support plate 4 arranged on a machine frame 2, which serves to support and guide the woven goods 6. At the front end of the support plate there is a breast beam 8, over which the woven goods are connected is led to a goods tree, not shown.
  • the rear end of the support plate 4 serves for guiding and holding the goods on the stop edge 12, from which the warp threads 14 lead via a shedding device 16 to a warp thread delivery device, not shown.
  • the machine frame 2 contains a drive device, not shown, which drives an oscillating shaft 18 on which an arm 20 is arranged which carries a weft insertion needle 22.
  • the insertion needle 22 is used to insert one or more weft thread loops 24 into the shed 26 formed by the warp threads 14.
  • a reciprocating knitting needle is arranged, which serves to bind the inserted weft thread loops 24. Successive weft loops can be forfeited and tied with themselves and / or with an auxiliary thread.
  • a reed 32 which is arranged on a swivel arm 30, serves to attach the inserted weft thread loops to the stop edge.
  • the insertion needle 22 contains a longitudinal slot 34, the opening plane of which is transverse to the plane of movement of the insertion needle.
  • This longitudinal slot is formed by two legs, the upper leg 36 having a rectangular cross section, the main axis of which lies in the plane of movement.
  • a hook 40 is formed by a step-by-step taper 38, the tip 42 of which points towards the free end of the insertion needle 22 and is directed against rear thread guides 44a, 44b, for weft threads 46a, 46b .
  • the lower leg 48 of the insertion needle 22 delimiting the longitudinal slot 34 is weaker and is preferably formed from a wire 50.
  • a plurality of weft threads 46a, 46b can be guided in the longitudinal slot 34, in the present case only two are shown.
  • the weft threads 46a, 46b lie at the lower edge of the longitudinal slot 34, i.e. on the lower leg 48, as shown in FIG. 3 and in particular in FIG. 4 for the weft thread 46b.
  • the weft threads 46a, 46b lie outside the engagement area of the hook 40. If a thread guide 44a and / or 44b (thread guide 44a in FIG.
  • weft thread 46a and / or 46b (weft thread 46a in Figure 4) led obliquely upwards, whereby it reaches the engagement area of the hook 40.
  • the weft thread recorded in each case is inserted into the shed 26 by the insertion needle 22 in the form of a loop and is held and tied on the opposite side by means of the knitting needle 28.
  • any programmable devices can be provided for the selection of the weft thread to be inserted into the shed 26 from a plurality of the weft threads 46a, 46b guided in the longitudinal slot 34, e.g. a cam device or the like.
  • the selection can also be made by the shedding device, for example a dobby, a single strand control or a jacquard machine. The latter is shown in the present example and its strand bundle 50 can be seen, which is led through a choir board 52 provided with holes.
  • FIG. 5 shows a further exemplary embodiment of a weft insertion needle 54 which, in contrast to the weft insertion needle 22 of FIGS. 3 and 4, has a longitudinal slot 56, the opening of which lies in the plane of movement of the insertion needle 54.
  • a hook 60 is arranged, which is arranged and designed analogously to the hook 40 of the insertion needle 22.
  • the front leg 62 of the insertion needle 54 delimiting the longitudinal slot 56 is also weaker, as is also the case with the insertion needle 22.
  • the function of this insertion needle 54 with respect to the insertion of the weft threads 46a and / or 46b corresponds to the workflow already described above.
  • entry needles 22 and 54 are also possible.
  • the opening plane of the longitudinal slot can optionally be arranged at an angle which fluctuates between 0 0 and 90 0 to the plane of movement of the entry needle.
  • Straight needles with straight back and forth movements are also possible.
