Definitions

  • the invention relates to a device for pulling off separated fabric parts at the edge of a fabric produced on a weaving machine, e.g. of auxiliary edges or protruding weft ends.
  • an auxiliary edge is formed on the catch side of the fabric and is cut off with a cutting device, for example, the auxiliary edge is passed through two intermeshing gear wheels, whereby it e.g. gets into a waste container.
  • the auxiliary edge is sucked off by a suction nozzle on the edge of the fabric, which is connected to a fan.
  • the auxiliary edge is passed through a hose into a waste container.
  • auxiliary edges or weft ends are not suitable for fabrics which contain sensitive yarn in the weft and / or warp, for example threads made of glass fibers or particularly smooth, thin fibers, such as chemical fibers or the like.
  • tissue parts to be removed are destroyed, for example, in the known gear drives that pull them off.
  • the glass fibers break, loosen from the bandage of the auxiliary edge and fall down. They cannot then be collected in the waste bin.
  • sensitive yarns are only taken along with the effort of a strong air flow with a correspondingly high air consumption. There is a risk that the auxiliary edges will be blown away.
  • the invention has for its object to provide a particularly improved device in this regard.
  • the invention resides in a conically converging injector nozzle, which encloses the air radiation and surrounds the tissue part to be removed, in the region of the edge of the draining tissue.
  • auxiliary edges made of finer material without greater, own yarn strength of the auxiliary edge, e.g. Glass fiber / containing auxiliary edges to be peeled off.
  • the air consumption is relatively low, although particularly high air speeds can be generated in the injector nozzle. This can e.g. 140 to 150 m / sec. If such a flow rate of the suction air is to be achieved comparatively by a suction fan, an extremely high output of the suction fan in question is required, which leads to high operating costs.
  • the weaving machine 1 contains side cheeks 2, 3, a drive motor 4, a main shaft 5, a weft supply spool 8 remaining outside the shed, a weft mechanism 9, a catching mechanism 10, shafts 11, a reed 12, a fabric tree 14 and a turning device 16 on the catching side the machine 1.
  • the latter has an auxiliary edge 18 produced by the turning device 16, which after scraper stop 50 (FIG. 3) by means of scissors •)
  • the fabric 13 and the auxiliary edge 18 on the catch side are pulled off a goods take-off roller 19 in accordance with the arrows 21, 22. Subsequently, at the point 20, the auxiliary edge 18 is pulled off an injector nozzle designated as a whole by 25 and passed through a hose 26 into a waste container 27 according to arrow 28.
  • the fabric 13, after it has been freed from the auxiliary edge 18, is cut over deflection rollers 23, 24 * ) 60. according to arrow 29 on the rotating goods tree M according to arrow 31.
  • the injector nozzle 25 has a tube 33 which forms a withdrawal channel. According to arrow 35, compressed air is conducted via an air supply channel 36 into an annular arm 37 which is formed in an annular insert 38. From the annular space 37, the air passes into the duct 33 through a plurality of air supply elementary ducts 39 arranged on a circle according to arrows 41. The axes 42 of the ducts 39 are at an angle A of approximately 20 ° with respect to the axis 43 of the duct 33 directed to an intersection 45.
  • An axially displaceable taper insert 48 is inserted in the flow direction after the channels 39 with the interposition of seals 47, by means of which the air flow receives a Venturi acceleration.
  • the insert 48 is positioned so that its initial cone 49 encloses the point 45.
  • the auxiliary edge 18 introduced from the left in FIG. 4 consists of a central strand 52 containing a plurality of warp threads 51, in which cut weft ends 53 are woven and held by the leno weave 16 created by the leno device 16.
  • the weft ends 53 consist, for example - like the entire weft threads 6 - of glass fiber material, as a result of which the auxiliary edge 18 has only a very weak, inherent internal strength.
  • the ends 53 made of glass fiber material can break particularly easily and fall out of the central strand 52.
  • the auxiliary edge 18 is introduced in FIG. 4 through the air supplied through the elementary channels 39 into the injector nozzle 25 (arrow 28), the weft ends 53 due to the curvature 56 of the insert 38 come into the curved position 53a. In this they slide with their ends over the curved inner circumference of the insert 38.
  • the ends of the weft threads are transferred into the reverse curvature position 53b by the air flowing in from the elementary channels 39 and are transported or pushed further to the right in FIG. 4 by the flowing air.
  • the auxiliary edge 18 passes through the venturi insert 48 and is passed on according to arrow 61, specifically through the pipe 26 into the waste container 27.
  • air guide element channels 39a arranged skewed in the ring insert 38 are used, which generate a rotating flow according to the arrows 62 in the nozzle 25. It can thereby be achieved that the auxiliary edge 18 is twisted together by producing a so-called false wire and is thereby strengthened.
  • auxiliary edge 18 By carrying the auxiliary edge 18 by means of the individual air jets coming from the elementary channels 39, the auxiliary edges 18 with the particularly sensitive weft ends 53 are spared and are nevertheless subjected to a relatively strong entrainment effect. These thread ends 53 do not tend to break and cannot fall out of the strand 52, so that the auxiliary edge 18 can be diverted undamaged.
  • the pull-off injector nozzle 25 In another application of the pull-off injector nozzle 25, projecting weft ends that are to be cut are pulled off the shed 17. The injector nozzle 25 is then arranged directly at the point where the weft ends are cut off, preferably in the ver Extension of the weft line or the weft thread 6 (Fig. 3). The injector nozzle 25b can be positioned perpendicular to the weft thread 6, as indicated by the broken line in FIG. 3. The nozzle is then moved to position 25a and the weft thread to position 6a when the blade stops.
  • the air supply via the channels 36, 39 can take place continuously or in pulses according to a certain rhythm corresponding to the working cycle of the weaving machine, preferably at the time the weft threads arrive on the catching side of the weaving machine in the catch mechanism 10.
  • a device corresponding to the lathe device 16 and an injector nozzle 25 for pulling off an auxiliary edge or weft thread ends can also be provided on the side of the weft mechanism 9.
