Definitions

  • the invention relates to a device for inserting weft threads according to the preamble of claim 1 and one Row shed loom with one device.
  • EP-A-0 433 216 there is a device for distributing the weft threads from a thread feeder to several weft channels
  • Weaving rotors of a series shed weaving machine which have a fixed Part and a part rotating with the weaving rotor, which in one rotationally symmetrical surface a common separating and sealing surface own and via which the weft threads are transferred.
  • the stationary part channels are formed in a known arrangement and Nozzles are provided for each channel to remove the weft threads from one of the Pull the weft supplying device and into the respective channel introduce.
  • Takeover channels are in in the part rotating with the weaving rotor formed a known arrangement and provided shooting tubes, around the weft threads fed from the nozzles into the ones on the weaving rotor to shoot trained firing channels.
  • Thread parts e.g. Fibrils in the gap between the fixed and the with can penetrate the rotating part of the weaving rotor. From this follows one Significant restriction of what is to be woven on the weaving machine Types of yarn.
  • the invention is based on the object of a device of this type improve.
  • weft threads are characterized by the features of claim 13 featured.
  • the loom has the advantage of being discontinuous Feeding the weft is possible Weft yarn free and according to a predetermined program for the Select weft entry.
  • FIG. 1 shows a weaving rotor 1 and a device 2 according to the invention for inserting weft threads 3 for a row shed weaving machine.
  • the device 2 comprises a stationary unit 4 for feeding the weft threads, a unit 5 for feeding the weft threads, which are synchronized with the weaving rotor 1 about the axis of rotation 6 in the direction of arrow A. rotates and a rotary slide valve 7 for supplying the air.
  • Unit 4 for Feeding the weft threads has a holder 8 for an arrangement 11 of Channels.
  • the unit 5 for feeding the weft threads has twelve Injector nozzles 12, which are arranged on a cylindrical support part 13.
  • the support member includes a first annular portion 14 for the Nozzle body and a second annular portion 15 for the Nozzle orifices. It should be noted that the nozzles are in one common section can be arranged and that the number of Nozzles may vary.
  • the device contains the stationary arranged unit 4 for feeding the weft threads and a unit 5 for feeding the weft threads, which are synchronous with the weaving rotor 1 turns.
  • the unit 4 for feeding the weft threads 3 contains a holder 21 and an assembly 22 mounted on the holder.
  • Unit 5 for Feeding the weft threads 3 comprises a cylindrical support part 23 and twelve injector nozzles 12, their entry and exit on the same pitch circle 24 lie.
  • the arrangement 22 comprises four units 25, the channels Form 26 and are arranged in a fan shape.
  • a component 27 consists of a first section 28 with the units 25 and a second section 29 which is connected to the units and which has an opening 30.

  • Each channel 26 has one in the direction of the axis of rotation 6 continuously tapering cross-section, so that a gap 32 for Pulling out the weft thread is formed.
  • the injector nozzles 12 are at equal intervals on a pitch circle 41 arranged horizontally such that the inlet of the injector nozzle and the Opening 30 of section 29 when taking over a weft thread 3 are aligned.
  • the inlet is advantageously the Injector nozzle expanded in a funnel shape to take over the weft thread ensure.
  • FIG. 4 shows the component 27 according to FIG. 3 in a stretched representation.
  • the stress on the weft thread while pulling it out of the To reduce channel 26 and the entry in the shed it can by It may be advantageous to vary the depth of the channel 26 as shown shape.
  • FIGS. 6 and 7. show another embodiment of the arrangement with four units 42, each two Form channels 43 and are arranged in a fan shape.
  • the arrangement is as Component 44 is formed and consists of a first section 45 with the Units 42 and a second section 46 which is associated with the units is connected and has an opening 47.
  • Each channel 43 is a nozzle 48 assigned to feed a weft.
  • the two channels 43 each Unit are separated by an intermediate wall 49 and form one common gap 50 to pull out a weft.
  • an auxiliary nozzle 51 is provided, which in the second section 46 of the component 44 is arranged so that the mouth of the auxiliary nozzle on the opening 47th is aligned.
  • FIG. 8 shows a unit 61 with four channels 43. It is on it note that the number of channels 43 may vary.
  • FIG. 9 shows eight units 62, each of which forms a channel 63, wherein each channel from a transport channel 64 and a pull-out channel 65 consists.
  • each channel from a transport channel 66 and a pull-out channel 67 shows cross-sectional shapes of designs of units, wherein each channel from a transport channel 66 and a pull-out channel 67 consists.
  • FIG. 11 shows a device 71 for the continuous feeding of Weft threads 3 with a thread conveying device 72 for each nozzle 31.
  • Figure 12 shows a device 81 for discontinuous, i.e. selective Supplying weft threads 3 with a thread store 82 for each nozzle 31, wherein the thread store is provided with a thread stop member 83.
  • the device contains a stationary unit 4, the one Arrangement 22 having a plurality of channels 26 and a plurality of Has nozzles 31 for supplying weft threads 3 and one with the Webrotor 1 rotating unit 5 with a plurality of injector nozzles 12, the for this purpose, the weft threads fed to the channels are successively subtract and feed into the shed.
  • This device ensures the insertion of weft threads different types and designs.
