Definitions

  • the invention relates to a method for processing non-swirled or partially swirled Weft yarns, especially synthetic filament weft yarns while running Further processing of the weft yarns on an air jet weaving machine and weaving machine Execution of the procedure.
  • weft insertion medium Air will unravel the yarn if the entry medium does not adhere to the yarn swirled yarn section detected.
  • Such a section of yarn can prove to be a relatively large one Show the distance between two interlacing points in the weft.
  • the object of the invention is therefore, the aforementioned weft yarns before Weft entry of a swirl or at least one post-swirl undergo in order to make them processable on air jet weaving machines.
  • the object is achieved in that the weft after removal from a supply spool and before buffering on a thread storage in Depending on the speed at which the yarn is drawn off, the thread supply is swirled or at least post-swirling, namely by the weft yarn in one known pneumatically operating swirling device with a pneumatic, pressure-controlled fluid is applied.
  • the intermingling device is connected to a pneumatic pressure control unit of the weaving machine, which in turn is signal-transmitting to the programmable weaving machine control, as is also the case for the thread store.
  • the intermingling takes place continuously in terms of control technology, depending on the take-off speed of the weft yarn.
  • control technology namely when the intermingling process is either started or ended when the switching on and off is controlled.
  • a filament weft yarn 2 which is not or only partly interwoven is wound up.
  • the weft yarn 2 is fed to an electrically controllable pre-winding device 3 while passing a swirling device 4 known per se.
  • the weft yarn 2 passes from the prewinder 3 to the pneumatic weft insertion member 11 of an air jet weaving machine, not shown.
  • the interlacing device 4 is thus placed between the thread supply 1 and the prewinder 3.
  • the pre-winding device 3 is connected in a signal-transmitting manner to the programmable logic controller 6 via the control line 5.
  • the pressure control unit 7 consisting of a proportional pressure control valve 7a and a pressure transducer 7b, is connected to the controller 6 in a signal-transmitting manner via the control line 8.
  • the control unit 7 is integrated in a pressure line 9, which leads from the pressure source 10 to the swirling device 4.
  • Viscose filament yarn e.g. of fineness 330 dtex are without swirling on the Thread supply 1 spooled. These yarns have a so-called protective twist of 70 - 90 T / m. In most cases, however, there is no thread closure with the protective twist reached, a blown yarn during the weft insertion by the entry organ 11 prevented. In this respect there is a swirling of the weft yarn before the weft insertion required.
  • the pre-winding device 3 is controlled via the control line 5 by the controller 6 and the Drum of the pre-winding device 3 set in rotation.
  • the yarn 2 with one in the Control 6 deducted rotation speed deducted from the yarn supply 1.
  • the control unit 7 is switched on Control line 8 driven.
  • the control unit 7 thereby clears the way for a pneumatic fluid under the pressure p1 of the pressure source 10 via the pressure line 9 to the swirling device 4. Since the pressure-regulating unit 7 is integrated in the pressure line 9, the required pressure p2 of the fluid causing the interlacing of the weft yarn in the interlacing device 4 can be regulated as a function of the take-off speed of the prewinder. If, for example, a high take-off speed of the weft yarn 1 is required, the pressure p2 is automatically adjusted accordingly.
  • the pressure p2 on the interlacing device 4 concerned also goes to zero when the pausing device 3 is at a standstill, ie when the take-off speed is zero. This prevents the weft yarn from being over-swirled.
