Definitions

  • the invention relates to a method and a weaving machine for handling a weft thread according to the preamble of claim 1.
  • auxiliary warp threads In the case of weaving machines, it is known to attach the actual fabric warp threads to the To provide so-called auxiliary warp threads to fabric edges.
  • the auxiliary warp threads are in led an auxiliary council. Between the fabric warp threads and the auxiliary warp threads is a more or less large distance is provided, so that e.g. an insertion device and a cutting device can be arranged.
  • the The task of the auxiliary warp threads also referred to in their entirety as a catch strip, is pick up the weft and ensure its tension so that the Weft thread can be cut off properly by the cutting device. This will u. a. also achieved in connection with a so-called stretching nozzle that the The weft thread is caught when it exits the weft channel and is kept under tension.
  • the catch rail is usually a few centimeters wide and applies after doing its job as a waste product. So one does not collect small amount of fabric residues, so that an increased during the weaving process Material consumption, d. H. Warp and weft consumption and thus higher costs arise than are absolutely necessary.
  • the object of the invention is to provide a method and an apparatus for handling the To propose weft in looms of the type mentioned at which can be dispensed with the use of the catch strips.
  • An essential feature of the invention is that the use of catch strips entirely is avoided and the loom has a suction device which is arranged in the area of the insertion device in front of the first shot guard.
  • the suction device is located in the free space between Insertion head / cutting device and the first weft monitor, which Gap in the state of the art through the auxiliary warp threads (catch strips) was taken.
  • the catch strips are therefore eliminated.
  • the suction device has the task of the weft thread gripped by the stretching nozzle to take over after successful thread entry and keep it taut so that the Thread can be cut by the cutter. After cutting the cut thread remnant is removed by the suction device.
  • auxiliary warp threads (catch strips) can be dispensed with and as a result material and cost savings are achieved.
  • suction device in the by omitting the Catching strips become free space is arranged so that it is not necessary To dispense with other important components due to lack of space.
  • FIG. 1 shows the reed 1, in which a large number of warp threads 15 run.
  • To the Reed 1 closes the fixed one in the rear position of reed 1
  • Filler 2 on which has the task of the weft channel of the reed 1 extend and ensure a successful shot entry.
  • At the level of Filler piece 2 is an insertion device 3 in the stop position of the reed 1 arranged.
  • the stretching nozzle 6 the has a channel 14, a second at the end of this channel Weft monitor 7 is arranged.
  • a suction device 8 with a suction opening 8a is arranged according to the invention, which works with a vacuum pump 9.
  • a Collection container 10 For suctioned thread remnants is a Collection container 10 provided.
  • FIG. 1 An insertion nozzle 12 which carries the weft 16 into the Weft channel of the reed 1 and thus brings in the shed 19.
  • Auxiliary nozzles 13 guide the weft thread 16 in the weft channel 1a.
  • the Weft channel 1a continued so that the front portion of the thread in the area of the filler 2 to the first weft guard 4, the Drawing nozzle 6 comes into action, which grasps the front section of the thread and the Keeps the thread taut.
  • the reed 1 now moves with the necessary ones Devices forward from the rear position to the weft 16 to the Attach tissue.
  • the front section of the weft thread 16 is thus held in the drawing nozzle 6 and curious; excited.
  • the suction device 8 according to the invention is now activated, wherein at the same time the stretching nozzle 6 is deactivated so that the weft thread of the Extending nozzle 6 is passed to the suction device 8 and through this under Tension is held.
  • At least part of the front can be cut by a cutting device 11 Weft section are cut off.
  • the cut off part of the Thread section remains in the suction device and is by this in the Removed container 10.
  • the thread residue protruding from the fabric 21 can be made by a known thread Insertion device 3 on the fabric edge in a after the weft stop formed shed are inserted or returned.
