Definitions

  • the invention relates to a method and an apparatus for pneumatic insertion of a weft end according to the preamble of Claim 1 or 2.
  • Insertion devices on weaving machines are well known and are used to after entering the weft in the shed, the free weft ends in the then insert the following shed. This is often solved by the fact that The end of the weft thread is caught by the air flow of a blowing nozzle and into the open one subsequent shed is blown back. This forms on the Fabric edges a so-called insert edge, in which the Tissue about twice the thickness.
  • the insert edge has a width of a few to several centimeters.
  • the object of the present invention is to provide a method and an apparatus for Insert a weft end in such a way that it is essential wider insert edges can be achieved.
  • each pneumatically acting Insertion device not only has an insertion head, as is known hitherto, but at least two insertion heads in the weft direction of the thread are arranged one behind the other.
  • the insertion device according to the invention makes it possible to achieve a substantial degree insert longer thread end piece into the shed, so that a very wide Insert edge is formed. This increases the edge strength of the Fabric, which is required in many applications, and saves that cloth processing companies sewing the fabric edges around, so to speak to reproduce the insert edge.
  • the drawing figures show an example of a weaving machine, at the same time several webs of fabric can be woven.
  • the reed 1 consists of several sections, the fabric streets, i.e. the Areas in which no warp threads 7 are provided, each with one fixed filler 2 are filled. So it is a reed 1 and a reed Filler 2 arranged in an alternating order, being in the rear position of the reed 1, the filler pieces 2 are arranged in line with the reed 1.
  • the fabric runs over a continuous spreader table 3, the warp threads 7 Open a shed between the reed 1 and the spreader table 3.
  • a weft 5 is introduced into the shed via a main nozzle 4 and passes through this with the help of auxiliary nozzles 6 until it is on the opposite side arrives and is detected by a stretching nozzle 13.
  • a weft guard 14 checks whether the weft 5 has arrived correctly. Is the weft 5 arrived and was caught by the stretching nozzle 13, the reed 1 moves together with the stretching nozzle 13 in its front stop position, so that the Weft thread is struck on the fabric ( Figure 2).
  • each insertion head 8, 9 which, in Weft direction of the thread 5, as seen, are arranged one behind the other.
  • each a cutting device 10 which, after the reed 1 is in its forward position, the weft 5 cuts off.
  • the remaining remaining thread is disposed of by a suction device 12, the weft ends projecting above the fabric edges the insertion device 8, 9 is inserted into a shed following the previous shed.
  • the cutting devices 10 are located behind or in front of the outer ones Insertion heads 9 so that the cut off over the fabric edge protruding thread ends have a length x ( Figure 3) which is at least the Corresponds to the width of the insertion heads 8.9 one behind the other.
  • the insertion head 8 now takes over the weft end and places this pneumatically in a subsequent shed, whereby the forming insert edge has the previously defined length or width x.
  • Double the width of the insert edge When using two insertion heads 8.9 per insertion device, the Double the width of the insert edge. Three or more could be analogous successive insert heads are used, so that a three or multiply widened insert edge could be generated.
