Definitions

  • the invention relates to a reed for a jet loom, in which the weft threads are introduced into the shed by means of a gaseous medium which is arranged at intervals over the weave width and is periodically immersed in the shed; with at its edge facing the nozzles having a profile and in its entirety forming a guide channel for the weft thread, the first profile teeth being formed by a semi-open, approximately U-shaped recess with two side edges and a transverse edge connecting them.
  • the first leaf teeth have two nose-shaped projections on one edge, between which the U-shaped recess lies.
  • the recesses of all leaf teeth form the guide channel mentioned.
  • the invention is intended to reduce the stress on the warp threads at least to such an extent that no marking can be seen in the fabric.
  • the invention is based on the new finding that it is not the nozzles that are solely responsible for the stress on the warp threads, but rather the interaction of the nozzles with the adjacent leaf teeth.
  • the invention is characterized in that in the region of the projection of the nozzles onto the reed, second leaf teeth are provided, which on one edge have a shape that deviates from the profiling of the first leaf teeth and is selected such that the guide channel is additionally at least on its through the side edges of the recesses of the first leaf teeth adjacent to the nozzles are open.
  • the reed 1 shown in FIG. 1 is intended for use on an air jet loom and has a guide channel 2 for the weft threads to be inserted.
  • the weft insertion takes place through a main nozzle 3 arranged on the side of the warp threads, through which a weft thread fed in the insertion direction A is blown into the guide channel 2, and through projecting close to the guide channel 2, driven synchronously with the reed 1 and periodically inserted into and in the warp threads auxiliary nozzles 4 emerging from them.
  • This arrangement of auxiliary nozzles 4 is known and is not described in detail here; in this connection reference is made to US-A-3 818 952.
  • the reed 1 consists of an upper and a lower frame rail 5 and 6 and first and second leaf teeth 7 and 8, 9, which are framed by the frame rails at the ends.
  • first and second leaf teeth 7 and 8, 9 which are framed by the frame rails at the ends.
  • FIG. 1 two variants of the reed 1 are shown, both of which Variants of the first leaf teeth 7 each have an upper and a lower projection 10 and 11 respectively.
  • the second leaf teeth 8 have only one upper projection 10
  • the second leaf teeth 9 in the exemplary embodiment shown in the right half of the figure have no projection and are straight.
  • the first and second leaf teeth 7 and 8, 9 are shown individually.
  • the projections 10, 11 of the leaf teeth 7 and 8 are located on the longitudinal edge of the leaf teeth facing the tissue stop edge during operation.
  • the inner edges of the projections 10, 11 form the side legs of a U-shaped recess 12, which recesses in their entirety form the guide channel 2 of the reed 1.
  • the cross leg 13 of the recesses 12 is aligned with the front edge of the straight second leaf teeth 9 facing the tissue stop edge or with the corresponding straight front edge of the profiled second leaf teeth 8 lying below the projection 10.
  • the shot stop is carried out by the cross leg 13 of the first leaf teeth 7 and through the corresponding area of the second leaf teeth 8 or 9.
  • the second leaf teeth 8 and 9 are each arranged in the reed 1 at the locations of the projection of the auxiliary nozzles 4 onto the reed 1, or in other words, in the immediate vicinity of the tips of the auxiliary nozzles 4. This means that those who dive into and out of the shed are Auxiliary nozzles 4, due to the lack of the lower projections 11, ensure that the warp threads run more freely between the reed 1 and auxiliary nozzles 4, as a result of which the warp threads are moved by the auxiliary nozzles 4 and are less stressed by the reed 1.
  • the area with the second leaf teeth 8 and 9 is in each case around the tip of the auxiliary nozzles 4; the length of this area is in each case a few, preferably about 2 to 3 mm.
  • the guide channel 2 instead of by leaf teeth 7 with two projections 10 and 11 and a recess 12 by leaf teeth in the manner of the second leaf teeth 8 with only one projection.
  • the leaf teeth would be assembled in such a way that the projection would alternate between the top and bottom, which would also result in a guide channel 2.
  • only second leaf teeth 8 or 9 would also be arranged here, and in this case, as in all other applications, both types of second leaf teeth 8, 9 could also be mixed in the areas mentioned.
  • the guide channel 2 in the region of the auxiliary nozzles 4 is open at least on its wall adjacent to the auxiliary nozzles 4.
  • This wall does not have to be the lower wall as in the figures, but it can also be the upper wall if the auxiliary nozzles are inserted into the warp threads from above.
