Definitions

  • the invention relates to a reed (Riet) for air jet looms according to the preamble of claim 1.
  • the invention is based on a reed according to DE 41 31 167 A1, the reed being divided into a number of partial reeds. There is a gap between the reeds, a so-called reed filler is arranged in the area of the reed gaps, which is approximately the same as the reed. Through the reed filler, the ventilation properties of the weft insertion channel of the reed are simulated, i.e. H. the weft insertion channel continues in the reed fill pieces.
  • an edge or step forms in the transition area between the individual sections of the weft insertion channel, which can disrupt the movement of the blown weft thread through the weft insertion channel or the weft thread can get caught on such an formed edge can.
  • the invention has for its object to develop a reed of the type mentioned in such a way that an impairment of the weft inserted in the transition area between individual reed sections is avoided.
  • the individual sections of the weft insertion channel assigned to the partial reeds or the reed filler pieces are designed in such a way that no step can form in the transition area between one section and the next against the weft direction. This is achieved in that the transition region between a section of the weft insertion channel and the subsequent section of the latter is at least partially funnel-shaped against the weft direction.
  • the funnel-shaped widening of the thread entry areas of the respective reed sections allows certain tolerances in the position adjustment of the partial reeds or filler pieces, since an annoying step formation in the weft insertion channel can no longer occur.
  • the weft insertion channel is approximately U-shaped and it is provided that all three wall regions of the weft channel are expanded in a funnel shape.
  • weft insertion channel is widened only in the vertical direction or only in the horizontal direction.
  • the dimensions of the firing channel are relatively small, so that the expansion of the Channel moved on the order of a few millimeters.
  • Figure 1 shows a schematic view of a reed, which consists of an alternating arrangement of partial reeds 1.1a and reed filler 2.2a.
  • weft insertion channel 3 that extends across the entire width of the reed.
  • the weft thread 5 is blown into the weft insertion channel 3 through a main nozzle 4 and passes through the entire weft insertion channel 3 up to the opposite side of the reed.
  • FIG. 2 shows the transition area between a partial reed 1 and a reed filler 2 of a reed according to the prior art.
  • the continuous weft insertion channel 3 can be seen, two sections 8, 9 of which are shown here. Due to inaccurate adjustment of the reed sections 1, 2 or signs of wear, it often happens that the sections 8, 9 of the weft insertion channel 3 are no longer aligned with one another, so that an edge forms in the entrance area of section 9 of the weft insertion channel, on which the registered weft 5 can get caught in the worst case. This results in an error message from the shot monitoring and the machine comes to a standstill.
  • the weft insertion channel for the weft thread 5 always represents a free passage, since edges or steps, as shown in FIG. 2, can no longer occur. In particular, there can be no edges or steps that are formed counter to the weft direction.
