Definitions

  • the invention relates to a weaving machine with a sley and a reed attached to it from elongated profiled slats, in which a guide channel for the weft thread to be inserted is incorporated, the guide channel having a trough-shaped cross section with a channel base parallel to the individual slats and substantially transverse to this running channel walls, and with a tissue support which ends at the height of the guide channel and which has a tissue guide surface at this end.
  • a fabric support is normally mounted near the stop line of the weft thread on the fabric edge, so that the fabric is in a somewhat defined position with respect to the reed and thus also the warp threads with respect to the weft insertion member of the weaving machine.
  • a design of the reed, as outlined at the beginning has prevailed.
  • the distance between the channel walls and the depth of the channel have values in the order of magnitude of 10 mm, and the fabric support is normally arranged next to the guide channel mentioned in the stop position of the sley for space reasons.
  • the fabric guide surface in the position of the sley closest to the fabric extends so far into the interior of the guide channel that the shortest distance between the fabric guide surface and the channel base is less than a third of the average distance between the channel walls.
  • the tissue is adequately guided if this distance is approximately 3 mm or less.
  • the tissue support has, at its end facing the tissue, a beak-shaped projection which projects into the guide channel during the leaf stop. The smallest distance between the fabric guide surface and the base of the channel will be 1 mm so that there is no contact between these parts in the event of deformation between the sley and the fabric support.
  • the tissue guide surface will compared to the guide channel is best adjusted so that the distance between it and the upper channel wall is of the order of 1 mm. Since the tissue is deflected by a small angle on the tissue guiding surface, it is advantageous to make it spherical.
  • the invention largely precludes relative movements of the fabric edge along the reed during the beating of the weft thread, as a result of which the weft threads are woven in more evenly and a regular fabric image is created.
  • Fig. 1 parts of the sley 3 the fabric support 40 with a screwed with it holder 41 and the fabric 1 to the left of the reed 31 and the warp threads 2a and 2b to the right of the reed 31 are shown, with the diagonally upwards or obliquely downwards warp threads 2a and 2b stretched below the shed 2 is formed.
  • the anchor point of the Weave on the fabric 1 in the channel base 33 is designated with P.
  • the reed 31 is screwed into the shop profile 34 by means of a clamping piece 35.
  • An auxiliary nozzle block 36 is also screwed to the shutter profile 34, from which an auxiliary nozzle 36a protrudes.
  • FIG. 1 the sley 3 is drawn in the position in which the channel base 33 has conveyed into the weft thread, not shown, up to the stop line P of the fabric 1. At this moment the fabric stop begins in a swivel of the sley to the left.
  • the end of the tissue stop is shown in FIG. 2, the end of the guide surface 42 facing the guide channel 32 being just in front of the guide channel 32.
  • the stop line P has moved somewhat downward along the channel base 33 in comparison with FIG. 1. Since the position of the stop line P on the channel base can vary slightly from stop to stop, there are different conditions for the weft threads to be struck in each case. This can lead to uneven weaving in of the weft threads and poor weave failure, especially with dense fabrics.
  • the fabric support in FIG. 3 has a beak-shaped projection 45, which results in a substantially enlarged guide surface 43 which extends close to the channel base 33 and is only a short distance from the upper channel wall 37.
  • the stop line P of the fabric lies here due to the relative positions of the guide surface 43, the upper guide wall 37 and the channel base 33 to each other just at the end of the arcuate transition between the upper channel wall 37 and the channel base 33.
  • the fabric support prevents the stop line P from slipping further below along the channel bottom 33, the arched transition 39 between the upper Channel wall 37 and the channel base 33 a sliding of the tissue or the stop line P in this transition area.
  • the fabric is thus in a precisely defined position at the end of the stop movement of the sley.
  • FIG. 4a an enlarged representation of a detail of the fabric and the warp threads 1 or 2a and 2b according to FIG. 3, the weft threads A, B, C, D, ... I drawn in white are each slightly smaller Measured up or down next to each other. They are wrapped in the black warp threads 2a, 2b, usually not every warp thread comes to lie alternately above and below one and the adjacent weft thread A, B in the usual weaves.
  • the weft thread I is conveyed from the position between the warp threads 2a, 2b within the shed 2 to the stop line P by means of the reed 31, during which it comes to lie somewhat above the previously weft thread H, since the lower warp threads 2b are essential are tensioned more than the upper warp threads 2a. Due to the strong weaving-in of the warp threads, the weft thread I later, like the weft threads A, C, E, G, will assume a higher position than the other weft threads B, D, F, H, so that it no longer has its higher position than the weft thread H. needs to change significantly. The situation is different with the next weft thread K to be entered and attached.
