Definitions

  • the invention relates to a method for producing a warp knitted pile fabric using a warp knitting machine with a longitudinally displaceable pole board bar and at least five laying bars, one of which is a basic bar for forming a fabric base, e.g. Jersey, serves and lay the other bars as pattern bars at selected points in their working width, especially colored sample threads.
  • the displaceable pole board bar is described in DE-PS 24 35 312.
  • the invention has for its object to provide a method for producing a warp knitted pile fabric in which no pile of pile loops occurs. According to the invention, this is done in that in all pattern bars only every second perforated needle leads a thread and pairs are optionally formed from the pattern bars and within each pair the pattern bars are positioned in such a way that the threads of the other pattern bar of the pair occur instead of the threads omitted on a pattern bar , and that the pattern bars work together in such a way that the pattern bars of the one pair are offset according to a pattern and the threads forming the poles are placed over only one pile plate in each case to form pile loops, the pattern appearing through the pattern threads and the two pattern bars of a remaining pair are moved so that they lay the same goods base as the basic bar.
  • Pairing is now possible in many ways in the case of a warp knitting machine with four further pattern laying bars in addition to the basic laying bar, namely based on a designation of these four pattern laying bars with L2, L3, L4 and L5 in the following way: Couple 1 Pair 2 2 + 3 4 + 5 2 + 4 3 + 5 2 + 5 3 + 4 3 + 4 2 + 5 3 + 5 2 + 4 4 + 5 2 + 3
  • the method is expediently designed such that the threading of the threads through the perforated needles of the pattern laying bars extends essentially over the entire working width. Due to the extension of the guidance of the threads in the sense of occupying only every second perforated needle in all pattern laying bars, a uniform product image results, in which pile loops appear regularly across the entire product without omissions and without accumulations.
  • 1 shows the laying of five laying bars of a warp knitting machine, namely the basic laying bar L1 and the pattern laying bars L2, L3, L4 and L5, in a conventional, schematic representation. 1 also shows the movement of the displaceable pole board bar provided in the underlying warp knitting machine, shown on the movement of the pole plate P, which executes a reciprocating movement and is thereby offset by a needle pitch in each case.
  • the individual points of the transverse rows of points represent the individual knitting needle operations of the warp knitting machines, which are repeated per main shaft revolution of the machine, which is indicated by the in Longitudinal rows of dots are indicated.
  • corresponding further lines per knitting needle are indicated on the right next to the meandering line P by a thin drawing, which is intended to show the total movement of all the pole plates of the pole plate bar used.
  • the laying bar L1 carries out a laying forming a jersey fabric base, in which no pole is formed due to the offset of the pole board bar (see above-mentioned DE-PS 24 35 312). This arrangement is shown above the reference symbol L1.
  • the laying is repeated over all perforated needles of the laying bar L1, i.e. 1 about the laying shown in reference numeral L1 is repeated at every point, both in the transverse direction and in the longitudinal direction, since all perforated needles of the laying bar have been drawn in in a known manner for the formation of the jersey.
  • the laying bars L2 and L3 together form a pair, the laying bar 3 being positioned relative to the laying bar L2 such that, due to the fact that one perforating needle is left empty on the laying bars L2 and L3 and a corresponding positioning of these two laying bars with respect to one another, the piercing needles of the laying bar L3 are offset Place a stitch in each of the gaps left by the bar L2 and vice versa. This creates a full mesh of knitted goods. This can be seen from FIG. 1 by the fact that in the course 1 there is a distance of three courses between the drawn courses above L2 and L3.
  • a stitch laid by the laying bar L3 in the course 1 therefore follows the stitch in question from the laying bar L2 immediately to the right and to the left, which is indicated by the dashed lines L3 ', by which threads laid by the laying bar are represented. However, for reasons of clear presentation, these are only indicated by the dashed lines and are not continued over the entire FIG. 1.
  • the pattern bar L2 is laid out like the pattern bar L3, but with a course in the other direction.
  • the pattern laying bars L2, L3, L4 and L5 each receive specially colored pattern threads at selected points in their working width.
  • the laying rail L2 places a pattern thread shown in red above the reference symbol L2.
  • Such a common thread follows the bar L2 at the following 10th perforated needle if one wishes to obtain the pattern shown in FIG. 2, which will be discussed in more detail below.
  • the other perforated needles of the bar L2 are covered with threads of any basic color, for example in white.
  • the laying bar L3 receives a gray pattern thread and places it in the manner shown in FIG. 1. To create a symmetrical pattern, further gray pattern threads follow each of the 10th needle on the L3 bar. The remaining perforated needles of the laying bar L3 are then covered with sample threads of the same basic color as is the case with the laying bar L2.
  • the laying bars L4 and L5 receive a pattern thread in blue or green color, the remaining perforated needles being covered with pattern threads of the same basic color as in L2 and L3.
  • the exemplary embodiment shown is a deliberate simplification in order to facilitate the illustration.
  • several pattern threads of the same color can be drawn in side by side on a pattern laying bar (but always with the omission of a piercing needle), so that crossing strips result according to the pattern according to FIG. 1.
  • any number of further patterns can be created.
