Definitions

  • the invention relates to a method for producing carpets woven as a double piece, in which the figures are formed by so-called pile warp threads, which run from the upper fabric to the lower fabric and vice versa and at the moment when the pile threads move from one fabric to the other run, are distinguished as working or figure-forming pole (pattern-forming pole), while the non-working pile threads are called dead pole (dead chore).
  • the invention relates in particular to a method for weaving on a single or double rapier loom with the exclusion of the weft of a double piece fabric (alternately one weft in the upper and lower compartment) as a result of the single-coil binding (or with single-compartment weft insertion).
  • FIG. 1 illustrates, which schematically represents a single-coil weave (or weft weave) of a double piece fabric.
  • a weft thread (1) is inserted alternately into the lower fabric (OW) and the upper fabric (BW).
  • the weft thread (1) is located under the tension warp thread (SO) of the lower fabric (OW).
  • the weft thread (1) is located above the tension warp thread (SB) of the upper fabric.
  • the weft thread (1) is located above the tension warp thread (SO) of the lower fabric (OW).
  • the weft thread (1) is located under the tension warp thread (SB) of the upper fabric (BW).
  • these pile warp threads can take two positions.
  • pile warp thread does not make a connection between the lower fabric (OW) and the upper fabric (BW), i.e. it appears as a dead pile
  • this pile warp thread participates in the binding of the lower fabric OW or the Upper fabric BW, so that one speaks of an integrated pile warp thread or briefly of an integrated, dead pile.
  • the choice is between remaining as an integrated pile warp thread or as a working or figure-forming pile warp thread for a connection e.g. of the two fabrics OW and BW or BW and OW after the weft 2.
  • a pile warp thread - for example P1 - is effective as a working pile in weft 1
  • this thread P1 is brought under the weft thread, while the other pile warp threads are passed over the weft thread .
  • the pile warp thread P1 will be placed over the weft thread, while the other pile warp threads are brought under the weft thread.
  • This single-coil binding has the disadvantage that it shows so-called double processing ("double workers").
  • double workers In the transition from a certain color, which is formed by a figure-forming pile warp thread, which is incorporated after the transition, e.g. in the upper fabric, to another color, which is formed by a figure-forming pile warp thread, which occurs before that transition in the opposite fabric (lower fabric ) was involved, a piece of the ending color merges with the beginning color (see shots 15 and 16 of Figure 1). These two pieces of pile thread of different colors will lay together (in the weft direction) and will Called double workers. The dividing line between these two color fields is indistinct and shows some interlocking.
  • a double plush fabric weave is shown without a double worker.
  • One of the two pole loops, which otherwise form the double worker, has been left out.
  • a color point is provided on the card drawing for 4 shots (2 shots per carpet), corresponding to the repeat of the basic weave of 4 shots.
  • the object of the invention is a method of weaving a double-piece pile fabric, furthermore in particular a weft weave according to a single or double-spool weaving process with elimination of a weft with the aim of excluding double workers, combined with a pattern fineness of 1.5 weft per carpet and color point in the map drawing.
  • the procedure for producing a double-piece carpet fabric, in particular in a single-coil weave is further to place the working repeat for the pile warp threads on 3 wefts (1.5 wefts per carpet), while the working repeat of the basic weave is over 4 wefts (2 wefts extends per carpet).
  • Figure 1 is a schematic representation of a single-spool 1-weft binding on the double piece with double worker.
  • Figure 2a is a schematic representation of a single-spool 1-weft weave on a double piece without Duplicate worker, with a pattern fineness of 2 shots per carpet, which is described in European Patent No. 175,963.
  • FIG. 2b is a schematic illustration of a 1-weft weave woven as a double piece with double bobbin, with the elimination of the weft without a double worker, a pattern fineness of 2 wefts per carpet being present.
  • FIG. 3a is a schematic illustration of a 1-weft weave woven as a double piece in single-spool according to the invention.
  • FIG. 3b is a schematic illustration of a 1-ply weave woven as a double piece with a double bobbin, with elimination of a weft according to the invention.
  • Figure 4 is a representation of a decision scheme for choosing a manchon.
  • FIG. 5 contains tables for the correspondence between the manchons used and the desired positions of the pile warp threads.
  • FIG. 6a is a schematic illustration of a particular situation in which a pile warp thread forming figures is placed on the upper fabric without forming figures on an intermediate repeat pattern.
  • FIG. 6b is a schematic illustration of the previous situation, in which the pile warp thread involved, which does not form figures, is nevertheless tied in on an intermediate weave repeat on the third weft of this repeat.
  • FIG. 6c is a schematic illustration of a situation in a lower fabric which corresponds to that in FIG. 6a for the upper fabric.
  • FIG. 6d is a schematic representation of a solution for the lower fabric, which corresponds to that of FIG. 6b for the upper fabric.
  • Figure 7 is a flow chart for the choice of the manchons.
  • weft With every odd-numbered weft (1, 3, 5, ...) the weft (IB1, IB2, ...) is in the upper fabric. With weft 1, 5, 9, 13, ... the weft is above the tension warp thread (SB), while with weft 3, 7, 11, ... the weft is under the tension warp thread (SB).
  • the pile warp thread (P1) forms the figures in the weft (1, 2, 3) and is in the weft (4, 5, 6), ( 7, 8, 9), ... bound in the upper fabric;
  • the pile warp thread (P2) is in the weft (1, 2, 3) in the lower fabric involved, forms figures when weft (4, 5, 6) and is again integrated into the lower fabric when weft (7, 8, 9, 10, 11, 12, ...);
  • the pile warp thread (P3) is bound in the weft (1, 2, 3) and (4, 5, 6) in the lower fabric, forms figures in the weft (7, 8, 9) and is in the weft (10, 11 , 12) again integrated in the lower fabric.
  • Repeat A has B / BW - B / OW - O / BW
  • Repeat B has O / OW - B / BW - B / OW
  • Repeat C has O / BW - O / OW - B / BW
  • Repeat D has B / OW - O / BW - O / OW.
  • the position to be occupied by the pile warp threads in a specific work report depends on the position of the pile warp threads during the previous repeat either in a pile forming a figure or in an integrated position or in the work report A, B, C or D.
  • the figure-forming pile warp thread (P1) is provided for integration into the upper fabric (BW)
  • the previous work report not forming any figures i.e. it was a canvas
  • the work report A and thus the manchon (21 ) are to be used (see the table in FIG. 4).
  • the figure-forming pile warp thread (P2) is provided for binding in the lower fabric (OW).
  • the previous repeat formed a pile but a different pile warp thread, which was intended for its integration in the upper part, and this is done on the work repeat B. Then the manchon (18) must be used (see FIG. 4). There is no double worker between shot 2 and 3.
  • the figure-forming pile warp thread (P3) is provided for binding in the lower part, while the previous repeat formed a pile but of another pile warp thread, which was now intended for binding in the lower part in the work repeat C. , for which the manchon (15) is then to be used (see FIG. 4).
  • the figure-forming pile warp thread (P1) is provided for binding in the upper fabric, while the previous work repeat also formed figures with another pile thread, which is now also provided in the work repeat D for binding in the lower fabric for which the manchon (32) is to be used (see FIG. 4).
  • the positions of the other pile warp threads which correspond to the different manchons can likewise be read from FIG. 5 in the same way.
  • the other possible pile warp threads are (see table in FIG. 5): the previous figure-forming pile, the pile warp thread (PIOW), which is integrated into the lower fabric, if this is not the present or previous pile warp thread forming figures, the pile warp thread (PIBW ), which is bound in the upper fabric if this is not the current or previous figure-forming pile warp thread.
  • FIG. 6b The elimination of this error is illustrated in FIG. 6b for the integrated pole which lies above the upper fabric in the weave repeat A.
  • the integrated pole is integrated in that it is placed under the weft 3 of the binding repeat A.
  • This solution is achieved systematically as follows: After using the various manchons illustrated in FIG. 5, the binding obtained is checked for the presence of pile warp threads, which are located five consecutive shots above the weft. In these five successive shots, the third weft is then modified from these five, the pile warp thread in question thus being brought under the third weft and thus being well integrated.
  • FIG. 6d The elimination of this error is illustrated in FIG. 6d for the integrated pole, which lies below the lower fabric in the weave repeat B.
  • the integrated pole is integrated in that it is brought over the weft 3 of the binding repeat B.
  • This solution is achieved systematically as follows: After using the various manchons illustrated in FIG. 5, the binding obtained is checked for the presence of pile warp threads which are five consecutive wefts below the weft. In these five successive shots, the third weft is then modified from these five, the pile warp thread in question being brought over the third weft and thus being well integrated.
  • the advantage of working according to the invention generally consists in the fact that there are no duplicators in the two double-piece fabrics produced, while the pattern fineness is increased, while the same weaving speed can be maintained as before.
  • the number of color dots in the map drawing of the carpet corresponds to a third of the total number of shots and thus the number of shots divided by 1.5 per carpet.
  • a predetermined map drawing can easily be converted into a command sequence (impact cartridge) for the specialist movement of the pile threads are implemented while avoiding duplication of work.
  • This implementation can also be carried out automatically, e.g. with the help of electronic data processing equipment.
