Abstract

For weaving pattern formation of a woven fabric with weft threads (3), warp threads (1) and effect threads (2), data sets (20) are produced according to a method in which data values are derived from weft sequence numbers (30) and from positions of interlacing points (P) of an effect thread (2) with the weft threads (3) in the pattern repeat (29). These data sets (20) are supplemented by further data values (31, 32, 33, 34) derived from the weaving pattern, in such a manner so that they form a pattern draft (28) for a weaving pattern with additional weft effects. In a weaving machine with devices for slidingly displacing effect threads (2) in the weft direction (12), the weaving pattern formation is derived from the data sets (20) of this pattern draft (28).

Claims

1. Method for producing data sets (20) for weaving pattern formation of a woven fabric with additional weft effects, which consists of weft threads (3), warp threads (1) and at least one effect thread (2), wherein the effect thread (2) forms interlacing points (P) with the weft threads (3), which lie on the back side of the weft threads (3) in the woven fabric (26), as well as crossing points (K), which lie on the front side of the weft threads in the woven fabric (26), wherein the weaving pattern is of the type that interlacing points (P) are present, between which several warp threads (1) lie, wherein a woven fabric area is specified, which represents a pattern repeat (29) and which extends in a weft direction (12) and in a warp direction of the woven fabric (26), and wherein the producing of the data sets (20) is characterized in that for each position of an interlacing point (P) in the pattern repeat (29) a data set (20) is produced, which is comprises several data values, wherein a first data value of the weft sequence number (30) is derived from a weft sequence number of the weft thread (3) of this interlacing point (P) in the pattern repeat (29), while a second data value of the additional weft effects (DS) is derived from the position of the applicable interlacing point (P) in the N weft direction (12) of the pattern repeat (29), and that the data sets (20) are supplemented by further data values (31, 32, 33, 34) derived from the weaving pattern, so that the data sets (20) form a pattern draft (28) for the weaving pattern, and that these data sets (20) are stored a in a memory means (22) of a control device (8) of a weaving machine.
