Abstract:
1. A method of controlling a weaving machine for producing a woven fabric of warp threads, weft threads and at least one effect thread, wherein each said effect thread forms interlacing points at which said effect thread crosses behind respective ones of said weft threads on a back side of said woven fabric and crossing points at which said effect thread crosses over in front of respective ones of said weft threads on a front side of said woven fabric, wherein respective ones of said interlacing points are spaced apart from one another with a respective plurality of said warp threads therebetween in a weft direction of said woven fabric, and wherein said method comprises steps: a) specifying a pattern repeat area for said woven fabric, wherein said pattern repeat area extends in said weft direction and in a warp direction of said woven fabric and represents a pattern repeat of a weave pattern of said woven fabric, wherein said weave pattern comprises successive weave pattern rows successively after one another in said warp direction, and wherein said weave pattern rows include interlacing weave pattern rows that respectively include at least a respective one of said interlacing points in said pattern repeat; b) producing plural data sets including a respective interlacing data set for each respective one of said interlacing weave pattern rows, wherein each said interlacing data set includes plural data values comprising a first data value derived from a weft sequence number of a respective one of said weft threads behind which said effect thread crosses at said respective interlacing point, a second data value derived from a position of said respective interlacing point in said weft direction in said pattern repeat, and at least one further data value derived from said weave pattern; c) forming, with said plural data sets, a pattern draft for said weave pattern; d) storing said pattern draft in a data storage medium; and e) using a control device of said weaving machine, reading out said data values of said data sets of said pattern draft from said data storage medium, and in accordance with said data values controlling a weaving operation of said weaving machine to produce said woven fabric.
