Abstract:
1. Method for shed formation on a weaving machine ( 2 ), which is driven by a main motor ( 3 ), with a shedding device ( 4 ), which is driven by a shedding motor ( 5 ), wherein, in each motion cycle (N) of the weaving machine ( 2 ) a loom shed ( 7 ) formed by warp threads ( 8 ) of the weaving machine ( 2 ) is opened and closed dependent on a weave pattern, and wherein the synchronicity of the two motors ( 3 , 5 ) is controlled by signals ( 10 ) of a control device ( 9 ), characterized in that during a partial number (Tn1, Tn2) of motion cycles (N) the synchronicity of the two motors ( 3 , 5 ) is changed in such a manner so that plural shed closure angles (FSW), at which the loom shed ( 7 ) is closed in the respective motion cycles (N) form an increasing or decreasing sequence, and further characterized in that a prescribed total number (Ng) of motion cycles (N) contains both a first partial number (Tn1) of motion cycles (N) in which plural shed closure angles (FSW) form an increasing sequence, as well as a second partial number (Tn2) of motion cycles (N) in which plural shed closure angles (FSW) form a decreasing sequence.
