Abstract
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). 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) in the respective motion cycles (N) is closed, form an increasing or decreasing sequence.
