ABSTRACT:
A picking period setting device for a loom to decide an appropriate picking period for satisfactory picking operations. A shedding curve calculating circuit is used which calculates shedding curves representing the shedding motion of heddle frames. A shedding stroke calculating circuit calculates a set of desired shedding stroke curves. An appropriate picking period deciding circuit decides a precise picking period defined by the crank angles of the loom on the basis of the result of comparison of the shedding curves and the desired shedding stroke curves. Thus, the weaving operation of the loom is continued without interruptions caused by faulty picking.
