PROBLEM TO BE SOLVED: To make weft yarn density unevenness (weaving bar) produced with changeover of elements related to weft yarn constraint force less conspicuous in a loom for the changeover thereof during weaving operation. SOLUTION: The loom 1 runs warp yarns 3 by driving warp yarn running members (3 and 13) by a speed command signal. In the loom, the signal of the speed command for the warp yarn running members (3 and 13) is corrected to a direction to eliminate the weft yarn density unevenness produced with the changeover when changing over the kind of weft yarns as the elements relating to the weft yarn constraint force.
