Abstract (en)

When weaving operation is stopped due to a weft insertion failure, the loom is driven in a backward direction so that pick finding is conducted and a defective weft yarn is removed. After that, the loom is reset to a start state. In this case, a shed is formed in accordance with a correction pattern SKsj (j=1, 2...) instead of a regular shedding pattern SKi. By setting the shedding size of the correction pattern SKsj to <MATH> the warp yarn is not in excessively large tension. In this manner, weft yarns woven into a fabric before the occurrence of weft insertion failure are not undesirably moved, thereby keeping the density of weft yarn uniform, and preventing filling bar in the fabric. <IMAGE>
