ABSTRACT:
A loom is slowly operated in reverse rotation to move the loom to a position where a cutter is able to easily cut an improper weft when there occurs an error in the picking motion. Then, the loom is operated in normal rotation to move it to a position where the improper weft remaining in the shedding motion can be easily removed. A pick finding device is then operated to temporarily separate a main shaft and the shedding motion, and a harness frame is reversely rotated for 360.degree.. A new weft is then inserted after the improper weft is removed from the shedding motion. In the course of the operation, a cloth fell is held at a fixed position to protect the cloth fell from being beaten by a reed. The take-up motion is then operated in normal rotation, and at the same time the let-off motion is rotated in the reverse direction at a fixed rotational ratio to provide a warp with proper tension. Thereafter, the loom, take-up motion and let-off motion are simultaneously started for restarting the weaving operation.
