ABSTRACT:
In order to prevent the formation of weft streaks in cloth when a loom is restarted after a stoppage, the warp tension is reduced by a predetermined amount as soon as the stoppage occurs and the original warp tension is restored before restarting. The reduction in the warp tension prevents the tensile failure, that is, the plastic extension of the warp yarn, and ensures the exact repositioning of the beating-up line of the weft upon restarting.
