METHOD FOR CONTROLLING SHED OPENING OF PILE WARP YARNS IN PILE FABRIC LOOM

摘要

There is provided a method for controlling shed opening of pile warp yarns in a pile fabric loom. The pile fabric loom includes a plurality of heald frames through which the pile warp yarns are passed, and a plurality of drive devices driving the respective heald frames and forms piles by forward and rearward movement of cloth fell. The method is characterized by setting a shed opening amount of the pile warp yarns at a start of weft insertion in fast picking larger than a shed opening amount of the pile warp yarns at a start of weft insertion in loose picking.
