摘要:
An elongated workpiece is transported forwardly and backwards in a sewing or stitching machine by looping it upstream and downstream of the sewing or stitching station, by maintaining both loops under tension, by increasing the size of the downstream loop simultaneously with a reduction of the size of the upstream loop, and vice versa.
