Sewing machine with material cutting rolls

摘要

A sewing machine has improved material cutting before stitching. The machine includes a sewing head and stitch area where stitching of strip material occurs. Strip material is fed by a timing belt along a predetermined path of travel into the stitch area. A lower cutter roll is positioned along the predetermined path of travel, and the strip material passes over the lower cutting roll. The lower cutter roll is driven by a transmission system connected to the sewing head motor. At least one circular configured, freely rotatable rotary knife engages the lower cutter roll and any strip material passing thereover is cut before stitching.
