ABSTRACT:
A sewing unit with a feed device for a fabric holder with support elements that can be moved along a guide and are connected to a drive each for feed means acting on the fabric holder. A fabric being sewn can be transported to or removed from the sewing machine by the feed device over any desired distance and the feed movement of the fabric being sewn can be brought about without problems during passage through the stitch formation site of the sewing machine even at very high stitch frequency because of the favorable dynamic properties. The guides are arranged in the same direction, and the support elements can be driven synchronously for a movement of the fabric holder in parallel to the guides, and at mutually different velocities for a movement in a direction deviating from the direction.
