Abstract
A sewing-material workpiece holder for holding and positioning the sewing part. The workpiece holder is movable in the longitudinal direction of the sewing-machine arm and also in a direction transverse thereto. The holder is connected in form-locked manner via a toothed drive to a carrier. The toothed drive includes a toothed drive member mounted on the carrier, and a rack which is mounted on the sewing-material holder, the rack being in engagement with the toothed drive member when the workpiece holder is mounted on the carrier. The drive member is driven by at least one motor. The holder is locked to the carrier by a guide block or clamp which is swingably mounted on the carrier and swingable into a lower, locking position. A predetermined positional association of the sewing-material holder with the carrier is made possible by an alignment device on the carrier.
