ABSTRACT:
A workpiece holder for sewing machines in which a plurality of supporting segments are located next to one another and are displaceable relative to each other. These supporting segments have a rim zone at which needles are located. The rim zone, furthermore, supports the edge of a workpiece to be processed. A device which may be lowered onto the workpiece, cooperates with the needles for holding the workpiece on the needle. A contour adjusting device is provided with templates for shifting the supporting segments. The templates have a contour corresponding to the seam to be applied to the workpiece. The supporting segments are, moreover, formed by rails having a U-shaped cross-section with cross bars carrying the workpiece and having recesses for permitting passage of the needles. The latter are arranged on a two-arm lever rotatably supported in each of the supporting segments, and they are held in a position permitting passage through the supporting segments within the recess by means of a spring.
