Abstract
A workpiece guide device on a sewing machine serves for the automatically controlled alignment of a workpiece, with respect to its edge, for the purpose of sewing along the edge of the workpiece at the correct distance from that edge. The circumferential side of a motor-driven guide wheel (36) carries wheels (34) which are likewise motor-driven and which guide the workpiece transversely to the direction prescribed by the guide wheel (36).
