    摘要: An apparatus for automatically aligning a workpiece along the line of feed is comprised of two pivotally interconnected arms extending transversely to the line of feed with each arm having a workpiece gripping element at one end thereof adapted to engage the workpiece adjacent an edge thereof. A solenoid is operatively connected to the opposite end of one of said arms for pivoting said one of said arms on the frame of a sewing machine to move the workpiece gripping element thereon into and out of engagement with said workpiece along a substantially vertical path. A servo motor operated eccentric is connected to the opposite end of the other of said arms for moving the workpiece gripping element thereon transverse to the edge of the workpiece along a substantially semi-oval path in opposite directions to periodically engage and shift said workpiece transversely to the line of feed. A photoelectric sensor is also provided for sensing the location of an edge of the workpiece and providing a signal for controlling said solenoid and said servo motor operated eccentric means.
