A device and method to be used prior to stitching a work piece, that will automatically align both the leading edge and the margin edges of the work piece, and locate the aligned work piece correctly at the stitch forming location. The method and apparatus include loading a ply into a sewing area and sensing the leading edge via first sensor (5) which when sensed is moved by a gripper wheel (4) perpendicularly toward a second sensor (10) which stops the wheel. The material is then moved forwardly with a feeding wheel (13) until sensed by a third sensor (11) and then is stopped. The same procedures are performed to a second ply using a second gripping wheel (2) and second feeling roller (14) and fourth (3), fifth (9) and sixth (12) sensors. When the plies are located, the presser foot (164) is lowered and sewing is commenced.
