International Classification:

US Classification:

Abstract:

A position indictor for an industrial sewing machine, particularly a programmable industrial sewing machine, in which an elongate slender member may be selectively extended through a tubular conduit to have an end of the member adjacent the work supporting bed so as to indicate to an operator the starting position for a work material from which stitching may initiate. The elongate slender member, which is best implemented by a wire, may also be used as an edge guide or a pivot point. Extension of the member through the flexible conduit may be initiated by an air cylinder or solenoid, and may be initiated by program control to take place when the sewing needle and the sewing machine presser foot are elevated.
