ABSTRACT:
An auxiliary transport device for sewing machines utilized to attach bands to the edge of a workpiece having a pair of spaced roller members disposed in frictional engagement with a band attached to the workpiece and simultaneously rotated incrementally for advancing the workpiece away from the sewing zone. A compensating roller is mounted co-axial with one of the pair of spaced roller members and incrementally rotated therewith in a location to frictionally engage and advance that portion of the workpiece extending from the band. The compensating roller is capable of yielding in a vertical direction without effecting the position of the roller with which it is operatively associated and provides a means for effectively accommodating portions of the workpiece varying in thickness as a result of attachments such as loops, pockets and the like.
