ABSTRACT:
A method for folding and stitching a shirt placket uses a remote placket forming assembly to facilitate formation of a shirt placket while a previously-formed placket is being stitched. To provide this operation, a transfer arm assembly supports the placket forming assembly at a location remote from the sewing machine of the apparatus. Following the formation of a placket on a first workpiece, the transfer arm assembly clamps and delivers the first workpiece to the sewing machine. Thereafter, the placket is clamped into a working position, and the transfer arm assembly is returned to its original position to receive a second workpiece. As the transfer arm assembly is returned, the sewing machine is actuated to stitch the previously-formed placket.
