ABSTRACT:
A placket forming system comprises a double needle sewing machine with a cutter which cuts between the lines of stitching and a positioning apparatus including mechanically movable arms with gripping surfaces which operate in conjunction with the sewing machine and cutter apparatus. The positioning apparatus grips a work piece such as a shirt front placket assembly at the sewing machine work surface after the work piece has been sewn and cut and moves the work piece a predetermined distance along the work surface to a proper position under a cutting blade, and the cutting blade is actuated to make a crow's foot cut in the work piece at the end of the line of stitching in the work piece.
