ABSTRACT:
An apparatus for setting a zipper and a front cloth to sew in correct position providing a pair of set-plates which perform three dimensional motion: vertical swing to clamp a workpiece and horizontal swing to form a "V" shape to receive a slitted front cloth and forming parallel lines to locate the zipper and the front cloth in the correct position. The motion of the set-plates is driven by air cylinders actuated by a pedal switch.
