Abstract
The disclosed method and apparatus for setting a workpiece correctly on a skirt-zipper sewing machine provides a pair of pressing plates which are positioned at the center of a zipper when the plates are lowered and which press the material of the workpiece and the zipper to be sewed to it. Each pressing plate works as a guide to set the to-be-sewn section of the workpiece at the center line of the zipper. The plates are then rasied and again lowered to press the workpiece so that shrink marks that occur in bias curved sections of the workpiece are stretched. In this manner, a zipper is sewed to the workpiece without shrink marks.
