ABSTRACT:
A workpiece holder which is attachable to positioning apparatus associated with the sewing head of an automatic sewing machine whereby the workpiece holder can be automatically positioned with respect to an automatic reciprocating needle in the sewing head so as to allow a workpiece held within the workpiece holder to be sewn. The workpiece holder is adapted to hold cording to be disposed in the workpiece by stitching thereby to give a corded effect to the stitch pattern. The workpiece holder includes a base plate having at least one open stitch area being defined by edges within the base plate and arranged to hold a workpiece to be sewn. At least two rows of posts are disposed on the base plate, each of the rows being disposed adjacent to opposite edges of the stitch area. A cover plate is pivotally attached to the base plate. The cover plate has an open stitch area corresponding in location to the open stitch area on the base plate. An opening is formed in the cover plate to receive the rows of posts so the cover plate can be closed flatly upon the articles being worked upon. A mechanism is disposed on the base plate for attaching the base plate to the positioning apparatus of the automatic sewing machine.
