<p>This invention involves a pallet for use in automatic stitching machines which insures proper registration of a workpiece with respect to the stitching instruments and maintenance of such registration during machine operation. Basically, the pallet is constructed of two outer plates hinged together to form a sandwich type arrangement having openings therein to allow for access of the stitching instruments to the workpiece. These openings are generally identical and are accurately located with respect to the stitching instruments. In the interior of the pallet means are provided for removably securing the workpiece in accurate registration with the stitching instruments. The access openings may be designed to receive overlay or overlapping portions of a composite workpiece and additional outer or interior plates may be provided to accommodate a wide variety of workpieces. The pallet is removably secured to the supporting carriage of the automatic stitching machine in a position which is fixed in relation to the stitching head.</p> |
