ABSTRACT:
A method and apparatus for automatically and continually feeding workpieces, one after another, to a sewing machine. The continuous feeding is imparted to the workpiece by a plurality of connecting links which connect the trailing edge of one workpiece with the leading edge of the following workpiece at a point in front of the sewing instrumentalities. The workpiece that is being fed into and through the machine automatically draws the succeeding workpiece towards and through the machine due to the connecting link fastening these two together. Motion is imparted to the connecting links by the feed device associated with the sewing machine. The connecting links are guided through a predetermined path by a rail system which automatically returns the connecting link to a staging area after same has been released from the workpiece. A sewing machine fastens together the continguous ends of the workpieces and a cutter cuts the chain formed therebetween.
