摘要： 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.

摘要： Fabric lengths are monitored during and/or prior to sewing by sensing means in conjunction with a logic system. Differences in fabric ply lengths are compensated for by the logic systems control via stepping motors of the differential feed assembly located above and below the fabric plies.

摘要： a sewing machine apparatus for aligning one side of a series of fabric panels in a predetermined position. The apparatus includes measuring devices which associate with and continually monitor the position of one side of the fabric panels with respect to each other. A control means, responsive to the output of the measuring means, selectively advances or retards the top feeding mechanism engaging with the top layer or fabric or the bottom feed mechanism engageable with the bottom layer of fabric, as may be necessary, whereby aligning one side of the fabric panels at the completion of the sewing operation.
