Abstract
A sewing machine for making edge-parallel shaping seams in multiple layer articles such as shirt collars comprises a reciprocating needle for sewing through the multiple layers of a workpiece such as a collar which has a plurality of edges disposed at angles to each other. The construction includes a guide fence having a guide edge extending alongside the needle. The material is guided against the guide edge. A feeder engages the workpiece from below a presser foot which is biased against the needle in a working position. The presser foot has an upwardly extending infeed end and a holddown member in the form of a strip element. It is adjustably supported above the workpiece and includes a front edge which is engaged downwardly on the workpiece and extends into the infeed end of the presser foot.
