Abstract
Sewing machine is modified to include means for feeding and cutting off slide fastener ladder as it is sewn directly to fabric. The means for feeding and cutting off include a pair of parallel blades one of which, the feed blade, is loosely mounted and biased downwardly so that when the assembly is depressed all the way forward, blade yields and cutter severs the ladder. Cam means are provided to drive the assembly in a rectangular path to engage the ladder element-by-element, pulling it through the sewing station. Override means are provided to momentarily stop the back-and-forth movement of the assembly and a depressor simultaneously urges the assembly down to accomplish the aforesaid severing.
