Garment section clamp for sewing machine - esp for pockets, preventing unfolding when folder plates withdraw

摘要

In a garment section clamp for a sewing machine, a centre section comprising two plates lying one above the other and having a sliding folder plate between them, works with the folder plates of an outer frame, and has the lower plate of the centre section, larger in outline than the upper plate, and milled on its under-surface, at its leading edge, so that it can press and grip securely the under-section of the pocket edge. Method prevents the tendency of certain forces to unfold when the folder plates are retracted, without additional devices.
