发明名称 Sewing aid device
摘要 A sewing aid device, particularly for inserting slide fasteners, collars, sleeves and the like into partly-finished garments, comprises a frame in which the materials to be sewn together are held in fixed relative position. A guideway on the frame cooperates with corresponding means on a sewing machine foot so that the machine sews around the guide without the need for constant operator adjustment.
