发明名称 Presser foot for sewing machine
摘要 A presser foot is for a sewing machine features a sole (14) which lies on the workpiece and applies force on the workpiece. The sole side (16) facing the workpiece has a layer with material (plastics) that reduces the friction resistance against feeding the piece. The layer incorporates a support plane (21) which is positioned in relation to the feed dog (31) in such a way that it comes into contact with the feed dog (31) in the absence of the workpiece. The wear resistance of the support plane (21) is several times that of the layer of the sole underside.
