摘要

A sewing machine with a thread cutter for the face thread features a shifting knife with two cutting points and a clamping installation for the thread guided through the needle eye. The knife takes the form of a knife plate that moves between two end positions. The plate incorporates two stitch holes, between which a knife stem is formed. Specifically the clamping installation features a calmping spring which lies on the knife stem and is equipped with a stitch hole. The knife glides on a stationery cutting plate which is equipped with an opening. The knife-side edges of the opening are equipped with cutting edges which act in conjunction with two cutting edges of the cutter.
