Arrangement of a thread take-up lever in a sewing machine.

摘要

A thread take-up lever in a sewing machine in which the driving curve disc (17) of the take-up lever is mounted on the crankshaft (10) driving the needle bar up and down. Because the driving curve disc is merely supported on one side, the spacing on the other side can be fully utilized. This provides for a correct position of the thread take-up movement from a pattern point of view. To avoid play between the curve (17) and the curve follower (25), the curve has chamfered side walls and the curve follower has a tapered, blunt tip.
