Title: Thread cutting device for sewing machine
Inventor: SHIMIZU MASAKI
IPC: D05B65/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a thread cutting device for a sewing machine, having the capability of stabilizing thread cutting operation, by driving a thread cutting mechanism with a dedicated actuator. SOLUTION: A control means controls an actuator so as to cause a thread cutting mechanism to operate synchronously with a main shaft (step S110). Thus, the actuator drives the thread cutting mechanism independently of a sewing machine motor, and thread is cut with the thread cutting mechanism. In other words, the moving cutter of the thread cutting mechanism always moves synchronously with the main shaft, even upon the occurrence of the irregular rotation of the main shaft, thereby stabilizing thread separation. In addition, the cutting timing of a needle thread loop formed on a hook becomes stable and a needle thread remnant after cut can be stabilized.
