Patent DE-3913022-A1 (DE)
Title: Thread-monitoring device for a sewing machine
Inventor: SHIBATA YOSHIO
IPC: B65H63/032
Filed: 1989-04-20
Abstract: A monitoring electrode (36) is arranged in the path of a thread (67) of a sewing machine. When a material is sewn by the sewing machine, a lower or an upper thread (67) moves spatially with respect to the monitoring electrode (36). An electric signal is obtained from the monitoring electrode (36) which responds to such a movement of the thread (67). Furthermore, a time signal transmitter (53) generates a signal which is synchronous with the vertical movement of a needle of the sewing machine. A differentiating device (54) receives the electric signal of the monitoring electrode (36) and the time signal of the time signal transmitter (53). The differentiating device (54) compares the electric signal with a reference signal, when a time signal is received, and emits a differentiating signal which corresponds with the result of the comparison. <IMAGE>
