Basting stitch overthrow system |
摘要 |
A linear motor is used to jog the needle bar and gate beyond the normal jogging range in order to disable a latch and separate the needle bar from the sewing machine driving means. The linear motor is driven into this abnormal excursion beyond the usual jogging motion by supplying a known needle position signal to the servoamplifier system for the linear motor and providing a separate voltage from a regulated voltage source which is summed with the specific signal in order to provide sufficient electromotive force for jogging the sewing needle beyond the normal jogging range.
