Abstract
In a sewing machine, immediately after every thread trimming, the electric motor is reversely rotated for a predetermined angle, hence reversely rotating the sewing mechanism, so that the needle bar is brought up to its upper dead point when the electric motor is stopped after the thread trimming, and, thereby, there is no fear of spoiling the object cloth by the needle tip. The predetermined angle is controlled by processing an output signal of a speed detector.
