Abstract
When a sewing machine is locked during stitching of a thick fabric, the rotational direction of a sewing motor is alternately reversed at a predetermined time interval. A needle operatively coupled to the sewing motor through a mechanical system is moved up and down, whereby the needle sticks into the same stitching point for a desired number of times.
