ABSTRACT:
A sewing machine for forming stitch patterns on a fabric comprising a select key, an input key, a cessation signal generator, and a controller. Stitch pattern data for desired stitch patterns are chosen from a large number of stitch pattern data stored in a memory by the select key, and arrangement data, comprising arrangement direction data, arrangement number data, and margin space data, for the stitch patterns are entered via the input key. The sewing machine forms arranged stitch patterns on a fabric by relative movement between a needle and a fabric holder. When some accident, such as thread breakage and needle breakage, occurs, during the stitch pattern formation, the signal generator issues a cessation signal and the controller stops the sewing machine in response to the cessation signal. The controller further recommences the sewing machine in accordance with the arrangement data of the stitch patterns and the stitch pattern data for the next stitch pattern. Since the uncompleted stitch pattern is not formed again after the cause of the accident is removed, the sewing machine can effectively form stitch patterns, especially when repeatedly forming a single stitch pattern or a single combination of stitch patterns.
