Abstract
A zigzag sewing machine comprises a pattern data memory, a fixing stitch memory, a read-out unit, a controller, a determination unit, a switch-over mechanism and a stitch forming mechanism. The read-out unit reads out pattern stitch data from the pattern data memory means. Based on the read-out stich pattern data, the controller controls the stitch forming mechanism to form a pattern on a fabric. If a repeat sewing mode is selected, the controller repeatedly sews the pattern. Meanwhile, the determination unit determines if a given pattern whose sewing is in progress is a predetermined last pattern or a pattern which was not initially designated as a last pattern but was later redesignated as a last pattern by mode switching. If the determination unit determines that the pattern whose sewing is in progress is the last pattern, the switch-over mechanism stops the read-out unit from reading out further pattern stitch data and switches over the read-out unit to the fixing stitch read-out mode after the sewing of the last pattern is completed. Then, based on the result of the determination, the controller drives the stitch forming mechanism to form fixing stitches after the last pattern is sewn.
