Control unit for controlling embroidery sewing machine

摘要

A control unit for controlling an embroidery sewing machine includes an embroidery-data storing portion, a feed-data extracting portion, and a thread-cutting-data adding portion. The embroidery-data storing portion stores embroidery data defining an embroidery pattern sewn by a sewing portion and a workpiece feeding portion. The embroidery data includes stitch data indicating needle drop positions for forming stitches on a workpiece and feed data indicating feed positions for feeding the workpiece. The feed-data extracting portion extracts the feed data from the embroidery data read from the embroidery-data storing portion. The thread-cutting-data adding portion adds thread cutting data immediately prior to the feed data extracted by the feed-data extracting portion. The thread cutting data instructs a thread cutting portion to perform thread cutting.
