Abstract
In a buttonhole sewing machine, a sewing mechanism and a feed bracket are controlled to form a buttonhole defined by settings, such as zigzag stitch length, zigzag pitch, bar-tack length, bar-tack pitch, and cutter space. The buttonhole can be set on the operation panel and changed to various shapes by changing the above settings. In particular, the left and right zigzag stitch widths can be set differently, and the front and rear bar-tack lengths can be also set differently. Thus, the balance of the buttonhole can be finely adjusted.
