Abstract (en)

A buttonholing sewing machine (1) in which a buttonholing sewing control is performed for formation of buttonholing seam. In performing a buttonholing sewing control, a control device (70) causes formation of a double buttonholing seam around a buttonhole and causes a knife mechanism (30) to form a buttonhole before formation of a second buttonholing seam and performs an opening width varying control of controlling a press mechanism (40) so that it makes the buttonhole opening width larger in forming the second buttonholing seam than in forming a first buttonholing seam. The thus-configured buttonholing sewing machine (1) can form a double buttonholing seam satisfactorily.
