a b Determining the bartack (semi-automatic) If you wish to determine the bartack in a pro grammed buttonhole, press "tie-off/buttonhole' key 19 (Fig. 5). A dash flashes in display 21 at the right side of program 92a, b, or c (Fig. 4). The machine now sews slowly just before the end of the second seam. When both seams are the same length, press key 19 again. The bartack is now sewn and tied off. If you wish to sew the next buttonhole fully auto matically, press key 19 again. (Sewing sequence as described on page 90). The flashing dash will then have disappeared. 8 Adapting the buttonhole seam length A garment may consist of different numbers of fabric plies, e.g. the buttonhole strip may consist of three plies and the collar stand of six - owing to the folded seam edge. In this case it is necessary to program the buttonhole for varying numbers of fabric plies in order to maintain the same button hole length as on the three-ply buttonhole strip. Note: For sewing buttonholes on knitted or very thin materials we recommend sewing toot No. I A and dual feed. Note: If you interrupt sewing at the reduced sewing speed by releasing the foot control, the machine will return to the normal speed when you start sewing again. When you are working in the bartack determining mode and have selected bartack design "a", you have to press the "tie-off/buttonhole" key when the second buttonhole seam has reached the second to last mark of the buttonhole foot. Obser vance of this always ensures correct finishing of the bartack. After sewing, cut the buttonholes open (see page 94) 91
