Now. only the left upper segment of the buttonhole symbol is flashing (Fig. 3). The machine then automatically sews the first bartack and the return seam (Fig. 2b). Shortly before the end of the seam the machine sews slowly, stitch by stitch, in order to draw attention to the last bartack One zigzag stitch before the end of the first buttonhole seam. • Press key 19 again The second bartack is now sewn and tied off (Fig 2c). (Both segments of the buttonhole symbol are off, Fig. 4). Now the bLittonhole is stored Without having to actuate further keys all following button holes can be sewn automatically. Adjusting the density of buttonhole seams With stitchenglh keys 7 the buttonhole seame can be set more densely or loosely. The stored buttonhole density is 0.5 mm Make a sample buttonhole first Changing the buttonhole width For every type of fabric, the corresponding but tonhole width can be determined up to 55 mm For heavy materials select a wide buttonhote and for light materials a narrow one. With stitch width keys 8, you determine the required buttonhole width The length of the cut changes automati cally (Fig. 6). A buttonhole width of 4.5 mm is stored. Adapting the density of the left buttonhole seam to the right E one With "hatance" keys 5 the left buttonhole seam can be adapted to the right one • Sew the first buttonhole seam at the required length and the first bartack. • Press 'balance" keys 5, "+" or "-", and adapt - the second buttonhole seam to the first one (Fig. 5). • Press "pattern start" key 26. Afterwards program the buttonhole as described on this page. Make a sample buttonhole before you sew buttonholes on a garment Note: If the buttnnhole seams of the stored but- fonhole do not coincide, make another correction at "balance" keys 5 Adapting the seam lengths or stored button holes with the baTance keys, see page 80. Adapting the buttonhole 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 foot No. 1 A R and dual feed. If the buttonhole seams do not coincide, press R "tie-off/buttonhole" key 19 to switch from fully automatic to semi-automatic during sewing, one R segment flashes (Fig 3) and you can determine your own second bartack When key 19 is pressed again the buttonhole pro grammed before is sewn fully automatically and the segment does not flash anymore After sewing, cut the buttonholes open (see page 94). 82 8
