J prog - (1) •'-_-o 0 & L \- Linen buttonholes (fully automatic> prog - - L 18 -3+ J 5 A _ Sewing thread: Embroidery and darning thread Generally buttonholes are sewn onto double material. In spite of this, a piece of paper should be placed underneath during sewing. First draw the spacings and the distance from the edge. This point always marks the beginning of sewing. Ten buttonhole lengths are stored in the compu ter, from 7,0 to 16 mm. On program selection a programmed buttonhole length of 14 mm and a buttonhole width of 4 mm appear in the display. Select the length of the but tonhole using stitch-length keys 7 (Fig. 1). The machine will automatically sew the selected but tonhole. Before beginning the buttonhole pull the runner of the buttonhole foot fully to the front. For the following buttonholes it is best to lift the fabric a little in order not to affect feeding. The sewing speed should always be the same. Correcting a buttonhole If a buttonhole does not turn out well, cancel it by pressing "pattern start" key 26 and sew it again. Changing the buttonhole width For every type of fabric, the corresponding but tonhole width can be determined up to 5,5 mm. For heavy materials select a wide buttonhole 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. 5).A buttonhole width of 4 mm is stored. 78 Adapting the buttonhole seam lengths with the balance keys With "balance" keys 5 the left buttonhole sean length can be adapted to the right one. Sew a sample buttonhole first. Example: If the left seam is too short (Fig. 4a) Select balance +1 to +3 with key, or more i required. If the left seam is too long (Fig. 4b) Select balance -1 to -2 with key, or more i required. • Sew the first buttonhole seam at the require length and • the first bartack. • Press balance keys 5, "+" or"-", and adjust thi second buttonhole seam length to the first oni (Figs. 4a, 4b). • Sew last bartack. The change made in this way will be main tamed for the following buttonholes.
