9.10 Sewing a buttonhole automatically
When the Buttonhole foot with slide No. 3A is used, the length of the buttonhole is measured automatically
by the lens on the presser foot. The buttonhole will be duplicated and the machine switches to the next step
automatically when the maximum length is reached. The Buttonhole foot with slide No. 3A is suitable for
buttonholes in the length of 4 – 31 mm, depending on the buttonhole type. The slide of the Buttonhole foot
must lie perfectly flat on the fabric so that the length can be measured accurately. All the programmed
buttonholes are the same length and of the same nice look.
