Buttonholes on cassette
Buttonholes on cassette
In addition to the ordinary buttonhole on the control
panel, there are five more types of buttonholes on cas­
sette. The upper two are sewn with the same type of
columns as the ordinary buttonhole but with rounded
bar tacks, either at both ends or just at one end. Both
t5T3es may be used in light and medium fabrics. Note that
the bar tack is extended to a certain degree and the
buttonhole must therefore be slightly longer than the
diameter of the button.
The buttonhole in the middle has columns sewn with
reinforced zig-zag, producing a more pronounced
buttonhole that is suitable for coarser fabrics.
These three buttonholes are sewn in the normal way as
described for ordinary buttonholes and can also be auto­
matically repeated. See page 29.
The keyhole buttonholes, used in tailoring, are sewn
completely rounded at one end. One of them is finished
with a straight bar tack while the other has a tapered bar
tack.
When sewing a keyhole buttonhole it should be placed
in such a way that the button conceals the rounded end.
This means that you must sew the buttonhole on the
garment, with the front edge away from you. Note here
that the rounded part is extended, so to start sewing the
rounded end, press the reverse feed button H allow­
ing sufficient space for this part of the buttonhole to be
formed.
