Adapting
the
buttonhole
length
3
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
and
dual
feed.
If
the
buttonhole
seams
do not
coincide,
press
‘tie-off/buttonhole”
key
19
to
switch
from
fully
automatic
to semi-automatic
during
sewing;
one
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).
