Linen buttonhole, prog. 90,
programmable
Determining your own buttonhole length and
bartack
When
you press
right (+) program key (22) the
buttonhole symbol appears at the right side of
program 90 and both segments wilt flash (Fig. 1).
• Before beginning the buttonhole pull the run
ner of the buttonhole foot fully to the front.
• Sew the first buttonhole seam at the length
required (Fig 2a).
• Press tie-oft/buttonhole key 19 (Fig 2). 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.
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
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
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).
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

Note: If the buttnnhole seams of the stored but-
-
fonhole do not coincide, make another correction
at "balance" keys 5
