Symbol Parameter Meaning
Intermediate fabric This parameter changes the
intermediate-fabric type.
Taper tack length In buttonholes with taper tacks, the length from the
tip of the taper to the end of the taper
(measurement kl). The minimum taper tack length
is 2 mm.
When changing the buttonhole length please
ensure that the maximum sewing length is not
exceeded. This can occur with taper-tack
buttonholes as the length of the taper tack forms
part of the sewing length.
When the buttonhole length is increased the taper
tack length is thus automatically adjusted
accordingly.
Taper tack overlap The distance between the two sides in the
straight section of the taper tack. When it is
0.0 mm one side is directly above the other.
Overlap In round tacks and eyelets the overlap can be
adjusted.
Number of stitches
in the round tack
In round tack buttonholes, the number of
stitches in the round tack. 4, 6, 8 or 10 stitches
are possible.
Throw width in the
cross tack
This parameter changes the throw width in the
cross tack.
Cross tack length In buttonholes with cross tacks, the overall
length of the cross tack (measurement qb).
Stitch distance in
the cross tack
In buttonholes with cross tacks, the gap
between stitches in the cross tack
(measurement qs).
Lateral cross tack
position
In buttonholes with cross tacks, the position of
the cross tack with respect to the
centre(measurement ql).
- = cross tack left
+ = cross tack right
Stitch count in the
eye
The number of stitches sewn by the machine in
the eye.
Stitch distance The distance between stitches within the side
of the buttonhole (measurement a).
The value must be between 0.5 and 2 mm.
Throw width in the
side
This parameter changes the throw width in the
side of the buttonhole.
