Meaning
This parameter changes the
intermediate-fabric type.
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.
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.
In round tacks and eyelets the overlap can be
adjusted.
In round tack buttonholes, the number of
stitches in the round tack. 4, 6, 8 or 10 stitches
are possible.
This parameter changes the throw width in the
cross tack.
In buttonholes with cross tacks, the overall
length of the cross tack (measurement qb).
In buttonholes with cross tacks, the gap
between stitches in the cross tack
(measurement qs).
In buttonholes with cross tacks, the position of
the cross tack with respect to the
centre(measurement ql).
- = cross tack left
+ = cross tack right
In buttonholes with cross tacks the distance
between the buttonhole side and the cross tack
can be set.
The diameter of the eyelet (measurement d).
The number of stitches in the eyelet.
