Application of the sewing components:
Sub-class 104VN—2 (Fig. 8)
Sub-class 104VN—2 S (Fig. 7)
The sewing components to be found on this machine are
designed for twin needle coarse stitch ornamental seams with
ofset stitch (small needle distance). Fig. 8.
Sub-class 104—102
The sewing components to be found on this machine are used
for beaded seams with or without cord insert (larger needle
distance) as well as the alternative of a single or triple needle
holder for single or triple needle seams. Single or triple needle
holder on request.
Sub-class 104-4102 S
The sewing components to be found on this machine fig. 7 are
designed for beaded seams without cord insert (smaller needle
distance). By changing the sewing components, the machine
can also be adjusted for sewing beaded seams without cord
insert with incision as well as for single needle coarse stitch
work.
For the given needle width, use also the needle holder which
corresponds to it (for this there are 3 size groups) and note the
following few points:
'fc
Bead seam (without use of scoring knife), fig. 3
Use the sewing components forming part of the machine.
When stitching narrow curves and points make sure to let the
left needle enter the same hole twice at lefthand corners and
to turn the material by 45° every time.
This instruction applies to righthand corners accordingly.
Bead seam (with use of scoring knife), fig. 4, on request, at
an extra charge.
Use the welting presser foot with scoring knife. The scoring
knife, which is merely clamped on, must be adjusted at a
height to fit the presser foot; the leather should merely be
scored but not cut through.
Adjust the scoring knife as follows:
Slacken the lateral knife holder screw. The knife is merely
clamped on. Adjust the height of the scoring knife. Tighten
the screw again.
