4.3.5. Next phase is the neck wrapping phase, which is maintained from the Neck Parameters
screen. Pay attention to avoid collision with the shank eye for entire neck wrapping! First
select the shape of neck wrapping
or .Adjust the Y-position of the first wrap
using icons - “Neck Wrap 1/17” displayed in the Current sewing phase field (for
8 neck wraps as an example); avoid collision with the pucker-pin! If you use the op-
tion, check the position of the 2nd stitch (“Neck Wrap 2/17”) as well.
Normally, all neck wraps are sewn on the same position for shank buttons; if you like to
distribute the wraps across the neck, proceed to the last wrap (“Neck Wrap 17/17”) and
adjust the Y-position of the last wrap using icons
. You can use icons
to adjust the wrapping width - extending the width can help in avoiding collision with the
shank eye.
4.3.6. Finish the jogging till the last final locking (“End Lock”) stitch.
4.4. FURTHERSEWING ADJUSTMENT
You are now done with the basic sewing adjustment. Further sewing adjustments described in
this chapter help to obtain optimal sewing results according to your requirements.
Start by setting lower sewing speeds on the Sewing Speed Adjustment screen and low values
of thread tension on the Thread Tension Adjustment screen. You can try to sew the first button
and based on the result, adjust the following parameters:
4.4.1. Sewing tension shall be adjusted for individual sewing phases. Basically, small values
are recommended for initial locking stitches and show stitch
to avoid fabric
puckering, medium values for button attaching
, high values for neck wrapping
to get a firm neck, and similarly for final locking stitches .
4.4.2. Sewing speed is again adjustable in different sewing phases and is related to the
thread tension - the higher sewing speed results in higher tension. It is recommended to
set smaller speeds for potentially dangerous situations (e.g., sewing close to the button
or pucker-pin is adjusted).
4.4.3. For buttons with holes only, an unintended fabric puckering can be suppressed by
adjusting the button position during button attaching
- higher position means
looser button attaching threads and consequent reduced puckering.
4.4.4. By icons
you can optimally adjust the button position during neck wrapping
for both buttons with holes and shank buttons.
