4. BUTTON SEWING ADJUSTMENT
Before the first sewing of any new button, the machine needs to be properly adjusted based on
the properties of this button and demanded sewing parameters. It is worthy to store this setting
in one of the button programs (refer to chapter D 2) so that it can be subsequently reused.
This chapter describes the sequence of button sewing adjustment: the initial operations are
described in chapter 4.1., adjustment of buttons with holes is then described in chapter 4.2.,
whereas shank buttons are described in chapter 4.3. Chapter 4.4. describes further sewing
adjustment for both buttons with holes and shank buttons.
4.1. PREPARING FOR FIRST SEWING
Once the machine is in Home Position (refer to chapter C 1) it
can be prepared for sewing. The procedure is the following:
4.1.1. Set the main sewing parameters:
a) Type of the button and stitching method you want to sew on
the Button Style screen.
b) Number of button attaching stitches by icons
on the
Button Parameters screen.
c) Neck height by icons
and number of neck wraps by
icons on the Neck Parameters screen. If the icon
appears on the same screen, the adjusted neck height is
not enough to perform neck wrapping due to a possible me-
chanical collision. Increase the neck height until
icon appears; later on, you can
again decrease the height in case you are able to extend the scope of wrapping in Y-direc-
tion using settings
and (refer to chapter C 4.2.).
d) Stitch style (show or blind stitches) by one of the icons
on the Stitch Style adjustment
screen.
e) Number of initial locking stitches by
and final locking stitches by on
the Locking Stitch adjustment screen.

first half of the button feeding phase - the button is brought
inside the button chuck. Now adjust vertical position of the
button chuck by icons
