3. SETTING UP THE DISTANCE BETWEEN CLAMPING FEET
Change the distance between clamping feet Ê if you want to change workpiece or number of
buttonholes to be sewn.
3.1. Take out screws Ë of the right holder Ì
and adjust the required distance X between
the Indexer clamping feet Ê and clamping
mats Í of the sewing head feet.
3.1.1. The minimal distance X can be found
in display pre-set parameters.
Example:
You wish to sew 4 buttonholes with the distance of 25 mm between them. The total length is 75 mm
(the first buttonhole is always sewn in indexer home position).
X = (number of buttonholes -1 fixed in
place) x distance between them + 2 mm
(minimal play between Indexer feet and
clamping mat of the sewing head; see
chapter 2).
X = (4-1) x 25 +2 = 77 mm
Minimal distance must be adjusted
to 77 mm.
If the minimal distance is shorter, the
display signals an error message – the
required operation cannot be performed.
3.2. Secure the correct position by screws.
Do not forget to adjust the play between a
clamping foot and desktop ( see chapter 1).
3.3. Check the setting by pressing the
button
. The device must move freely
without stopping.
Note: Setting up the distance between
clamping feet needs to be done always by
changing the position of the right clamping
foot of the Indexer only!
