Weft length adjustment
The diameter of the Weft Feeder Spool Body must be set according to the indication
shown
on the loom Dialog panel
display.
Proceed as follows
:
1.
Loosen the screw
B
and raise the Photocells/Electromagnet Group. Fix it.
2.
Loosen the both
C
socket head screws (3 mm socket).
3.
Turn the Winding Disc until the eyelet is in the upper position.
4.
Loosen the
D1
socket
head screw (3 mm socket).
5.
Turn the Winding Disc until the eyelet is in the lower position.
6.
Loosen the
D2
socket head screw (3 mm socket)
7.
Adjust the diameter of the Spool Body by turning the
E socket screw (5 mm
socket screw
with the hole for D1 screw)
in order to move the sectors of the
Winding Group to the
requested reference according to weft length to be
inserted (see page 10).
8.
Turn the Winding Disc until the eyelet is in the lower position.
9.
Tighten the
D1 and D2
socket head screws (3 mm socket) to block the fixed
sectors
(remember to center the hole on the screw head,
points 3 and 5).
10.
Check that the movable sectors are centrally positioned in respect with the fixed
ones.
11.
Tighten the two screws
C
to block the movable sectors.
12.
Turn the Winding Disc and check that no movable sectors get in contact with
the fixed
ones; this is in order to avoid possible damages when the feeders is in
operation. If the
sectors get in contact, use the
C
screws to
adjust the movable
sectors.
13.
Loosen the screw
B
and position the
Photocells/Electromag
net
gro
up
so that the
distance
between the Electromagnet and the
Spool Body i
s about 1
-
1.2 mm (see

-
use the special gauge supplied
with the
feeder).
14.
Load the reserve as described on page 18.
15.
Start up the loom and check if the length weft
is as required. If it is too long, decrease a bit
the spool body diameter. If it is too short,
increase a bit the diameter.
Note:
Fixing torque
recommended for the
screws
D1, D2
and
C
= 2.3 Nm ± 10%
