3.1 Pre-Shrinking of Felt Blanket
If you need to replace your felt blanket then the new part should be pre-
stabilized to resist high temperatures.
Please perform the following procedures:
1. Ensure the actuator is located at the centre position as shown
in image No.1.
2. Remove No.3 and No.4 relays to disconnect the felt blanket
auto-aligning system.
3. To keep the blanket under the correct tension status a
pressure reading on the pressure regulator should be 0.2. You
should then turn the ‘felt tension/release’ crank handle to its
maximum and then turn back by half a turn.
4. The procedures for pre-shrinking the felt blanket should be
based on the following table:
Temperature Working time
120°C 248°F 3 hours
140°C 284°F 3 hours
170°C 338°F 4 hours
200°C 392°F 4 hours (very important)
230°C
446°F 4 hours
N.B. During the pre-shrink period adjust the tracking of the felt
blanket manually or reverse the rotation direction of the felt.
After the pre-shrink period is completed the machine should be run
for 6 hours at 220°C (428°F),
then the No.3 and No.4 relays should be
replaced to activate the auto aligning system. The white sensor rods on
either side of the felt blanket should then be closed to touch the edge of
the felt blanket.
