If the top main roll or top pull roll move up or down
unevenly, the air cylinder flow controls need to be
adjusted (see Figure 4-5).
To adjust the air cylinder rate for the main rolls:
1. Make sure there is both air and power to the
machine.
2. Remove both cabinet covers.
3. Loosen the large knurled locking rings.
4. Turn the main roll air cylinder adjustment valve
knobs on both sides to their fully in position and
mark them with a permanent marker to provide an
indicator. Do not jam shut; finger tight is sufficient.
5. Rotate the upper main air cylinder adjustment
knobs out 5 turns. Rotate the lower main air cylin-
der adjustment knobs out 3 turns.
6. The upper knob adjusts the up rate of the roll and
the lower knob adjusts the down rate of the roll.
Turn clockwise to reduce the rate of travel and
counterclockwise to increase the rate of travel.
7. Lower and raise the roll. The roll should fall and
rise evenly. If not, adjust the appropriate knobs
until the rates are even.
8. Lock settings in place by tightening the large
knurled locking rings.
9. Replace the cabinet covers if no further adjust-
ments are needed.
To adjust the air cylinder rate for the pull rolls:
The adjustment procedure for the pull rolls is similar to
the adjustment procedure for the main rolls.
1. Make sure there is both air and power to the
machine.
2. If necessary, remove both cabinet covers.
3. Loosen the large knurled locking rings.
4. Turn the pull roll air cylinder adjustment valve
knobs on both sides to their fully in position and
mark them with a permanent marker to provide an
indicator. Do not jam shut, finger tight is sufficient.
5. Rotate the pull roll air cylinder adjustment knobs
out 3 turns. Rotate the lower pull roll cylinder
adjustment knobs out 2 turns.
6. As with the main rolls, the pull roll should rise and
fall evenly. If it does not, adjust accordingly.
7. Lock settings in place by tightening the large
knurled locking rings.
8. Replace the cabinet covers if no further adjust-
ments are needed.
