1. PULL ROLL CLUTCH PRESSURE
GAUGE - Measures and displays the air
pressure driving the pull roll clutch, which sets
web tension.
2. PULL ROLL CLUTCH AIR PRESSURE
ADJUSTMENT - Adjusts the clutch pressure
from zero to maximum as the control is turned
clockwise.
3. PULL ROLL AIR PRESSURE GAUGE -
Measures and displays the air pressure pushing
the pull roll down.
4. PULL ROLL AIR PRESSURE
ADJUSTMENT- Varies the air pressure fed to
the cylinders that drive the pull roll down.

Setup of the ORCA-III Laminator is quick and
straightforward when instructions are followed
exactly.
CAUTION
Always use the same shim settings on the left
and right side of the laminator.
To adjust the nip please see Section 4: Maintenance
and Troubleshooting.

Use only the minimum amount of roll pressure
needed to accomplish the task. While higher pressure
can make the adhesive bond faster, excess pressure
can damage the rolls. Wrinkles and bubbles have
causes that generally cannot be cured by applying
more pressure.
CAUTION
Excess pressure can damage the laminating
rolls. Minimum laminator roll pressure is
consistent with good results.
A typical roll pressure for soft substrates such as
Foamcore or Orca-Board is between 20 to 30 pounds
per square inch (PSI) or 140 to 205 kPa.
The range of typical values for hard substrates is 25
to 50 PSI or 170 to 345 kPa.
