THEORY OF OPER ATION
Warning: Possibility of crushing or pinching. 1) Do not insert limbs in the nip
area while rolls are rotating. 2) Do not lower the top r oll while limbs are in the nip
area.
Laminated samples can be prepared with or without heat. Single sample sheets to be
laminated are fed to the Nip from the Laminating Platforms to be laminated with material from
the Unwind Stand. The top Heat Laminating Roll can be controlled to pr ovide heat for heat
activated adhesive material. Laminating pressure is controlled by the Air Regulator. Speed and
direction of the laminating rolls is controlled by the control board. The travel speed of the top
Heat Laminating Roll is controlled by the four Exhaust Control Valves.
Each of the items mentioned above can be found in var ious sections of this manual with a detail
explanation of their function and method of operation.
POWER UP
Turn on the main power switch located on the front panel of the control cabinet. The display will
go through a power on self-test. It is also necessary to open the air supply valve.
Warning: Operating temperature for this equipment is 0 to 70 Celsius. The
equipment needs to be completely free of condensation, inside and out, before
applying power.
OPERATION
PRESSURE REGULATION
Turning the Pressure Regulator knob, located on the top of the control cabinet, controls the
pressure of the top roll at the nip. Turning the knob clockwise will increase the pressure and
turning it counter clockwise will decrease the air pressure. The Pressure Gauge, located on the
front of the control cabinet, will display the current air pressure on the top pressure roll.
FLOW CONTROL VALVES
The Flow Control Valves regulate the speed of the top pressure roll as it moves up and down.
Adjusting the valves in the following manner will regulate this movement. It may also be
necessary to adjust these valves to balance the movement of the air pistons in order for the top
Hot Roll Laminator Operating Instructions (HL-200/201)

pressure roll to travel evenly. If the speed of the two air pist ons is not equal, one side of the top
pressure roll will move faster than the other side.
Warning! Always operate with the top rolls downward motion at a slow speed.
The speed of the air pistons has been preset at the factory. These settings allow the top
pressure roll to move downward at a safe, slow speed, and move upwar d rapidly. If it becomes
necessary to adjust these valves, then use the following procedure.
• The bottom valve controls the down speed and the top valve controls the up speed.
• Turn the thumbscrews clockwise to go slower and counter clockwise to go faster.
• After each adjustment move the top pressure roll up by pressing the RED OPEN button
and down by pressing the GREEN CLOSE button at least one time to determine the
affect and need for further adjustment.
• Always maintain an even balance between the left and right Flow Control Valves to
avoid uneven movement of the top pressure roll when traveling up and down.
CONTROL PANEL OPER ATION
The HL-200/201 instrument allows the user to change speed and direction of the drive roll while
it is moving. The control panel has a circular menu system. See Table 1 for a listing of
selectable parameters.

EXHAUST CONTROL V ALVES
The motion of the top Heat Laminating Roll is controlled by the exhaust of air f r om each of the
two air cylinders. To regulated this exhaust there are 4 Exhaust Control Valves that are
adjusted at the factory before shipping. Follow the procedure below to adjust the speed and/or
even the motion of the top Heat Laminating Roll.
1. Set the Air Regulator between 40 and 60 PSI for the inlet air pressure.
2. Turn the Heat Power switch to off.
3. Cycle the top Heat Laminating Roll up and down wh ile not ing the speed and whether
one end of the roll travels faster than the other end.
4. First adjust for the even travel of the roll by choosing one direction of movement.
5. If you are adjusting the upward movement you will be adjusting the Exhaust Control
Valves mounted at the top of each of the Air Cylinders.
6. The adjustment is mostly a trial and error process. First adjust the valve on one cylinder,
by either turning the valve knob in for faster movement or out for slower movement, then
cycling the top Heat Laminating Roll to evaluate the movement.
7. Once you have the roll moving evenly in one direction, repeat the process for the
opposite direction by adjusting the opposed Exhaust Control Valves at the opposite end
of the Air Cylinders.
8. After adjusting the up and down movement of the top Heat Laminating Roll for even
movement, you can slow or speed up the movement in either direction by adjusting the
Exhaust Control Valves to release or retard the air flow exhaust accordingly.
