This process is used to coat substrates with a self-
adhesive coating onto which images can be mounted.
Images can then be mounted on the substrate. This
same process is used to create a sled.

REPARATION
:
IMPORTANT! Ensure that the Nip settings of the
rollers correspond to the board thickness.
•
If desired, set the top roller’s temperature to 120
°
F
(49
°
C). Using heat assist may improve the adhesive
bonding of the laminate.
•
The bottom roller temperature is OFF.
•
Load the roll of pressure sensitive adhesive onto the
top unwind shaft of the laminator with the exposed
adhesive facing out.
•
Use a leader-board of the same thickness as the
boards to be coated.
•
Pull the adhesive down from the top unwind shaft
and place evenly across the face of both rollers.
•
Press the foot switch and using the leader -board,
push the adhesive into the roller nip
•
Release the foot switch when the rear edge of the
leader-board is almost leaving the roller nip.
•
Position the board to be coated into the nip, behind
the leader board and choose a speed setting. Press
the motor switch ON or use the footswitch to
process the board.
NOTE: When coating boards, ensure that the next
board to be coated follows the previous board
without any gaps.
NOTE: Follow the last board being coated with the
leader-board again to allow the final board to clear
the laminating rollers and then stop the motor and
raise the top roller.
