PRE-COATING BOARDS
This process is used to coat substrates with a self-
adhesive coating onto which images can be mounted.
Preparation:
IMPORTANT! Ensure that the Shim Wheel settings of
the rollers correspond to the board thickness.
• Load the roll of pressure-sensitive adhesive onto the top
unwind shaft of the laminator with the exposed adhesive
facing you.
• 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 and choose
a speed setting.
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.
