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.

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.
