IMPORTANT! Ensure that the Shim Wheel
settings of the rollers correspond to the board
thickness.
OPTIONAL: Adding a heat-activated laminate to
the backside of the board will prevent the board
from warping over an extended period of time.
WEBBING PROCEDURE
• Load the roll of pressure sensitive adhesive with the
exposed adhesive facing you. Do not wrap around
the top idler.
• Use a leader-board of the same thickness as the
boards to be coated.
• 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.
