Web Tension Bottom: Medium
Chill Idlers: Over both
Shim Wheel Settings: Substrate Dependent
NOTE: Ensure that the Shim Wheel settings of the
rollers correspond to the board thickness.
NOTE: 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. Then stop the
motor and raise the top roller.
