WEBBING FILMS WITHOUT A RELEASE LINER
The following are the basic webbing procedures for
webbing films without a release liner:
•Select films slightly wider than the image to allow
for a border without film waste. A border of 1/8”
to 1/4” (3-6 mm) is adequate.
•Ensure the main roller’s temperatures are set
according to the recommendations of the laminates
being used (see literature enclosed in your material
box). Refer to the process guide on the front of the
laminator.
WARNING! The rollers should be together and
turning while heating up to provide even heat
distribution and prevent roller flat spots from
developing.
•Once the laminator reaches correct operating
temperature, stop the laminator and raise the top
roller.
•Pivot the front table down for easier webbing
access.
•Load and center the films on top and bottom
unwind shafts with the dull adhesive side facing out
and the unwind brake tension released.
NOTE: Check if the film widths of the lower
and upper web are the same!
•Remove the image guide, the in-feed table and the
wind-up idler.
•TOP FILM: Pull the film down from the top
unwind shaft, and place it evenly over the face of
the top roller.
•BOTTOM FILM: Pull the film up from the bottom
unwind shaft and place it evenly over the top film
draped over the face of the top roller.
•The two films will then heat and stick together.
•Set the Nip-knob to 1/16” (2mm) to allow for the
thickness of a leader-board.
•FILMS INTO NIP: Use the provided leader-board
to push the film(s) through the nip.
•Lower the top roller and place the in-feed table into
position.
NOTE: Keep the film under tension (holding
back on the top unwind shaft, not the film roll)
to prevent the photo-electric eyes being tripped.
•Using the footswitch, advance the leader-board
between the pull rollers until the end comes out
through the pull rollers.
•Release the foot switch and set the Nip-knob to ‘0’,
(0 mm).
•Moving to the rear of the laminator, with the film
and leader-board hanging out of the laminator, cut
off the leader-board.
•Return to the front of the laminator and run the
laminator, applying light unwind brake tension
gradually on both unwind shafts until there are no
wrinkles in the film as it goes into the nip.
•Run the laminator for about 3 feet (1 meter), to
work out any wrinkles. If wrinkles persist, cut the
film and web the laminator again.
NOTE: Best results will be obtained when the
film unwind tension is zero or very light.
Wrinkles, visible on the roller face do not show
on the output.
•Refit the image guide on the in-feed table.
