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” (3-6mm) 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).
WARNING! The rollers should be down 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.
• 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!
• TOP FILM: Pull the film down from the top
unwind shaft, behind the top center idler and place
it evenly over the face of the top roller.
• BOTTOM FILM: Pull the film up from the bottom
unwind shaft, behind the front bottom idler 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 Shim Wheels to 1/16” (2mm) to allow for
the thickness of the leader-board.
• Use a leader-board to push the film(s) through the
main roller nip.
• Lower the top roller and pivot the in-feed table into
position.
Moving to the rear of the laminator, use the foot switch
to advance the leader board.
• Feed the leader-board over the first chill idler and
under the second chill idler.
NOTE: For top and bottom film combinations
of 10 mil or less, feed over the first idler and
under the second. For film combinations of 10
mil or over, feed over both chill idlers.
• Raise the top pull roller and advance the leader
board through the pull rollers.
• Holding the leader board up against the top edge of
the top pull roller lower the roller. Make sure the
rear Shim Wheels are set to ‘0’ (0mm).
• Return to the front of the laminator and set the
front Shim Wheels to ‘-1/16’ (-2mm).
• Using the footswitch advance the films, applying
light unwind brake tension gradually on both
unwind shafts until there are no wrinkles in the film
as it goes into the nip.
You are now ready to feed images!
