The following are the basic webbing procedures for
webbing films with 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.
•
Once the laminator reaches 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!
•
TOP FILM: (film with a release liner) Pull the film
down from the top unwind shaft, and place it evenly
over the face of the top roller.
•
RELEASE LINER: Place a spare core over the front
top wind-up idler. Separate the film from the release
liner. Attach the release liner to the spare core using a
piece of tape.
•
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 stick together.
•
Set the Nip Setting to 1/16” (2mm) to allow for the
thickness of a leader-board.
•
FILMS INTO NIP: Use the leader-board to push the
film(s) into the main roller nip.
•
Lower the top roller and use the foot switch to
advance the leader board through the nip.
•
NOTE: Keep the film under tension (holding back
on the film roll) to prevent the photoelectric eyes
being tripped.
•
When the film reaches the chill shoe, cut off the
leader board.
WARNING! Do not use open blades to cut or
slice on the surface of the chill shoe. Small cuts
and scratches will affect the output quality.
•
Using the footswitch, feed the film into the pull
rollers.
•
Check at the rear of the laminator, making sure the
film does not wrap around the enclosed pull rollers.
•
Raise the top roller and set the Nip Setting to ‘0’, then
lower the roller again.
•
Return the in-feed table to its working position.
•
Apply 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.
