WEBBING FILMS WITHOUT A RELEASE LINER
The following are the basic webbing procedures for
webbing films without a release liner:
1. Select films slightly wider than the image to allow for a
border without film waste. A border of 1/8 in. to ¼
in. (3 - 6 mm) is adequate.
2. 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.
3. Once the laminator reaches correct operating
temperature, stop the laminator and raise the top
roller.
4. 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!
5. 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.
6. Pivot the front table down for easier webbing access.
7. BOTTOM FILM: Pull the film up from the bottom
unwind shaft, behind the bottom center idler and
place it evenly over the top film draped over the face
of the top roller.
8. The two films will then heat and stick together.
9. Set the Shim Wheels to 1/16 in. (2mm) to allow for
the thickness of the leader-board.
10. Use a leader-board to push the film(s) through the
main roller nip.
11. Lower the top roller and pivot the in-feed table into
position.
12. Moving to the rear of the laminator, use the foot
switch to advance the leader board.
13. 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.
14. Raise the top pull roller and advance the leader board
through the pull rollers.
15. 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).
16. Return to the front of the laminator and set the front
Shim Wheels to -1/16 in. (-2 mm).
17. 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!
