5.4 Webbing
For most processes the machine must be webbed before images on thin film or on panels
can be processed. The machine can be webbed for single sided or double sided
processing.
Note:
In single sided processes, adhesive residues will stay behind on the bottom roller where
the film is wider than the images. To prevent this, a release liner or craft paper of the
same width as the top film can be used in the bottom section. The release liner or craft
paper can be removed later on.
When webbing a film with a release liner, the film is always fed over a splitter bar (or idler),
where the release liner is separated from the film.
To increase contact surface with the heated main roller, heat sensitive film also runs via
this idler (splitter bar).
In this section an unwind (or wind-up) roll can also be an unwind/wind-up shaft position set
as unwind (or wind-up).
To feed films through the machine, a leader panel of the same thickness as the panels to
laminated may be used. A thin leader panel can be used when laminating images. When
this panel is through, the nip is set to zero and the images can be fed.
5.4.1 Upper section only
a.
Remove the image guide.
b.
Unwind the film from the upper or top unwind roll.
•
Feed a pressure sensitive film (without release liner) from the top unwind roll over
the splitter bar.
•
Feed all other films underneath the splitter bar.
c.
Pull the film forward until approximately 10 cm (4 in.) lays on the in-feed table.
If the film has a release liner:
•
Peel off the release liner.
•
Pull the release liner up and stick it to the scrap core on the wind-up shaft.
d.
Stick the leader panel to the film.
e.
Feed the panel into the nip using slow mode.
f.
Refit the image guide.
g.
Stick the front end of the image to the leader panel or butt up the next panel.
During processing:
Check and adjust the tension on the unwind- and wind-up shafts.
Check and adjust the pressure setting while feeding through the leader board and
images.
Now speed can be set to normal.
5.4.2 Upper and lower section
A leader panel is needed of the same thickness as the images or panels to process.
For thin images use a thin leader panel and set the nip to zero after the panel is through
the nip.
