Note: When both upper and lower section are used, place both films at exactly the same
position.
Make sure the films (and scrap cores) are set up and aligned properly.

5.3.4 Use of a splitter bar
The splitter bar has two functions:
1.
•
When processing film with release liner, it is used to split the release liner from the film.
•
When processing heat sensitive film it is used to reroute the film to increase the contact surface
with the heated roller.
Figure 16: Use of a splitter bar.
Film with release liner (A) is running via the splitter bar where the release liner is split off. Pressure
sensitive film without release liner (B) would leave adhesive remains behind on the splitter bar, so
this is lead over the splitter barHeat activated film (C) needs as much contact surface with the
heated roller as possible. Therefore this film is lead underneath (via) the splitter bar.
5.3.5 Presetting the tension
To enable the film to unwind without wrinkles tension (brake) can be set to the roll. On the right-
hand side of the machine you will find tension control knobs, corresponding with each shaft.
Turn the tension control knob clockwise to set the tension or counter clockwise to release the
tension.
Note: The unwind/wind-up shafts in the bottom half have a split tension setting: Turn clockwise
for unwind tension and counter clockwise to release the unwind tension. Turning further counter
clockwise will set wind-up tension (see also section 5.1.3).
When the film is webbed, it is recommended to set a low tension to each shaft by turning the knob
clockwise until you feel some resistance. On the unwind shaft this will prevent film from unwinding
without tension. On the motor-driven wind-up shaft it allows the shaft to slip and adapt its rotation
speed to the speed of the film.
5.3.6 Pressure setting
Thin images
When processing thin images (printer output, posters, etc.) pressure is preset when the upper and
lower material is webbed. When the leader panel or release board is through the nip, the nip is set
to zero and pressure is preset.
The best pressure setting for thin films is about 80%.
During processing the pressure can be adjusted.
Panels
When processing panels, a leader panel is used to web the film(s). This leader panel is at the same
time used to preset the pressure.
Use a leader panel of the same material, thickness and width as the panels to process.
Set the nip to the thickness of the panel.
1.
Feed the leader panel into the nip in slow mode.
