5.3.4 Presetting the tension
To enable the film to unwind without wrinkles, a brake tension 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 (combi) shafts 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 5.1.2).
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.
5.3.5 Pressure setting
Thin images
When processing thin images (thickness same as or less than the film) pressure is preset
when the upper and lower material is webbed.
During processing the pressure can be adjusted. The best pressure setting for thin films is
about 45%.
Panels
When processing panels, a leader panel is used to preset the pressure.
Use a leader panel of the same material, thickness and width as the panels to process.
a. Set the nip to the thickness of the panel.
b. Feed the panel into the nip in slow mode.
c. Set the pressure to approximately 40% for full-width panels.
CAUTION:
For narrower panels set the pressure proportional to the width between 20%
and 30%.
d. Push the reverse button to run the panel back through the machine.
