5.3.4 Presetting the tension
To enable the film to unwind without wrinkles a momentum (brake or 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 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 5.1.3).
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 to unwind 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 and the leader panel is out of the nip.
During processing the pressure can be adjusted. The best pressure setting for thin films is
about 80%.
Panels
When processing panels, the leader panel is used to preset the pressure.
Use a leader panel of the same material, thickness and width as the panels to process.
1.
Set the nip to the thickness of the panel.
2.
Feed the panel into the nip in slow mode.
3.
Set the pressure to approximately 80% for full-width panels.
CAUTION:
For narrower panels set the pressure proportional to the width between 40%
and 80%. E.g. half width equals 60%.
4.
Push the start button to run the panel through the machine.
