5.2.3 Loading the unwind shaft into a machine
•
Set interlock bracket to up position and align right shaft holder as
shown in figure 15.
•
Firmly grasp unwind shaft placing hands up against the ends of
film roll to keep the film from sliding on the shaft while loading.
•
Place the shaft, including the material, into the laminator by
inserting it onto the right unwind shaft holder.
•
Press against the spring pressure, until you can place the other
end of the shaft onto the left unwind shaft holder.
•
Move the interlock bracket is to the down position (figure 12).
•
Center the material roll in the laminator.
5.3 Webbing the films
The machine must be webbed before laminating images. The machine can be webbed for single
sided or double sided processing. When mounting images, the machine is not webbed.
Note: In single sided processes adhesive residues will stay behind on the bottom roller when the
film is wider than the images. To prevent this, a release liner of the same width as the top film can
be used in the bottom section. The release liner can easily be removed later on. Or use a film of
the same width as the image.
When processing panels, a leader panel (waste panel equal to the panel to be processed) is needed
to feed in the film.
5.3.1 Preset the tension
To enable the film to unwind without wrinkles tension (brake) can be set.
On the right-hand (control panel) side of the machine you will find a tension control ring on each shaft.
Turn the tension control ring counter-clockwise (top to rear) to set the tension or clockwise (top to
front) to release the tension.
When the film is webbed, it is recommended to set a low tension to each shaft by turning the ring
counter-clockwise until you feel some resistance. The film should be tight, but able to be pulled by
hand without too much effort
Too much unwind tension can lead to stress in the material and even cause wrinkling of the laminate.
A properly set up machine should run film wrinkle free with minimum brake tension.
