UNWIND BRAKE / COOLING SYSTEM OPERATION
SETTING THE UNWIND BRAKE TENSION
NOTE: The brake tension greatly affects the smooth
flow of the laminating film.
Adjust the unwind brake (Figure 15, Item 2) so that it
applies sufficient tension to the laminate.
Figure 15: Unwind Brake
1. Turning the unwind brake in a counter-clockwise
direction increases the braking tension applied on the
laminate.
2. Turning the unwind brake in a clockwise direction
decreases the braking tension.
Generally, the least amount of tension produces the fewest
film wrinkles. The best setting for the unwind brake
tension is determined by the materials you are using and is
generally learned through experience.
COOLING SYSTEM
The Image 600 MD has a dual position cooling tube, which
can be placed above or below the center chill idlers to cool
heat-activated materials.
During most operations the cooling tube will be used in
the position below the chill idlers. However, it can also be
used in the position above the chill idlers to assist with
cooling down the top main roller. To improve cooling in
this configuration, pivot the airflow holes towards the top
main roller.
Figure 16: Inserting Cooling Tube
To remove the cooling tube from the bottom location:
1. Press the cooling tube towards the left cabinet,
compressing the spring to clear the cabinet opening.
2. Lift upwards at an angle and pull the tube up through
the center of the chill idlers.
To insert the cooling tube in the top location:
Reverse the above procedures to change from the top
location to the bottom location. Remember to replace the
magnetic tube opening cover over the lower cooling
opening.
The cooling tube can also be rotated to direct the airflow
as needed.
The majority of processes do not require the use of the
cooling tube, but for extensive running time, it is
recommended to use the cooling tube to cool off the chill
idlers quicker. Pivot the cooling tube airflow holes towards
the front idler, which receives the most heat from the
heated main roller.
Always web the film over the first idler to cool the
backside of the print first, thus preventing marks on the
hot front side of the print, which could affect the finished
appearance.
When using Mounting Adhesive on the back of images it is
best to run the film over both idlers. Running the film
under the second idler may cause the backing to separate
from the release liner.
