UNWIND BRAKE / COOLING SYSTEM OPERATION

SETTING THE UNWIND BRAKE TENSION

*Refer to the Features Page for identification.

IMPORTANT: The brake tension greatly

affects the smooth flow of the laminating film.

• Adjust the unwind brake so that it applies sufficient

tension to the laminate.

• Turning the unwind brake in a counter-clockwise

direction increases the braking tension applied on

the laminate.

• Turning the unwind

brake in a clockwise

direction decreases

the braking tension.

• The best setting for

the unwind brake

tension is

determined by the

materials you are

using and is learned through experience.

COOLING SYSTEM

• The Image

6500 has a dual position cooling tube,

which can be placed above or below the center chill

idlers to cool heat-activated materials.

• While the majority of the time the cooling fan tube

will be used in the position below the chill idlers, it

can be used in the position above the chill idlers to

assist with cooling down the top main roller. Pivot

the airflow holes towards the top main roller.

Figure 17: Inserting Cooling Tube

To remove the cooling tube from the bottom

location:

• Grasp the cooling tube with fingers or you can use

your fingers in the airflow holes to lift the closed

end of the cooling tube out of the bracket.

• Lift upwards at an angle, pulling the opposite open

tube end out of the cabinet opening.

• Lower the open end at an angle until you can clear

the upper bracket with the opposite end.

• Pull the tube up through the center of the chill

idlers.

To insert the cooling tube in the top location:

• Insert the open tube end at an angle into the cabinet

opening.

• Lower the closed tube end to place it in the bracket.

• Reverse the above procedures to change from the

top location to the bottom location.

• 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.
