3-5 Unwind Brakes
Tighten the unwind brake so that it applies sufficient tension to laminate. Turning the knurled collar in
a clockwise direction increases the unwind tension applied to the laminate. Turning the collar counter-
clockwise decreases the tension. The best setting for the brake tension is determined by the materials
you are using and is learned through experience.
Note: In general, no or light unwind tensions will be required.
