6.0 ADJUSTMENTS
6.2 Film Tension Adjustment
The film should be taut. The film roll should not be difficult to turn by hand. The tension should
provide a slight drag as the film shaft rotates. Too little tension will cause wrinkles, too much
tension will cause stretching and excessive noise as the film passes over the heat shoe . Uneven
tension between the top and bottom rolls will cause curling. More tension on the upper roll will
cause the film to curl upward. More tension on the lower roll will cause the film to curl
downward.
To adjust bottom brake:
1. Push and hold the brake lever, (Figure 1), located on the left side frame by the film roll. Rotate
the film roll until the lever engages the mechanism.
2. While holding the lever in place, rotate film roll clockwise to increase film tension or
counter clockwise to decrease film tension.
3. Release the lever and check brake tension by rotating the roll of film. Resistance should be
slight, not excessive.
4. To adjust top brake repeat steps 1 through 3.
5. Laminate test samples and increase or decrease brake tension as necessary.

6.3 Roller Pressure Adjustment
Pull roller (rear) and nip roller (front) tension should be equal on the left and right sides. To
adjust the front roller pressure, measure 5/32" from the top of the nut to the top of the roller
adjustment bolt.To adjust rear roller pressure, measure 1/8" from the top of the nut to the top of
the roller pressure adjustment bolt. The roller pressure is set at the factory and should not need
adjustment .
