ADJUSTMENTS
1. To increase the gap between SHAFT I (#17) and SHAFT II (#18) to allow for varying
thickness of materials, screw out the ADJUSTMENT KNOB (#24). To decrease the
gap, screw it in. Make sure to adjust both KNOBS an equal amount. See Figure 1.
2. To increase the gap between SHAFT I and SHAFT III (#8) to increase the diameter of
your rolls, screw out the ADJUSTMENT KNOB (#4). For smaller diameter rolls, screw
the KNOB in. For even rolls, adjust both KNOBS an equal amount. To create cones,
adjust one side more than the other. See Figure 2.
