OPERATION OF THE ROLL BENDER
The roll bender machine is designed to initially pinch/grip the sheet material to be formed between the
upper roll (not adjustable) and the lower roll (adjustable upward or downward manually by means of
adjusting screws located in the housings at each end of the lower roll).
The rear (bending) roll is adjustable by means of adjusting screws located in the housings at either end of
the rear roll.
Adjustment upward or downward, on an inclined plane, moves the bending roll toward or away from the
material passing through the pinch (upper and lower) rolls, thus controlling the radius of the cylinder being
formed.
Longitudinal grooves in the rear roll will assist in starting the curvature of the material up and over the rear
roll.
Rear roll position indicators are located at each end of the roll to enable the operator to maintain parallel.
Note: The markings on the indicators are reference marks only and do not indicate any specific radius,
diameter, measurement, etc. and are to be used only as an aide in determining additional adjustments
from a previous position.
Cylinders are formed by inserting the sheet between the gripping rolls as shown in the above illustration.
