OPERATING PROCEDURE
1. Select forward rotation by depressing “Forward” button on control panel (see Fig. 6). White light will
be illuminated! NOTE: This only determines the direction of rotation the rolls will turn when rotation
is actuated by the footswitch. Always select direction of rotation when rolls are not rotating.
2. Insert the sheet material to be formed between the upper and lower rolls. Sheet material should
protrude through the upper and lower rolls until it is in contact with the rear (bending) roll. NOTE: The
amount of material from the gripping point between the upper and lower rolls to the contact point
with the rear roll will usually result in a flat area on the leading edge of the cylinder. To minimize this
flat area (see paragraph #6).
3. Adjust the lower roll upward to slightly pinch the sheet material, making sure the pressure is
approximately the same at both ends. Uneven pressure may cause the material to feed through at
an angle rather than straight through.
4. Adjust the rear (bending) roll upward until the material is curved upward forming an arc. NOTE: It is
advisable to use scrap material of the same gauge thickness as the intended cylinder to experiment
with until the proper cylinder diameter has been achieved. Several adjustments of the rear roll
position may be required to complete a cylinder of acceptable dimensions.
5. To initiate rotation of the rolls, depress the footswitch. (Amber light will be illuminated). This will
cause the material to be fed through the rolls. Before activating rotation be sure the sheet material is
aligned properly.
6. Preforming of the sheet material by inserting the leading edge of the material between the upper and
lower rolls (keep edge of material perpendicular to the rolls) then bending the sheet by hand upward
and slightly around the upper roll will greatly reduce the flat area mentioned in (paragraph #2).
(see Figure - 2).
7. To stop roll rotation, release the footswitch with an upward movement of the operators foot. A very
quick stop will occur, because the engaging brake (nearly simultaneously with the motor power being
switched off) will stop all rotating components. NOTE: For any Emergency Stop -- (roll forming
problem, parts of body or clothing become entangled in the rolls). The rotating rolls will immediately
stop, either from an upward movement at the footswitch - or depressing the “OFF” mushroom button
having a red light.
