IIIOPERATION INSTRUCTIONS
1. HOW TO ROLL FORMING CIRCLE
1) Length of material –necessary to form the designed size circles is the 1st
consideration in circle forming. Decide approximate length of material need. Use
the formulary “C=πx ID”(C is Circumference;πis 3.1416; ID is Internal Diameter).
Sample:ID=200mm, operator need to prepare material length approximate
630.32mm or approximate length of material which need.
2) Cut a few pieces of material to the measured length for testing by roll forming. The
material might need to be lengthened or shortened depending upon the testing
result.
3) Loosen the clamping screws to the right position which operator can insert the
material between upper roll and bottom roller, then fasten the clamping screws to
ensure upper roller and bottom roller clamp in proper pressure.
4) Set the idle roller to same height of bottom roller.
5) Power on the foot switch to move the material between upper roller and bottom
roller forwardly to ensure the front-side material of measured length to pass through
the idle roller. (Drawing No.01)
6) Ensure the rear end-side material to reach between the upper roller and bottom
roller. (Drawing No.02)
7) Raise the idle roller bend forming the end-side material to designed angle to
complete the pre-bending at the rear end-side of measured length. (Drawing
No.03 &04).
8) Remove the material which has seen completed pre-bending at rear end-side to be
the expected diameter.
9) Repeat same step of No.3-7 (Drawing No.5-6) but pre-bend at the frontal end-side
material.

5
10) Down the idle roller as soon as the material has been pre-bend at the end side of
frontal and rear to be the expected diameter.(Drawing No.7)
11) Raise the idle roller step by step when the upper roller and bottom roller to form the
material to be circular between frontal and rear end-side.(Drawing No.8 & 9)
12) If the finished sample is not long enough or if the formed part is not the proper
diameter, additional samples will have to be made. Thousands of identical parts can
be precisely duplicated when proper adjustments of the roller have been made.
13) Get the correct modifying and forming after testing the few pieces to file your record
for official forming.
14) The same diameter as the diameter of the rolls and slightly larger can be formed.
To make the adjustment for the material thickness and to determine the material
length needed and the illustration given under above-mentioned step No.1～9.

3. ADJUSTING THE CLAMPING (BOTTOM) ROLLER & PINCHING(IDLE) ROLLER
1) The adjusting hand wheel mounted on the right-hand side frame of the machine
construction can adjust the bottom roller to clamp material tightly.
2) The hand wheel is mounted on right-hand side frame of machine construction
enable the operator to raise or lower the idle (pinch) roll, so the correct gap between
the upper and idle (pinch) rolls may be obtained to feed the designed stock into the
machine.
4. REMOVE THE FORMED MATERIAL
Lift clamp handle and slide the support lever handle to the right. The pinch roll will
rise. Slide the finished sample off the roll.
