Plate rolling machine
3 Roll fixed axis plate bending machine – Model 2520
Available in width of 2000,2500,3100,3600 & 4100 mm.
Capacity in thickness 12, 16, 20, 25 & 30 mm.
Infinitely variable speed of rolling as per requirement.
Faster rolling for smaller thickness.

2. Main Unique Features of ‘Roll Master’ make plate bending machines
1. Control Panel :
The control panel is user friendly & most
convenient to operate.
All functions like, bending cyl movement, cone
guide, drop-end, hold & roller rotation start/stop is
on panel. Operator can see bending cylinder
position as digital display on panel.
2. Drop end :
Most convenient & easy way to
remove rolled shell from machine
due to more clearance between
bottom & top roll & higher degree
of inclination of top roll.
3. Cone guide:
Cone guide which is must for taper/conical
rolling is provided to be operated by push
button & is duly hardened to 55-60 R.C.
hardness with heavy duty bearing within & to
be operated from panel.
4. Section bending:
An extended shaft provided on both top &
bottom roller to facilitate die mounting
which enables bending of different
sections like, beams, channels, angles,
pipes, flats, round/sq bar bending. Capacity
up to size 200 channel & beam.
The operation is by push button on panel.
5. Greater tilting angle:
Greater tilting angle for taper shell
rolling with major dimensional
difference between small & large
diameter.

1. Operation Complete manual fully automatic by
operation cyl & button
2. Manpower required Min. 3 to 4 persons Only 1person require.
3. Cone bending manual adjustment By push button adjustment
4. Roundness correction Not possible Easily possible by
(Apple effect removal) push button
5. section bending Usually light structural up to Possible up to size
75×75 angle & 200 beam & channel
100×50 channel
6. Bottom roll support Bush of C. I. or P. B. material Heavy duty bearings
7. Profile More ovality apxly 5mm. Perfect roundness
within 1-2 mm.
8. Operation Time Slow due to Comparatively fast
manual work involve since fully automatic
9. Roller position To be decided by scale & Digital reading on meter
pointer hence not accurate for ease of parallalism.
10. Bending roller speed Constant Variable (more speed for less
thickness material.)
11. Bearing support Narrow bush hence less Extra wide bearing housing.
bearing area.
12. Maintenance cost More costly if P.B and G. M. Bearings less costly than
bush replacement needed. P.B. Or G.I. bush.
13. Down time Requires 2-3 day to change Machine can be restarted
bush after existing shaft size within 2-3 hours since
confirmation bearing replacement is faster.
14. lubrication To be done manually, Automatic lubrication hence
more wastage of oil guaranteed oiling to
bearings.

4. Standard Features
1. Hardened rolls up to 60 R. C.
2. Cone guide adjustable on button.
3. Section rolling arrangement.
4. digital display for pressure arm A & B
Optional features:
1. Soft rolls.
2. Frame mounted cone guide roller.
3. Fully ground, plated & polished rolls for S.S, copper or C. R. C. Rolling.
4. Inter changeable profile rolls with/without P.U. coating for thin & coated
metal rolling in profile Like G. I./color coated sheets.
5. Material feed table, vertical support for large dia. rolling & shell support.
6. Hardened section bending dies for angle , channel, beam, pipe etc.
7. Moving console for all around operator movement.
8. N.C. / C.N.C. control for mass production.
9. Infinitely Variable roller speed.
10. Automatic central lubrication system.

5. 4 Roll Plate Bending machine
This is a plate bending machine with 4 rollers & can perform Pre
Pinching & bending a plate in single pass.
This machine can roll more tighter diameter compared to 3 Roll plate
bending machine. Usually both top and bottom rollers are driven by G.B.
& motor but in some cases, top roller and 2 side rollers are driven one.
In this type of machine there are no sliding surfaces & the rolls move in
planetary motion for pre pinching of plate. This type of machine has
greater efficiency. Since there is no sliding friction & full power is
utilized for bending which otherwise approximately 30%. Power goes
waste in order to overcome friction loss in case of sliding surface guide
type bending machines.
The minimum diameter that can be rolled is approximately 1.1 times the
top roll diameter.
