ROUNDO was formed in 1964, and has since delivered almost 16 000
machines to satisfied customers around the globe. This has provided a
stability and continuity that is unique in our industry. ROUNDO
is currently represented throughout the world. ROUNDO machines
are world-renowned for outstanding performance,
reliability and quality.
ROUNDO has a team of over 75 dedicated full-time employees. They
are capable of shipping over 300 machines per year, of which 97%
are exported around the world. ROUNDO engineers and technicians
employ cutting-edge technologies and renowned Swedish technical
skills and know-how. The result is products that represent
quality, performance and reliability unique on the global

Angle Bending Rolls
ROUNDO offers the largest
selection of angle and section bending machines on the market with over 25 different standard sizes, from the R-1,
machine, to the R-21-S, the strongest section bending machine
in the world! The machines are always more powerful and more
heavily proportioned in terms of frame, shaft size, bearings and
drive torque than machines from other suppliers. CNC controls
and a wide array of options are available for all models.
ROUNDO ROLLS OVER THE COMPETITION BY FEATURING:
Proportioned Frame - for added strength and rigidity
Diameter Roll Shafts - to minimize deflection, improving results
Shaft Bearings - for greatest efficiency and long life
Torque - means fewer passes and less deformation
Bending Roll Force - generated by the rolls, providing
the largest section modulus capacity
Guide Rolls - to efficiently take the twist out of the
TWO BROAD RANGES OF ROUNDO
R-1 to R-6 are basic machines
for all types of section bending. The guide rolls are
manually adjusted and fixed to the swing arms.
R-2-S to R-21-S offer enhanced
versatility due to the unique design of the multi-directional
hydraulic guide rolls and increased capacity.
MAIN ADVANTAGES WITH ROUNDO BENDING MACHINES
The main frame on all ROUNDO bending machines is welded steel construction, machined
and line bored using the heaviest components of any comparable
machine for added strength and rigidity. ROUNDO is the only
manufacturer who stress-relieves every frame after welding.
ROUNDO roll shafts are made from high-strength chrome-nickel alloy
steel, and are the largest diameter shafts of any comparable
machine. These heavily proportioned shafts help minimize
deflection, resulting in improved bending. The roll shafts are journalled in oversized SKF roller bearings for greatest
efficiency and long life. The standard tooling is a combination
set for bending angles both leg-out and leg-in, flat bar on flat
and on edge, T-bar stem-out and stem-in as well as stem-down,
small square bar and even small solid round bar. Normally, no
additional spacers are required.
ROUNDO angle bending
machines provide the greatest drive torque of any comparable
machine. Greater drive torque means the section can
generally be rolled in fewer passes, often resulting in less
deformation to the section being rolled. All three rolls are
driven at all times. The rotation speed on all models is
generally 23 feet/min, considerably faster than other comparable
machines, and high speed packages are also available!
The two lower rolls are individually adjusted by hydraulic
cylinders. The rolls are sized to allow ROUNDO angle
bending rolls to generate more bending power than any
comparable machine, providing the largest section modulus
ROUNDO angle bending
machines feature the largest, most powerful guide rolls
available on the market. This allows them to take the twist out
of the most massive sections within the capacity of the machine.
The hardened steel guide rolls, including "leg-in" guide rolls,
are standard on every model. 4-directional hydraulically powered Guide Rolls are standard
on Models R2S to R4S and 6-directional hydraulically powered
Guide Rolls are standard with Models R5S and larger.
ROUNDO machines can be found all
across the world including over 4000 in North America alone. Our
featured customers include a large percentage of Fortune 500

The First with a CNC System
In 1985, ROUNDO was the first to develop CNC controls specifically
adapted to bending machines. Since then, we have
steadily enhanced and expanded the capabilities of our
systems, allowing us to maintain our position as the
world leader in this area as well.
"The ROUNDO CNC control system can position the rolls to
within ± 0.004”, even under varying loads. These tight
tolerances are unmatched by any competitive machine."
ROUNDO CNC Circa 1985
| Unlimited Capacity
The ROUNDO control systems
have practically unlimited capacity regarding the number
of programs and the size of each program. The computer
in the CNC system can be connected to the customer’s
network, providing a simple means of data backup. The
software can also be installed in an office PC, allowing
finished bending programs to be created in advance. This
allows the machine to be available for production for a
longer period of time.
The ROUNDO wCNC² Control is
a PC-based CNC control running under Microsoft® XP,
providing an operator-friendly graphical interface. This
highly advanced and powerful system can control up to 24
axes, including the main bending rolls, and any type of
optional equipment. Also communication with peripheral
units such as industrial robots or material handling
systems is easily integrated in our unique system.
Always One Step Ahead
The ROUNDO wCNC² Control
software includes a library of bending wizards to
rapidly produce good parts. Even short runs can be
efficiently rolled using this system. The CNC Control is
available for all models.
|The ROUNDO RLC/3 Logic
Control System is a PLC based control system designed
and developed normally for small section and plate
bending machines. This system can control up to 7-axes
and the possibility to use USB memory allows infinite
number of bending programs.
The ROUNDO RLC/1 Position
Control System is a basic positioning control with
possibility to preset two values for each axis. The
positioning control automatically stops the movement of
the bending roll when the pre-set value is reached. The
system is designed to make repetitive bends.
A few important questions to which you
should demand answers before purchasing a plate or
angle bending machine:
-Are there references from satisfied customers
concerning service, life and quality? There are
over 4000 ROUNDO Bending Rolls in North America. Trilogy
Machinery handles the parts, service and support for
each one of them. We will gladly provide you with an
extensive list of customers in your area for reference.
-Will the machine meet your present as well as your
future needs? Not only will the ROUNDO roll out
last the competition but most can be upgraded with the
latest CNC controls and equipment.
-To what extent is technical expertise, support and
service provided? If their answer is "We can ask
the factory", that should be an immediate indication to
look elsewhere. The staff at Trilogy have more
direct/hands-on experience than any other distributor in
-What is the cost of the machine distributed over its
expected service life? While many competitors
claim to save you money initially, over time the expense
to maintain their machines may be drastic. ROUNDO is the
most popular bending machine on the used market solely
because of its PROVEN long service life.
