All machines have unique features needed for high precision and versatility prebending of both the leading and trailing edge. ln many cases, the remaining flat end is as short as one time the plate thickness. Fully hydraulic, infinitely variable speed drive and adjustment of the rolls.
Highest drive torque of any competitive machine.
Frames made of high strength steel, fully welded and stress relieved before machining to have sufficient strength to absorb bending forces and to achieve highest possible accuracy. All purpose machine with wide working range. Excellent for cone bending.

Most Versatile Plate Roll
The ROUNDO PS rolls aгe the most versatile yet cost effective bending rolls available today. The pinch pyramid design provides excellent prebending capabilities of both ends of the plate without the need to remove, turn, and re insert the plate. Yet, by positioning the rolls in the pyramid symmetric configuration, maximum bending capacity can be obtained, as well as maximum cone bending capabilities. The ROUNDO PS rolls provide a large opening between the upper and lower rolls, permitting heavy bars and even such unusual items as stair stringers for spiral staircases to be rolled. Versatility can be further expanded by the addition of attachments to roll flat
Bar on edge and, on many models, angle iron, T bar, channel, pіpe and other sections. Heaviest Frame Components. The main frame on all ROUNDO PS rolls is welded steel construction, machined and line bored using the heaviest components of any competitive machine for added strength and rigidity. ROUNDO is the only manufacturer who stress relieves every frame after welding. Largest Rolls & Roll Shaft Bearings
The rolls are made from high carbon content steel forgings for maximum surface hardness and are the largest diameter rolls of any comparable machine. To achieve optimum bending results, the rolls are crowned in a special manner to compensate for the deflection under load. The amount of crowning is calculated by computer to achieve the largest possible thickness range. The rolls are journalled in oversized SKF roller bearings for greatest effıciency and long life.

Highest Drive Torque
ROUNDO PS rolls provide the greatest drive torque of any comparable machine. Greater drive torque means the plate can generally be rolled in fewer passes to a tighter diameter. All three rolls are driven at all times. Smaller models incorporate a central hydraulic motor, and larger machines have separate hydraulic motors for each roll. Electronically controlled infinitely variable rolling speeds give the operator full control of the bending process, and are standard on every ROUNDO PS roll.
Greatest Bending Roll Force
The two lower rolls are individually adjusted by hydraulic cylinders at both ends of the rolls. These are sized to allow ROUNDO PS rolls to generate more bending power than any comparable machine. Parallelism of the rolls is one of the most crucial factors in achieving good bending results. This is assured on all ROUNDO PS rolls, even under maximum load, by the use of series connected cylinders on smaller machines and digital controls on larger machines. In addition, the lower rolls, and optionally even the top roll, can be tilted to facilitate the widest cone rolling capacity. Massive Drop End
The drop end, or end yoke, is very heavily proportioned and hinged at two swiveling points placed so that they counteract the forces from the lower rolls against the top roll. This construction eliminates any tendency for the drop end to twist. User Friendly Controls
Portable controls are utilized as operating controls on the various models. They are designed and arranged to enable the operator to stand at the position best suited for viewing and safety during rolling. Electronic digital readouts or dial indicators aгe provided to facilitate repetitìve rolling operations. Tilting the rolls for cone rolling is accomplished by push button controls.
Excellent for Cone Bending
The cone bending attachment is mounted on the upper roll at the drop end and is used to slow the small end of the pre cut cone plate, giving it a lower speed than the large end as they move through the machine. With this attachment and standard power tilting of the lower rolls, cone bending is greatly facilitated. To further enhance cone bending, the machine can be optionally equipped with a tiltable top roll.

Optional Equipment
ROUNDO PS rolls are the best equipped and most versatile in the industry, yet there are applications where the addition of options such as material handling equipment, bar bending attachments, special top rolls, or special controls such as ROUNDO'S exclusive are called for. For those applications, we offer the following
interchangeabIe Top Roll
When rolling parts to diameters smaller than the standard top roll will permit, an interchangeable top roll may be installed. This smaller diameter top roll can be easily exchanged with the standard top roll, further enhancing the machine's versatility. lnterchangeable top rolls with special crowning or special machining to accommodate unusual applications can also be installed.
Overhead and Side supports
All PS rolls can be equipped with hydraulically operated side supports on one or both sides to support the material as it enters or leaves the machine. An adjustable top support to support the material from overhead helps reduce deformation of the rolled plate. These supports can be ordered mounted on the machine when shipped from the ROUNDO factory, or added later as requirements warrant. This flexibility allows the machine to be equipped in a manner that enhances efficiency, safety and productivity while preserving capital.
Hardened, Ground and Polished Rolls. For stainless steels and other materials with high strength limits, or when frequent cone bending is anticipated, hardened and ground rolls are recommended. To avoid cracking and warping issues, the rolls are hardened using the preferred 7 step surface hardening process, followed by precision grinding and polishing. Bar Bending and Angle Bending Attachment. Permanently mounted inboard of the drop and not requiring removal for general plate rolling, the bar bending attachment provides the largest capacity of any competitive machine for rolling flat bar the hard way. On machines up to Ps 310, a set of collars can be added to this attachment to permit leg in and leg out rolling of T bar and angles tack welded together to form a T bar, pipe, channels flanges in and flanges out and other sections.

ROUNDO CNC Controls
The ROUND Control is a PC based CNC control running on Microsoft Windows, providing an operator friendly graphical interface. This highly advanced and powerful system can control up to 12 axes, including the main bending rolls, the powered support devices, and even infeed and outfeed devices. Smooth blending of
radil by simultaneous rotation and roll adjustment greatly improves the quality of all parts with multiple radio.
The ROUNDO 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.
ROUNDO PLC Controls
The ROUNDO Logic Control System is a PLC based control system designed and developed especially for plate and section bending machines. This system can control up to four axes usually roll rotation and adjustment. Optionally, two of these axes can be
controlled simultaneously, producing smooth blending of different radio. Programming may be done via integrated keyboard or with fast teach in function.
Other Control options
The ROUNDO Position Control System is a basic positioning control with 2 pre set values for each axis one for up and one for down. The positioning control automatically stops the movement of the bending roll when the pre set value is reached. This system is
designed to make repetitive bends, eliminating the need to manually stop at all required positions.
Electronic digital Readouts
In place of the standard dial indicators. They are mounted in the portable control station and are available for all models to improve the positioning accuracy of the bending rolls when adjusted by the operator. To further enhance productivity, especially for cone rolling, double
digital readouts showing the positions of each end of each lower roll are available.
