3 Roll Bending Machine HR3WS – Variable Geometry


Plate rolling machine, ‘Variable Geometry’ manufactured in Italy, incorporating the latest plate rolling design and technologically, with advanced technical equipment, excellent build quality, reliability of performance.

Italian excellence’ – perfection without compromise



Why choose the 3 Roll Bending Machine HR3WS  – Variable Geometry?

3 roll variable axis plate bending machines are used for bending medium to thick plates. They are very precise and easy to use. There are advantages by using this system where the two side rolls move horizontally – left and right, while the top roll moves up and down. When feeding the material into the machine it does not tilt up as it would on a double pinch three roll bender but stays parallel to the ground allowing easier and safer material handling. When positioning the side rolls at their farthest position, you can increase the rolling capacity by up to 50% more than on a traditional 3 or 4 roll bending machine. Three driving rolls offer full control over the bending process.

The horizontal movement of the 2 side rolls, with a vertical movement of the top roll, for pre-bending

Hydraulic 3 roll, variable geometry plate bending rolls, the ultimate ‘heavy-duty’ plate rolling machine for plate rolling at the max thickness, using variable geometry technology NC or CNC options, plus ancillary equipment, i.e. rolled cylinder central & side supports, material loading unloading tables, manual or power-operated.

It is the heart of the machines performance; it’s what makes a ROCCIA plate roll different from the competition. Roll camber calculation. Roll camber is required to counter act roll deflection that occurs as bending forces are applied, so as to ensure a perfect closing of the longitudinal seam, it is a vitally important factor. If the camber is calculated incorrectly, the result will be, (1) a barrel shaped cylinder ie not closing perfectly along the longitudinal seam, gap in the middle, (2) an hour glass shaped cylinder, the longitudinal seam touching in the middle, but not at the ends. ROCCIA roll dimensioning camber calculation are done on sophisticated 3D cad software that produces all the critical data required for every step of the rolling process. Roll calculations are seldom to standard formulae, no, they are calculated around customer requirements, this being, material type, mechanical strength, material thickness, the rolls cylinder length dimension. Only this way can we grant the performance and the precision of the plate rolling machine we manufacture for you.

The wide BASED ANGLED FRAME bulkhead construction is designed to bring increased stability to the whole structure, designed by ROCCIA engineers to absorb side thrust forces during plate rolling cycles.


As place your hands on the control console, you will immediately be aware that all the controls are exactly where you would expect them to be.

A ROCCIA 3 roll machine utilizes 3 driven rolls to ensure the rolling torque power transfer. Single unit high torque hydraulic MOTORS/PLANETARY GEARBOXES are directly mounted onto each driving roll to ensure a smooth feed through of the plate, there is no loss of power normally associated with secondary transmissions, plus the added benefit of one less gearbox to maintain.

By having THREE INDIPENDENTLY DRIVEN ROLLS it assures a firm and smooth feeding of the material through the machine which is a key feature of our HR3WS models.

This system is clean, maintenance free and efficient. By not using gears or chains you will not have a loss in torque as you would in an ordinary transmission driven plate bender. The hydraulic motors and gear boxes are coupled directly on the rolls.

Technology and Innovation

  • EBD (Electronic Balancing Device)
    The most technologically advanced system to precisely couple the two hydraulic pistons controling the side roll positions. Tested and used on press brakes for many years, the EBD system offers roll  positioning precision without equal.
  • LVS (Limitless variable speed)
    The two side bending rolls and and the rotation of the top & bottom rolls have a variable speed feature based upon the use of proportional valves.  Control of material surface speed & bending roll positioning has never been easier.
  • DTS (Double side tilting system)
    It gives not only the possibility to tilt the bending rolls in one side to bend cones but it is reversible.
    This means that the bending rolls can be tilted in two directions and be used for straightening,
    or aligning a  rolled shell, tube, tank, that has some defects.
    The Plate bending roll features the SMART SELECTOR system, this allows the plate rolling machine operator to select any ancillary function he requires to control, additionally the system is designed to give you the purchaser the ongoing flexibility to add some of the optional equipment, at a later date the SMART SELECTOR system ensures that everything is in place for the up grade

All Sheet Metal Rolling Machines are fully supported by our service team,
probably the largest independent dealer service team in the UK.
Experienced, reliable, professional.
