MRD / RD 3-Roll Plate Bending Machines
The MRD / RD 3-roll plate bending machine comes in two versions of the same cast-iron design: the MRD is motorised and the RD is turned by hand. Both roll sheet from 3.0 mm on the shortest model to 1.5 mm on the longest.
A conical bending device is standard on both versions. Each comes in four sizes with useful lengths from 1,050 to 2,050 mm.
• Useful length 1,050–2,050 mm • Capacity 1.5–3.0 mm • Rolls Ø90–95 mm • Motorised (MRD) or manual (RD)

MRD or RD
On the MRD, a single gearbox and gear system drive the top and bottom rolls, a brake motor gives precise bending, and the operator works from a mobile foot-pedal control panel. The RD has the same frame sizes and is turned by hand, so it needs no electrical supply.

Plate bending capacities are given for 260 N/mm² plate yield strength.
Minimum bending diameter: top roll diameter × 1.5.
Choosing Between MRD and RD
Both versions share the same sizes and capacities. Choose the MRD, a motorised 3-roll plate bending machine with a brake motor and foot-pedal control, for powered rolling. Choose the RD, the manual 3-roll plate bending machine of the pair, where hand operation is preferred. Typical work includes ventilation ducts and parts, stove pipes and light cylindrical parts in 1.5–3.0 mm sheet, depending on thickness, working length and diameter. For sheet up to 2.0 mm, see the MSR | SR machines.

Frequently Asked Questions About MRD | RD
What is the difference between MRD and RD?
The MRD is the motorised version, with a brake motor and a foot-pedal control panel. The RD is the manual version in the same sizes and capacities, turned by hand.
Can the MRD and RD roll cones?
Yes. The conical bending device is standard on both versions.
What thickness can the MRD | RD roll?
From 3.0 mm on the 1,050 mm model to 1.5 mm on the 2,050 mm model, for 260 N/mm² plate yield strength.
Does the RD need a power supply?
No. The RD is operated by hand.
