MRMS Mechanical 3-Roll Plate Bending Machine
The MRMS mechanical 3-roll plate bending machine from EBR METAL has an initial-pinch roll layout. A planetary reducer drives the rolls, a motor adjusts the back roll, and the drop-end opens by hand.
The frames are welded steel, and a conical bending device is standard. The range has 21 models with useful lengths from 1,050 to 3,050 mm.
• Useful length 1050–3050 mm • Rolls Ø130–220 mm · Motorised back roll • Optional NC Control

- Rolls Ø 130-220 mm
- Motorized back roll
- Optional NC Control
How the MRMS Works
The plate is gripped between the top and bottom rolls while the back roll bends it, so the MRMS can pre-bend the plate edge. A brake motor gives precise bending, and the back roll is positioned by its own motor.
The MRMS has no hydraulic system. For hydraulic roll positioning and a hydraulic drop-end, see the MRMH.

NC Control
Optional NC control lets the operator program roll positions and save bending sequences for repeat work. In teach mode, the operator bends a part while the controller records each step. The saved program can then be recalled to repeat the sequence on subsequent parts.

Plate bending capacities are given for 260 N/mm² plate yield strength.
In the pre-bending and bending capacity columns, a/b gives the capacity at bending diameters of 1.5× and 5× the top roll diameter, respectively.
Choosing the MRMS
Choose the MRMS for initial-pinch rolling with a mechanical drive. Compared with the MRM, it has welded steel frames, a planetary reducer and a motorised back roll. Tank and silo shells and machinery bodies can be rolled on the MRMS, depending on thickness, working length and diameter.
With the optional profile and section roll set, the MRMS can also bend profiles on extended roll shafts. For dedicated profile and pipe bending, see Profile Bending Machines.

Frequently Asked Questions About MRMS
Is the MRMS hydraulic?
No. The MRMS has a mechanical drive through a planetary reducer, a motorised back roll and a manually opened drop-end. The MRMH is the hydraulic model.
Can the MRMS bend profiles or pipes?
Yes, with the optional profile and section bending roll set on extended roll shafts.
Can the MRMS roll aluminium composite panels?
Yes, with the optional plastic-coated top roll.
Is NC control available on the MRMS?
Yes. NC control is available as an option. Its teach mode can save a bending sequence for reuse.
