SHEET BENDING MACHINE with four symmetric roller technology R4 Next Gen
Thick materials without compromise... but not only that!2, 3 or 4 rollers? Understand the specific features of each technology
There is no such thing as the right or wrong architecture for a machine.
Each roller has its speciality.
Enclosed you will find the different types of processes and your material and performance requirements, grouped by machine type:
- Mass production capability with the R2
- Versatility and performance with the R3
- Mastery of heavy thicknesses and an integration into your processes for the R4
The solution to your problem... and more
Created in the 1980s alongside similar types of hydraulic machine, the R4C four-roller sheet bending machine was developed especially to handle thick materials, always keeping the plate clamped between two rollers.
Today it’s the most popular machine on the market, largely because others have been considerably simplified, often to create a low-cost machine with just one or two powered rollers, alignment control by torsion bar, planetary guide system, etc.
We didn’t follow that trend because it diminished the performance of those machines.
That’s why the R4C sheet bending machine is still a four-roller machine that makes no compromises: four powered rollers with linear guide system for top performance (prebending, power, etc.) and agility in all situations.
We have equipped it with an innovative clamp control technology to limit the effects of lamination of the plate (pressure and position control).
Our four-roller technology is especially recommended for:
- thick materials (above 20 mm)
- mass-produced parts
- tanks with multiple radii
- integration into a global process: loading table, evacuation, welding, etc.
It is not recommended for use on very thin sheets or for cone rolling; the R3 performs well for those purposes.
R4 Next Gen: a new standard to support your industrial challenges and evolution
- Architecture with four independent powered rollers mounted on bronze rings
- Connectivity 4.0 for remote operation and interfacing with your organisation
- Pressure and position control of the clamping rollers to limit deformation and marking of thin sheets
- Use with three or four rollers to take advantage of each of the technologies (two machines in one!)
- Easyroll ready as standard (all of our machines are upgradeable by a Plug & Play console change without other modifications)
- Easyroll: our patented software! Like a GPS to guide you through the bending process.
Updates and new versions are provided free of charge. - AIR: Artificial intelligence for Roll bending machine, an extension of Easyroll since V4

PICOT ENGINEERS have developed an innovative software, a real GPS dedicated for roll bending
Smart material database
All the cards to roll better,
with complete peace of mind
The AIR algorithm and the intelligent material base of Easyroll® are the two pillars of the technology developed and patented by AMB PICOT to predict the rolling performance with unrivalled reliability.
This technology increases the capabilities and scalability of the digital support offered to the user, notably through simulation functions, programming and coning support, springback prediction on 3-roll machines, etc.
Predictive learning
patented technology
Learn, predict and optimise
rolling performance
The characteristics and thicknesses of materials (steel, stainless steel…) and their typical advanced rolling behaviour are integrated in easyroll®. This data can be modified or enhanced by software updates or customised by the user.
AIR: Artificial Intelligence
for Rollbending machine
Improve and capitalise
Rolling experience
easyroll® features an intelligent expert algorithm that helps both the user and the machine to correct errors, stabilises programme performance and transforms personal experience into modelable, reproducible know-how. Yielding point, breaking point, unwanted deformation… AIR goes beyond a simple material correction update and allows you to adapt your easyroll® to your specific needs (fine tolerances, tanks, aircraft fuselage…).
