Our roll bending machines fulfil all the requirements of modern sheet metalworking. Our wide range of options offers excellent flexibility in handling different diameters and geometries. This allows you to manufacture round, oval and polygonal sheets to match your specific requirements. The pre-programmed options on NC controlled round bending machines offer a large selection of pre-defined shapes you can access quickly and easily using a library. Using two or more rollers ensures high quality and good reproducibility.

Do you need advice on choosing the right roll bending machine? Our experts will be happy to help you.

Process
The program-controlled 2-roll bending machines process is fully-automatic and guaranteesa high repeatability. All processparameters can be stored forlater use.

Modular configuration
The addition of a destacker andpush-out unit reduces manpower requirements.

Multiple production
Increase the output: depending on the blank size, multiple parts can be rolled at the same time.

Top results
Use of an upper roller with support enables high-quality production of small diameter tubes.

The ideal roll bending solution for all tube shapes: round, oval or polygonal.

Ideal for integration in a fully-automatic production line or as a stand alone unit.

Geometry freedom

Round, oval and polygonal tubes can be shaped using this technology

Tube roll bending unit

Top-quality roll bending results are achieved thanks to the 2-roller bending technology

Diameters

The roll bending cell is available in different diameter variants

Programming

New products can be set quickly by selecting a predefined shape from the library

No tooling means no change-over time loss
Diameter changes are made at the push of a button.
Changes in material characteristics can be compensated through parameter settings.

High-tech roll bending machine for a fully automated and flexible manufacturing of tubes up to 2000 mm tube length and radius greater than 30 mm

The multi-roll bending principle

The blank is pushed between the upper and lower roller and the bending process starts. After roll forming, the aligned tube is pushed out of the roll former gap-orientated (weld gap is positioned on a catch bar). As the lower rollers are adjustable in Z and Y direction, the straight section at beginning and end of tube is limited to a minimum.

No tooling means no change-over time loss. Diameter changes are made at the push of a button. Changes in material characteristics can be compensated through parameter settings.

Automation

Automation modules are available for the multiroller as a stand-alone roll-bending machine or in combination with a welding machine

NC-controlled multi-roll bending machine

Different diameters are produced without mechanical changeover
 

No changeover

The conversion to another diameter is carried out by pushing a button – saving time and money

Small diameters

Bending of small diameters and difficult to form materials.
