NC-controlled multi-roll bending machine

different diameters can be produced without mechanical refitting

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 rollforming 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

No changeover

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