4R 4-roll section bending

ROUNDO also supplies a range of section bending machines with four rolls. This type of machine is perfect for producing body shell components and similar parts where three-dimensional bending is required. Sections are pinched between top and lower roll, which are also the driven rolls. This offers the possibility for pre-bending with extremely short remaining straight ends.
Perfect solution for vehicle chassis components.

All ROUNDO section bending machines offer:

Two-roll drive to minimize the risk of slipping.
Hydraulic drive with infinitely variable speed control.
Hydraulic adjustment of the lower roll.
Standard rolls for flat bars, angle bars, T-bars and square bars.

For more information, please see our attached brochure.
