Round Bending Machines : Four rolls Basic

The round bending machine basic in rour roller design (RBB) is the entry model into the world of bending of high-quality round tubes. Through the four-roll technology and SPS which is enabling the pre- or re-bending, sheet metal tubes can be produced which can be welded on longitudinal seam welding machine with a laser or WIG.
 
Infinitely variable feed motors provide the pre-bending, the bending angle and angular deflection plate. The plate thickness is adjusted by pneumatic cylinders. The lateral stop for pre-bending is free-standing. Control panel with PLC control and touch screen.
 
 
Bending rolls are are out of high strength material and can be hardened and ground on customers demand.
 
 
 
The RBB is available in the same standard measurements as the RBA
 
Example sizes RBB 42-70

* The sheet thickness refers to a material with a tensile strenght of  400 N/mm²         
and an elastic limit of 250 N/mm²!
