NATIONAL MANUAL BENDING ROLLS are principally used for rolling tubes/cylinders in sheet metal. The metal is ‘pinched’ between two rolls and curves as it comes into contact with the third (back) forming roll. These rolls have a 1020mm roll length, 50mm roll diameter and can accommodate mild steel up to 1.2mm thick. The rolls are bottom slip, with an Edwards style fabricated steel frame.
This machine is now sold.
