A sheet bending machine rolls a steel plate or other type of material sheet through two or more rollers into cylindrical or conical shapes. This can be done mechanically, electrically or hydraulically.
A profile bender bends various profiles, such as angle profiles, I-profiles, wave profiles, H-profiles, etc. The profiles are rolled between three rollers until they have the desired shape.
There are manual profile rollers, but also with hydraulic drive.
