Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section.The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained.

When sheet metal is inserted between two such rolls, the urethane wraps the sheet metal tightly against the steel roll (similar to a radius forming urethane press brake die), and since the urethane roller is driven, the sheet metal is roll formed into a precise radius. Allowing for natural spring back of the material, this radius remains uniform irrespective of whether the shape of the part ...

Immediately following the cut-to-length line leveler, a pair of large driven pinch rolls provide pulling tension, thus moving the neutral fiber closer to the inside radius of the metal's cross section in the leveler as discussed previously (see Figure 3). The addition of some tension extends the maximum capacity upward and the minimum capacity downward. This is designed to provide increased ...
