Abstract
A beam with a hat-shaped profile with a cross-section that varies along its length is successively formed from a plane sheet metal strip using a roll-forming machine with a number of forming stations. The forming stations () have a pair of clamping rollers (and) for each side flange () and support rollers () for the central flange. The pairs of clamping rollers in the forming stations can be displaced both horizontally and vertically during a forming operation, and the support rollers () can be displaced vertically and they can be displaced individually in a sideways direction. All four corners (-) of the hat-shaped beam are formed at the same time, whereby the corners are folded on the peripheral edges of the clamping rollers and support rollers. Not only the axes of the pairs of clamping rollers but also of the support rollers can be turned in order to adapt to the corners that are being formed.
