A roll-forming machine includes in line a device (11) for unwinding metal strip (10) from a strip reel (12), a strip cutter (18), and a roll-forming section (30; 90). The roll-forming section includes a row of forming stations that include forming rolls that are carried by shafts which are supported on a respective one side of the sheet section. Each row of forming stations includes an edge cutter (58, 59; 102, 103) and a first forming station mounted on a common movable carrier (31, 32; 100, 101), for collective movement. The angle of the carrier relative to the longitudinal axis of the forming section can be adjusted and the carrier can be moved in a parallel manner transversely to said longitudinal axis so as to enable said movement and said angular adjustment of these forming stations to be achieved simultaneously.
