A machine (1) for shaping profiled metal sheet (100) includes a number of shaping stations (10A, 10B, etc.). The shaping stations include an upper beam (11) and lower beam (12). The beams (11, 12) carry groups (31 - 34 and 41 - 44) of rotatable shaping rolls (31a, 41a, etc). By revolving the beams in different positions different profile variants can be produced. Metal-sheet feed stations (60A, 60B, etc.) are located between the shaping stations (10). The feeding stations (60) include a driven feed roller (61) and pressure rollers (75). Actuating devices (79) are arranged to move the pressure rollers (75) in a direction transversely to the direction (A) in which the metal sheet is advanced and to a position within a region in which the metal sheet (100) of the currently produced profile variant abuts the feed roller (61). |
