<p>By the method a sheet (1) is moved in a device by means of a row of rollers (2), the surfaces of which form a rolling path (11) and a shaping curve for the sheet (1). The rollers move so that the shaping curve gradually changes from a substantially plane initial shape to a desired curved shape and that the shaping curve is displaced along the rolling path (11).</p> |
