Abstract
For the corrugated deformation of a flat sheet of material, an upper row (2) of shaping tools (4) is pressed against a lower row (3) of shaping tools (5). The shaping tools of both the rows are, with that, also simultaneously pushed together so that they trace the shortening of the sheet of material during the deformation. Thus, the situation is achieved where no relative displacement between the sheet of material and the facing sides (6, 6') of the shaping tools (4 and 5) takes place, also in the case of numerous corrugations of relatively great height. The lower row of shaping tools is arranged on a rotor, whilst the upper row is fixed at a working station within the area of rotation of the rotor.
