Moreover, the rolls have a corrugated profile in the peripheral direction of the outer surface, as a result of which the original plate is deformed in sections to obtain a wave-shaped plate. Moreover, the corresponding profile of the used rolls contains half-waves, which follow each other in the peripheral direction and which are at least partially characterized by different extensions in the peripheral direction.
