Abstract
The invention relates to a process and an apparatus for producing a profiled sheet, in which the sheet is provided with a corrugation which runs obliquely with respect to the edges of the sheet and has a substantially constant angle of inclination. At least one edge region of the sheet is deformed by means of a ram-like deformation tool () which is alternately brought into contact with the edge region and removed from the edge region.
