Abstract: In order to corrugate or pleat between forming rolls sheet metal irrespective of its ductility while containing the blister formed at the end of the corrugation or pleat in the course of formation, the sheet is heated locally, at a short distance upstream of the rolls, to a temperature capable of rendering the sheet ductile. The rolls are protected against harmful heating by the distance between the heating region and the forming rolls.
