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.

Abstract: A machine for corrugating thin sheet metal comprising two rolls at a first work station, at least two rolls at a second work station, tracking lateral rollers, a corrugation-forming rake mounted on each roll, at least one clamping roll upstream of one work station, a shell of sheet metal being rotatable between the two rakes of each work station, each work station effecting through the pressure of the first-rake roller a bending of the metal to form a half-profile of the corrugation of each successive helix turn, the successive turns screwing helixfashion into the rakes whereby to obtain a corrugated shell.
