DEVICE FOR CORRUGATING SHEET MATERIAL Abstract of the Disclosure A device for corrugating a sheet material with forming staggered cut corrugations. The device comprises at least two punches adapted for reciprocating motion on both sides of the sheet material in the plane perpendicular to the plane of the material. The punches are also adapted for reciprocating motion over the surface of the material in the plane perpendicular to the direction of its feeding. The device is provided with dies disposed on both sides of the punches in the direction of the material feeding, with a clearance being not less than the thickness of the material. The dies are also adapted for re- ciprocating motion relative to the punches in the plane per- pendicular to the surface of the material such that in the process of forming the corrugations the punches force in the material between the oppositely lying dies.
