PCT No. PCT/SU81/00066 Sec. 371 Date Jun. 10, 1982 Sec. 102(e) Date Jun. 10, 1982 PCT Filed Jul. 30, 1981 PCT Pub. No. WO82/02009 PCT Pub. Date Jun. 24, 1982.A device for corrugating a sheet material with forming staggered cut corrugations, comprising a mechanism 1 for feeding a sheet material 2 to at least two punches 3, 4. The punches 3, 4 are mounted for reciprocating motion on both sides of the material 2 in the plane perpendicular to the plane of the material 2 and over the surface of the material 2 at right angles to the direction of its feeding. The device is provided with dies 12, 13 disposed on both sides of the punches 3, 4 in the direction of feeding the material 2, with a clearance being not less than the thickness of the material 2. The dies 12, 13 are adapted to reciprocate relative to the punches 3, 4 at right angles to the plane of the material 2 such that in the process of forming the corrugations the punches 3, 4 are forced in the material 2 between the oppositely lying dies. |
