Title:
DEVICE FOR CORRUGATING SHEET MATERIAL
Document Type and Number:
WIPO Patent Application WO/1982/002009
Kind Code:
A1
Abstract:
A device for corrugating a sheet material with forming staggered splitted corrugations comprises a mechanism (1) for feeding the sheet material (2) to at least two punches (3, 4). The punches (3, 4) are mounted with the possibility of their reciprocal movements on both sides of the material (2), along a plane which is perpendicular to the plane of the material (2) and along the plane of the material (2) perpendicularly to the feed direction. The device is provided with matrices (12, 13) located on both sides of the punches (3, 4) along the feed direction of the material (2) with a gap equal to at least the thickness of the material (2). The matrices (12, 13) are mounted with the possibility of their reciprocal movements in relation to the punches (3, 4) perpendicularly to the plane of the material (2) so that, when forming the corrugations, the punches (3, 4) are pressing the material (2) between the opposite matrices.
