  • Method of bending shaped metal sheet and apparatus for carrying out the method
    Patent number: 4580433
    Abstract: This invention relates to the bending of shaped sheet metal, which shows alternatingly occurring longitudinal ridges and valleys, the lateral portions of which constitute lateral portions of the ridges, about an axis, which extends perpendicularly to the longitudinal direction of the ridges and valleys and is in parallel with the plane of the sheet. Known methods of bending such shaped sheet metal have proved to have certain limitations with respect to applicability and smallest bending radius to be obtained in one or more coherent bending moments or steps. For eliminating these shortcomings a method of bending shaped sheet metal is proposed, at which the bending takes place in at least two subsequent moments or steps.
    Type: Grant
