Roller folding method for folding marginal area of sheet metal component, involves pressurizing folding area in edge area of sheet metal component by folding roller in direction of supporting area

摘要

The roller folding method involves pressurizing a folding area (10) in an edge area (2) of a sheet metal component (3) by a folding roller (6) in a direction of supporting area (12). The folding area passes over a folded sheet (11) in a supporting area that lies opposite to the folding area. The folding roller lies at a folding area with a radial outer lying folding surface (13) during folding. An independent claim is also included for a folding roller for a roller folding device for folding an edge portion of a sheet metal component, particularly an outer cladding part of a motor vehicle.
