Abstract

The aim of the invention is to provide a method for producing a fold on a sheet metal element (100) whereby the outer radius (RA) of the fold can be predetermined substantially independently of the material thickness of the sheet metal element (100). For this purpose, the inventive method comprises the following steps: preprofiling the sheet metal element (100) in such a manner as to produce, on a first face (104) of the sheet metal element (100), a recess (106) which extends along a desired fold line, and, on a second face of the sheet metal element, a projection (110) which also extends along the desired fold line and is opposite the recess; and bending the sheet metal element (100) on the fold line along which the recess (106) and the projection (110) extend, thereby producing the fold.
