Patent ID: 8302444

Claim:
Method for folding an edge of a sheet metal component, wherein the edge is brought into contact with an adjoining part of the sheet metal component by means of a folding roller guided along the edge, wherein a roller which is conically contoured on an outer surface and having an axis of rotation inclined with respect to a plane of the sheet metal component is used as the folding roller, wherein a folding roller axis of rotation is also inclined with respect to a movement direction, wherein cylindrical edge regions adjoin a conical region of the folding roller, wherein the folding roller is inclined in an oblique manner with respect to its movement direction along the fold by guiding and inclining means such that as the folding roller moves it first strikes against the edge with its advancing side of its cylindrical outer region having a largest diameter and thus triggers the folding process, wherein the edge then slides over the conical region, wherein the edge is further folded until it is finally pressed to contact the flat sheet metal component by the cylindrical region having a smallest diameter.
