Flanging device and flanging method with component protection

A flanging device for roll-flanging a rim of a component, said flanging device including:

• a) a flanging head;
• b) a first flanging roller which is mounted by the flanging head and can be rolled off on the rim during roll-flanging;
• and
• c) a second flanging roller which is mounted by the flanging head and forms a counter pressure roller for the first flanging roller;
• wherein the flanging device includes a stable protective structure which is or can be fastened to the component and forms a rolling surface for one of the flanging rollers or supports a rolling surface, wherein the protective structure includes a fastening anparatus for fastening to the component, and wherein the flanging head mounts a sensing element and the protective structure forms a guiding path for guiding the sensing element, wherein the guiding path is shaped to follow the course of a flanging edge to be formed.
