Abstract

See full text

In a method of forming a rim on a lamp reflector, a forming roller is positioned on one side of the reflector rim to be formed and a support roller is positioned on the other side. The reflector is rotated about its center axis and the rollers are rotated with the same circumferential speed as the reflector rim. Then the rollers are moved such relative to each other and to the reflector that the rim is flanged between the rollers. The forming roller is moved such that the final tangent line of the circumferential face of this roller to the reflector rim is tilted about a pivot point which is positioned substantially on the bending line of the reflector rim. The invention also includes an apparatus for performing this method.
