Abstract:
A method for producing a rim having a rim base coupled to a rim disk for a pneumatic tire, wherein the method for forming the rim base comprises:placing a ring shaped blank into a compression mold constructed as a cavity; pressing the blank by at least one pressure roller against the at least partially contoured interior side of the compression mold cavity to produce the rim base with a rear rim flange; and, wherein the rim base is produced from a round blank; and from the round blank fixed between the compression mold constructed as a cavity and a pressure pad and by means of one or several compression rollers, placing the round blank against an exterior compression lining, a first drawn element is produced; the first drawn element is fixed to a rim disk; subsequently, the rim disk with the first drawn element is fixed between a receiving disk, which is connected with a main spindle, and an interior compression lining, and the first drawn element is placed by one or several compression rollers against the interior compression lining while forming the rim shape and is calibrated in its wall thickness corresponding to desired rim requirements.
