Abstract
A rolling device for work pieces with toothing, in particular gear wheels, includes first and second shaping tools which are guided by a guide relative to the work pieces. With respect to the work pieces, a first region of a tooth flank is shaped with the first shaping tool and a second region of the tooth flank is shaped by the second shaping tool. The first and second shaping tools are respectively mounted on first and second rollers. The second roller has an axial thickness on the circumference, which differs from the axial thickness of the first roller such that the second region of the tooth flank is different from the first region.
