Abstract: A device for manufacturing a metal wheel (1) from a pre-form, with stretching rolls (3) engaging on the rim region of the pre-form, by means of which rolls a rim (1.1) is end-formed which, for forming a rim flange (1.7). Freely rotatable rolls (4) are arranged underneath the stretching rolls (3) and cooperate with them. A method for manufacturing a metal wheel (1) from a pre-form, the pre-form of the metal wheel (1) to be manufactured is placed on a clamping mandrel (2) and is caused to rotate, stretching rolls (3) engage an axially outer side of a rotation-symmetrical jacket of the pre-form with the exertion of radial pressure, and move along the jacket wall of the pre-form with compression and stretching of the jacket wall to form a rim (1.1) with a main movement component parallel with the axis of rotation (2.1) of the pre-form.

A method for manufacturing a metal wheel (1) from a pre-form, the pre-form of the metal wheel (1) to be manufactured is placed on a clamping mandrel (2) and is caused to rotate, stretching rolls (3) engage in the upper region of a rotation-symmetrical jacket of the pre-form with the exertion of radial pressure, and move along the jacket wall of the pre-form with compression and stretching of the jacket wall to form a rim (1.1) with a main movement component parallel with the axis of rotation (2.1) of the pre-form.
