Abstract: A method and an apparatus for producing tread/reinforcement belt units for pneumatic vehicle tires in which a rotatable winding drum. a belt feeding device for a first and a second reinforcement belt layer, an overlay feeding device, a tread feeding device and a transfer device are provided. On a winding drum having double width and being axially movable, two tread/reinforcement belt units are simultaneously produced whereby in the first method steps the individual reinforcement belt layers are produced, subsequently two wound overlays are produced, and then two treads are applied one after another or simultaneously.
