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.

Abstract: An apparatus for vulcanizing a pneumatic vehicle tire, the beads of which, in a mounted state, are disposed on the radially inner periphery of a wheel rim. A tire blank, with the beads displaced laterally outwardly, is vulcanized using a heating press that is provided with two axially displaceable contour rings for forming the inner regions of the tire beads, and a heating bellows. To facilitate introduction of the tire blank and to protect the heating bellows, it is proposed, for loading the heating press, to axially move the contour rings together, into a position above a vulcanizing position, in such a way that the evacuated heating bellows moves downwardly through a space defined by the lower contour ring. The tire blank is subsequently placed over the contour rings, accompanied by a slight oval deformation of the lower tire bead, and is subsequently fixed on the contour rings by increasing the axial spacing therebetween. At the same time, the heating bellows passes into the interior of the blank.

Abstract: A method and apparatus for producing a green tire on a curving apparatus that includes a fixing head system having two rotatable and axially movable, one-piece bead-holding disks are provided. The bead-holding disks are swiveled about an axis perpendicular to their axis of rotation. The essentially cylindrical carcass member is disposed on the bead-holding disks concentric to their axis of rotation. The bead-holding disks are subsequently swiveled back into a position vertical to their axis of rotation. After the carcass is fixed on the disks, it is curved into a belt unit.

Abstract: A method and apparatus for checking the concentricity of a pneumatic vehicle tire that during operation has its bead regions mounted on the radially inner periphery of a wheel rim. The apparatus includes a two-part test rim, the sections of which are axially movable. In the region of the rim flanges, the test rim is provided with vulcanizing mold contours for receiving the bead-seating surfaces of a tire. The spaces between the tire sidewalls and the bead regions are provided with forming rings.
