摘要： 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. The tire blank is subsequently lowered and vulcanized.
