ABSTRACT:
A method and apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operation. Two, respectively radially segmented, bead-forming rings that have a variable diameter and can be displaced axially are provided. For the purpose of vulcanizing the sealing surfaces disposed in the interior of the tire so that these surfaces will rest on the rim in an airtight manner, the bead-forming rings are introduced, in a radially retracted state, into the interior of the tire blank, whereby at least one of the tire beads is ovally deformed. The segments of the molding rings are subsequenty extended to an annular radial diameter whereby the molding surface portions of the molding rings can be moved axially outwardly over the tire beads without deforming the latter. The molding rings are then moved axially outwardly over the tire beads and then retracted to their smallest diameter, and are locked into position, whereupon the tire blank is vulcanized in a mold.
