Abstract
An apparatus for molding and curing a green tire includes a curing mold that includes a first sidewall plate and a second sidewall plate, with a ring of circumferential sectors circumscribing a mold cavity. The first sidewall plate is capable of coming into contact with a first annular fixing structure of the green tire when the green tire is inserted into the mold. The apparatus also includes at least a first bead molding ring movable from a first contracted operating position to a second extended operating position, a second bead molding ring movable from a first contracted operating position to a second extended operating position, and an expandable bladder delimited by a membrane associated for operation with the mold to exert a pre-molding pressure which is lower than a molding pressure to bring the first annular fixing structure into contact with the first sidewall plate.
