Abstract
A method for controlling a phase of molding an annular fixing structure of a green tire includes: introducing the green tire into a curing mold including an inflatable bladder; delimiting at least one portion of the annular fixing structure by using a first and a second surface opposed to each other; bringing the first surface and the second surface so as to bring a portion of the first surface and a portion of the second surface into contact with a corresponding radially inner and axially inner surface portion and a corresponding radially inner and axially outer surface portion, respectively, the annular fixing structure generating a first squeezing pressure; inflating the inflatable bladder of the curing mould so as to bring the first and the second surfaces closer together, thus generating a second squeezing pressure in such a way as to shape the radially inner and axially inner surface portions and the radially inner and axially outer surface portions of the annular fixing structure.
