<p>A green tyre (7) manufactured on a toroidal support (10) is closed in a vulcanization mould (2). Side portions (8) of the tyre are sandwiched between mould cheeks (4a, 4b) and the toroidal support (10). Steam or another fluid under pressure is fed to a diffusion interspace (19) formed, due to tyre expansion, between the inner surface of the tyre (7) and the outer surface (10a) of the toroidal support (10). A pre-cured liner is previously applied to the inner surface of the tyre (7), to prevent diffusion of water particles in the raw elastomer material.</p> |
