摘要： A green tyre (50) disposed on a toroidal support (10) is introduced into a vulcanisation mould (102). The mould (102) is closed through axial approaching of a pair of sidewall plates (130a, 130b) acting against the sidewalls (51) of the tyre (50). Circumferential sectors (140) set to operate against the tyre tread band (52) are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre (50) against the toroidal support (10). Subsequently, said sectors are centripetally approached for penetration into the tread band (52) concurrently with a step of full moulding and vulcanisation of the tyre (50) carried out through admission of steam under pressure into the tyre itself.
