<p>A process for the production of tyres is described, the process comprising the steps of - building a green tyre (50) including a carcass structure (52) comprising at least one carcass ply operatively associated with a pair of annular anchoring structures (51a, 51b), a tread band (53) in a radially outer position to said carcass structure, and a belt structure interposed between the carcass structure and the tread band; - moulding and vulcanising the green tyre (50) within a vulcanising mould (200), the mould including an upper sidewall plate (21 ) and a lower sidewall plate (20) and a ring of circumferential sectors (55) circumscribing a moulding cavity (17); wherein between the building step and the moulding and vulcanising step are further provided the steps of: pressing at least a portion of an axially inner surface (71a, 71b) of at least one of the annular anchoring structures (51a, 51b), so as to configure, by means of a first locating surface (5a, 5b), a portion of axially outer surface (7a, 7b) of at least one of the pair of annular anchoring structures (51a, 51b) so as to be substantially complementary to a portion of supporting surface (31 a, 31 b) of the upper or lower sidewall plate (20, 21 ) of the mould (200) containing the green tyre during the moulding and vulcanising step; supplying heat to the green tyre (50). The invention further relates to an apparatus (100, 100') for the production of tyres and to a moulding and vulcanising station (110) including that apparatus.</p> |
