    摘要： A process for manufacturing tyres for vehicle wheels, comprising building, on a toroidal support (60), a carcass structure comprising at least one carcass ply associated, at axially opposite end edges thereof, with annular anchoring structures, the building step of the carcass structure comprises forming at least one reinforcing structure, operatively associated with the annular anchoring structures through deposition on the toroidal support (60) of at least one reinforcing element (5') along a predetermined curvilinear deposition path. The deposition of the at least one reinforcing element (5') comprises the steps of: cutting to size a piece (5) of at least one reinforcing continuous band-like element (4) fed by a feeding device (20) along a predetermined feeding direction (F), deforming the piece (5) obtained according to the curvature of a deposition part of the deposition path intended to receive said piece (5), and depositing the deformed piece at the deposition part. An apparatus (100) for carrying out such a process is also described.

    摘要： A green tyre (2) is either directly formed or, when building is over, engaged on an expandable toroidal support (23) to be then introduced into a vulcanisation mould (30) . The expandable toroidal support (23) comprises an expandable bladder (24) and a pair of pressure rings (28) each comprising first and second pressure sectors (29, 30) circumferentially distributed and operating at axially opposite positions on the expandable bladder (24) . Driving devices (31) act on the pressure rings (28) to selectively translate them between a work condition at which the pressure sectors (29, 30) of each pressure ring (28) , circumferentially aligned with each other, extend radially away from the geometric axis (X-X) , and a rest condition at which the pressure sectors (29, 30) are disposed close to the geometric axis (X-X) . Kinematic synchronisation members (32) operatively associated with the driving devices (31) mechanically mutually constrain the pressure rings (28), so as to impose a simultaneous and mutually symmetric movement on them.
