摘要：
A green tyre (2) is built on a forming drum (10a) to be then transferred to a bead moulding and pre- vulcanisation station (13) where each bead (6) of the tyre (2) is moulded by tightening it between two axially opposite clamping surfaces (15, 16) respectively carried by an axially external annular locating element (30) and an axially internal annular locating element (17) consisting of radially expandable circumferential sectors (24, 25) . The tightened beads (6) can be pre-vulcanised through heat supply by means of electric resistors integrated into the axially external annular locating elements (30) . The tyre (2) with the tightened and possibly pre-vulcanised beads (6) is transferred to a moulding cavity (44) having an inner wall substantially conforming to the shape of an outer surface (2b) of the moulded tyre (2) , to carry out moulding and complete vulcanisation of said tyre (2) .
