METHOD AND APPARATUS FOR MANUFACTURING A PNEUMATIC TYRE FOR VEHICLE WHEELS

摘要

Method and apparatus for manufacturing a tyre for vehicle wheels, said tyre (1) comprising a carcass structure having at least one carcass ply (2) operatively associated with a pair of annular reinforcing structures suitable for matching with a mounting rim, each annular reinforcing structure comprising at least one bead core (8) and one annular element (9), said at least one carcass ply (2) being turned up at least on one of said annular elements (9), said method comprising the steps of: feeding at least one semi-finished product onto a drum (20), placing at least one separating element (26) to a position radially external to said at least one semi-finished product, feeding said at least one carcass ply (2) to said drum (20) to a radially external position with respect to said at least one separating element (26), placing said annular element (9) to a position radially external to said carcass ply (2), turning up said carcass ply (2) around annular elements (9), removing said at least one separating element (26), applying said bead cores (8), applying a belt structure (7) to said carcass structure at a radially external position, applying a tread band (6) to said belt structure (7) at a radially external position, shaping said tyre (1) into a toroidal conformation, all the above steps being performed on said drum (20).
