ABSTRACT:
A method and apparatus for applying a ribbon-like coating structure to the outer surface of a tire bead core. A bead core (2) is coaxially placed around a support drum (6) carrying an inflatable air bag (7) disposed in a deflated condition. Clasping sectors (14) circumferentially distributed in the drum are radially moved close to the inner surface of the bead core (2) to make a central portion of a ribbon-like coating structure (3) arranged about the inflatable air bag (7), adhere against the bead core itself. The air bag is inflated so as to form, on opposite axial sides relative to the bead core (2), two lobes (17, 18) each of them being enclosed between the outer surface of the drum (6) and a respective annular opposition bell (19, 20) coaxially encircling the drum. By axially moving the opposition bells (19, 20), a first and a second side flap of the coating structure (3) are applied to respective surfaces of the bead core (2). The second flap overlaps the first flap and is fastened thereto on the radially external surface of the bead core (2).
