ABSTRACT:
In the manufacture of a tire having a metal bead core, a covering structure (6) is associated with each bead core, which structure consists of a sheet (7) made of unvulcanized elastomeric material wrapped around the bead core and a strip of unvulcanized rubberized fabric (8), reinforced with heat-shrinkable material cords, wound around the elastomeric material sheet (7). The bead cores (3) are subsequently assembled with other tire components, and afterwards a tire vulcanization step is carried out. During this step the chemical bonding between the elastomeric sheet (7) and the bead core (3) is achieved, which bonding is promoted by the simultaneous shrinkage of the cords provided in the rubberized fabric strip (8).
