ABSTRACT:
A method of manufacture of a tire in which a carcass ply is formed by winding a continuous cord around a pair of spaced members to form a ply (31) having loops (36) at its edges. The cord ply is rubberized and support elements (32) (33) are located in the loops (36) to form a cylindrical ply having spaced hooped support elements at each ply edge. Bead wire assemblies (40) and (41) are located coaxially of the ply together with the support elements which are subsequently incorporated in the bead wire assemblies.
There is also provided a tire building former on which the above method can be performed. The former (100) comprises at least three coaxial discs (101), (102), (106) for supporting a carcass ply 30 on their radially outer surfaces. The central disc (106) is axially movable between the two other discs so as to support a portion of an elastomeric ply (103) helically wound onto the former (100) from a strip (104).
