摘要 A reinforced tread belt (57) defined by two superimposed reinforced tread plies (55, 56) with oppositely-inclined reinforcing wires (37) is produced from a tubular annular element (44) formed, at least partially, by winding a wire (37) coated with elastomeric material about a rigid annular support (17) defined by a looped elongated plate having a curved outer surface (18), a curved inner surface (19), and two annular lateral edges (21); the tubular element (44) being cut along the edges (21) of the annular support (17) for producing the two reinforced tread plies (55, 56). <IMAGE> <IMAGE>
