ABSTRACT:
A method of manufacturing a reinforced component of a motor vehicle tire carcass, in particular a body ply (2) and/or tread ply (3), whereby an elongated reinforcing element (5) is fed onto a substrate (7) along a generally sinusoidal path to form a reinforcing layer (29) defined by a succession of straight, substantially parallel portions (27) of the elongated reinforcing element (5) joined successively by curved end portions (28) thereof; the reinforcing layer (29) being moved substantially transversely in relation to the straight portions (27) to cooperate with an extrusion unit (34) which covers at least one surface of the reinforcing layer (29) with a covering layer (27,38)(37a,38a) of uncured elastomeric material.
