Abstract: A method for manufacturing elastomeric material components of a tyre for a vehicle wheel includes feeding a continuous elongated element from a delivery member for application onto a support, giving the support a rotary motion around a geometrical rotation axis of the support, so that the elongated element is circumferentially distributed on the support, and carrying out controlled relative displacements for transverse distribution between the support and the delivery member to form the elastomeric material components of the tyre with the elongated element. Feeding the elongated element takes place by extrusion of elastomeric material through at least one extrusion screw and at least one gear pump. The component is defined by a plurality of coils laid down in a pre-established deposition pattern depending on a cross-section outline to be given to the component. An apparatus for manufacturing elastomeric material components of a tyre for a vehicle wheel is also disclosed.

Abstract: A method of manufacturing a carcass structure for vehicle tires includes preparing strip sections, each comprising longitudinal and parallel thread elements coated at least partly with at least one layer of raw elastomer material. A first series of strip sections is laid down onto a toroidal support. First primary portions of annular reinforcing structures are applied against end flaps of the first series strip sections. At least one second series of strip sections is laid down onto the toroidal support. Together, the first and second series define a first carcass ply. A third series of strip sections is laid down onto the toroidal support. Second primary portions of the annular reinforcing structures are applied against end flaps of the third series strip sections. At least one fourth series of strip sections is laid down onto the toroidal support. Together, the third and fourth series define a second carcass ply.

Abstract: A green tire manufactured on a toroidal support is closed in a vulcanization mould. Steam or another fluid under pressure is infed to a diffusion gap which is formed, following an expansion of the tire, between the inner surface of the latter and the outer surface of the toroidal support. Tire expansion is compensated for, by axially moving the beads away from the toroidal support, thereby eliminating too strong tensions on the cords forming the tire carcass structure. A pre-cured liner is previously applied to the inner surface of the tire, to prevent diffusion of water particles in the raw elastomer material.
