The machine includes a tire-building zone for producing, on a drum, a carcass entity that includes a carcass ply with carcass reinforcers. The machine also includes a finishing zone for producing a crown entity that includes a tread, a shaping system for causing the carcass entity to expand radially in order to give it a toroidal shape. In an assembling zone, the crown entity is assembled on the carcass entity. A biasing system interacts, during the shaping, with the carcass reinforcers so as to modify the angular orientation of the carcass reinforcers with respect to the circumferential direction of the drum. An automatic control unit allows a biased-crown tire to be manufactured in this way.

A method for making a vehicle tire wherein the vehicle tire includes a belt having at least one belt layer made of parallel steel cords embedded in rubber. The belt ply is built up on a building drum in order to produce a tire blank. Upon completion of the tire blank, the tire blank is shaped and vulcanized in a vulcanizing press. The method includes applying the belt ply made of parallel, extensible steel cords embedded in rubber to a building drum to build up the belt. After the tire blank is completed, the tire blank is shaped and vulcanized in a vulcanizing press to reduce the extensibility of the steel cords.

A first ply and then a second ply, which is superposed on the first ply, are produced on a hoop-type first support. The hoop-type first support has a first receiving surface, to form a laminate. The first and second plies forming the laminate are transferred onto an annular second receiving surface of a core so that the laminate is wrapped on the core until each ply is closed on itself and the laminate is thus closed on itself in a ring about the central axis of the core.

A pair of annular inserts of elastomeric material is circumferentially applied by spiraling around a laying surface of an auxiliary drum. Then a plurality of strip-like elements disposed in parallel side by side relationship with each other in the circumferential extension of the laying surface is applied onto the auxiliary drum, so as to form at least one first belt layer. Respectively opposite end portions of each strip-like element are radially superposed, each against one of the annular inserts, so that each of the annular inserts projects from a respective end edge of the strip-like element. The cap structure formed on the auxiliary drum is coupled to a carcass structure through toroidal conformation of the latter, in such a manner that the radially external ends of sidewall portions previously manufactured on the carcass plies are associated with the axially external ends of the annular inserts.

A method for manufacturing a tire involves successively performing steps that include: continuously converting a flat reinforcing strip into an undulating reinforcing strip; pressing peaks of waves of the undulating reinforcing strip one by one onto a surface of a tire blank that is driven in rotation by a drum about a drum axis; and winding the undulating reinforcing strip onto the tire blank. In the converting step, the flat reinforcing strip is converted into the undulating reinforcing strip in an immediate vicinity of the drum. The waves of the undulating reinforcing strip and movement of the peaks of the waves of the undulating reinforcing strip towards the surface of the tire blank extend in a plane substantially perpendicular to the drum axis.

A method in accordance with the present invention manufactures a tire with a biaxial monolayer belt component (MBC). The method comprises the steps of: winding a cord continuously about a first drum according to a pre-defined pattern to create a mesh of cords defining a single belt/overlay structure; adjusting the structure to a predetermined position on the first drum by laser lights; applying a tread component to the structure; transferring the structure and tread component to a second drum; applying the structure and tread component to a carcass component on the second drum; reducing pressure of the carcass component by a predetermined amount; and stitching the structure and tread component to the carcass component.
