    Abstract: 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.

    Abstract: Building the carcass structure of tires for vehicle wheels includes associating, at each end edge of a carcass ply, at least one respective annular reinforcement structure formed by depositing along a circumferential direction a plurality of reinforcement elements having a first length. Such elements are cut to size from a reinforced continuous band-like element fed to a cutting group arranged at a first operative position adapted to allow a barycentric grip of the reinforcement elements. The cutting group can translate along a feeding direction of the band-like element to a second operative position for cutting to size a plurality of second reinforcement elements having a second length different from the first length. The second operative position is defined on the basis of the second length, so as to have a barycentric grip of the second reinforcement elements too.

    Abstract: A plurality of strip-like elements is applied onto a forming drum externally having a substantially cylindrical laying surface. The strip-like elements are disposed in mutually approached relationship to form at least one first annular reinforcing layer on the forming drum itself set to a first work diameter at which each of the applied strip-like elements on the laying surface subtends an arc of a circumference of a width as large as a submultiple integer of the overall circumferential extension of the laying surface itself. Adjustment devices operating on the forming drum subsequently carry out expansion of the latter to a second work diameter larger than the first work diameter, while maintaining its laying surface substantially cylindrical.
