Abstract: A process for the manufacture of tire for high speed two-wheeled vehicles comprising making a cylindrical sleeve, attaching annular bead wires to the axial ends of said sleeve and shaping the sleeve into a toroidal configuration. A belt structure made of coils of cords is applied to the crown of said toroidal configuration. The belt is reinforced with HE cords which can be deformed to enable the tire carcass to be so largely expanded into the mold to achieve completely molding of a tread band.

Abstract: In a metallic mold, all or a part of the annular portion for molding at least the tread of the tire is formed by a plurality of small separate pieces that can be combined to form said annular portion. Between these small pieces, during the molding of the tire, clearances are maintained so as to permit the passage of air but not the passage of rubber. The above clearances are connected through vent holes to air suction means. Such vent holes are also connected with means for blowing pressure fluid through the clearances. The construction of this mold portion by means of small pieces made with cuts of the aforementioned portion in the axial and the circumferential direction permits regulation of the width of the clearances with respect to the rheometric characteristics of the elastomeric material to be molded and to adapt easily the mold to different tire sizes by increasing or decreasing the number of such pieces.

Abstract: A process for manufacturing elastomeric components of a tire for a vehicle wheel includes feeding a continuous elongated element from a delivery member by exerting a feeding pressure inside the delivery member, rotating a building support around a geometrical rotation axis of the support, carrying out controlled relative displacements between the delivery member and the support to form a tire component, stopping the feeding of the elongated element when formation of the tire component is complete, and exerting a counter-pressure inside the delivery member after stopping the feeding. Rotating the support assists circumferential distribution of the elongated element on the support. Carrying out controlled relative displacements assists transverse distribution of the elongated element on the support. The tire component is defined by a plurality of coils laid in a pre-established deposition pattern depending on a predetermined cross-section outline to be given to the tire component.

Abstract: A first carcass ply (3) is formed by depositing onto a toroidal support (11), strip-like lengths (13) cut to size from a continuous strip-like element and each comprising longitudinal thread-like elements (14) incorporated into a layer of elastomer material (17). The strip-like lengths are laid down sequentially in mutual circumferential side by side relationship, to form side portions (25) partly superposed on each other and crown portions (24) in mutual circumferential side by side relationship. Associated with the carcass ply (3) are annular structures (4) comprising a first and a second circumferentially inextensible annular inserts (27, 28) and an elastomer filling (29) interposed therebetween. A second carcass ply (31) is made in superposed position to the first carcass ply (3) and the annular structures (4). A belt structure (5), a tread band (8) and sidewalls (9) are combined with the carcass structure (2) thus formed, to define a tire (1) to be vulcanized.
