摘要： Formation of a belt structure (2) takes place by laying down, directly on the carcass structure (3) of a tyre being processed (1), a laying layer (16) formed of a continuous strip-like element (16) of elastomer material directly coming from an extrusion die. The strip-like element (16a) has a differentiated thickness at its opposite edges to give rise to circumferential grip recesses (18) on the laying layer (16). Then, on the laying layer (16) a primary belt strip (6) is formed which is obtained by winding up of a continuous bare cord into coils (6a) disposed in axial side by side relationship. A cord of the high starting elongation type is preferably employed and it is wound up substantially in the absence of tensioning. A covering layer (19) made in the same manner as the laying layer (16) can be subsequently laid down on the primary belt strip (6).

摘要： The present invention concerns a process for manufacturing a tyre. Said process comprises the steps of: a) providing an elastomeric layer on an outer surface of a toroidal support; b) manufacturing said green tyre on said toroidal support; c) introducing said green tyre supported on said toroidal support into a moulding cavity; d) introducing a fluid under pressure into the space defined between the inner surface of the green tyre and the toroidal support; e) curing the green tyre. Said process further comprises the step of the step of causing an electrical current to flow in at least a heating element provided to the outer surface of said toroidal support so as to obtain an at least partial precuring of said elastomeric layer. The present invention further relates to a toroidal support (10) which is provided with at least a heating element (20) covering at least a portion of the outer surface of said toroidal support, said heating element comprising, in a radial direction from the inside towards the outside of said heating element, athermally insulating layer (22) and an electrically resistive circuit (23). Preferably, the heating element (20) further comprises a protective layer (24) radially external to the electrically resistive circuit (23).
