摘要： A green tyre disposed on a toroidal support is introduced into a vulcanisation mould. The mould is closed through axial approaching of a pair of sidewall plates acting against the sidewalls of the tyre. Circumferential sectors set to operate against the tyre tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre against the toroidal support. Subsequently, the sectors are centripetally approached for penetration into the tread band concurrently with a step of full moulding and vulcanisation of the tyre carried out through admission of steam under pressure into the tyre itself.

摘要： A method of moulding and curing tyres for vehicle wheels includes the steps of disposing a tyre being processed on a toroidal support, enclosing the tyre and the toroidal support inside a moulding cavity defined in a vulcanization mould, pressing the outer surface of the tyre against the moulding cavity walls, and administering heat to the tyre to cause molecular crosslinking of the tyre. The pressing step includes the steps of compressing side portions of the tyre between the moulding cavity walls and the outer surface of the toroidal support, concurrently with the closing step, and imposing an expansion to a radially-outer portion of the tyre to bring the radially-outer portion of the tyre against the walls of the moulding cavity.

摘要： A process for manufacturing, moulding, and curing a tire includes the steps of manufacturing a tire comprising a first elastomer material, providing an inner surface of the tire with a treatment to prevent permeation of a fluid under pressure through the treatment, closing the tire into a moulding cavity defined in a vulcanization mould, admitting a fluid under pressure into a space defined by the treatment in order to press an outer surface of the tire against the at least one wall of the moulding cavity, and applying heat to the tire to vulcanize the first elastomer material. A shape of the at least one wall of the moulding cavity matches a shape of the outer surface of the tire after vulcanization is complete. The treatment includes at least one layer of a second elastomer material having a sulfur-curable polymeric base and a vulcanizing system dissolved in an organic solvent.

摘要： An apparatus for forming curing envelopes which apparatus enables the use of a conventional inner tube mold for making a curing envelope preform in the form of an envelope tube which may have a portion thereof easily removed to provide a curing envelope suitable for use in a tire retreading process. A curing envelope is made by placing an annular tube of uncured envelope material in a curing mold having a center core and a mold insert installed therein. The insert includes a pair of coaxial annular rings projecting radially outwardly from the center core and connecting straps for maintaining the axial spacing between the rings. The mold is closed and heat and internal pressure are applied to the envelope tube for curing the envelope tube and urging the tube against the interior cavity surface with the annular rings penetrating into the inner wall of the tube for forming therein corresponding annular grooves. The mold is then opened and the envelope tube is removed from the mold after which the envelope tube is severed along the annular grooves to remove the portion of the inner wall of the envelope tube between the grooves thereby to form a curing envelope of generally U-shape cross-section.
