Patent ID: 8609007

Claim:
A method of manufacturing pneumatic tyres, each tyre comprising a crown region extending between side regions axially spaced apart from each other and each carrying a respective bead at a radially internal position, the method comprising the steps of: building a green pneumatic tyre on a toroidal support having an outer forming surface of a conformation corresponding to the inner shape of the built tyre and provided with axially opposite side portions; and curing said tyre by the steps of: introducing the green tyre disposed on said toroidal support into a vulcanisation mould; closing the vulcanisation mould to compress the tyre side regions between said forming surface and the vulcanisation mould while forming a space between at least a portion of the vulcanisation mould and the crown region of the tyre; axially moving the side portions of the toroidal support apart from each other at the tyre side regions to cause an additional pressing of said side regions against the vulcanisation mould; and supplying heat to the tyre enclosed in the vulcanisation mould.
