<p>A method of vulcanizing a green tyre having a toroidal structure is described, the method comprising: introducing a green tyre into a vulcanization mould; partially vulcanizing the green tyre so as to produce a semi-vulcanized tyre; removing the semi-vulcanized tyre (60) from said vulcanization mould; completing the vulcanization of the semi-vulcanized tyre outside said vulcanization mould. Moreover, the vulcanization completion action comprises: bringing at least one portion of said semi-vulcanized tyre to a temperature having a value of between about 75% and about 120% of the temperature of said at least one portion of semi-vulcanized tyre at the moment of its removal from the vulcanization mould, within a period of time of between about 2 minutes and about 7 minutes from the time at which said semi-vulcanized tyre was removed from said mould. The invention also relates to an apparatus for completing the vulcanization (3) of a semi-vulcanized tyre and to a vulcanization plant.</p> |
