  • Method for vulcanizing a tire by predetermining its degree of vulcanization
    Patent number: 6478991
    Abstract: Method for vulcanizing a tire by predetermining a degree of vulcanization, comprising the steps of determining specified structural and dimensional parameters of the tire and of a vulcanization mould, determining the change over a time (t) of specified thermodynamic parameters of the tire, of the mould, of heat-supply fluids and of a cooling fluid, determining a parameter consisting of an equivalent vulcanization time t0, and determining an equivalent degree of vulcanization X(t0) at specified points within the tire by means of an equivalent isothermal rheometric curve at a reference temperature T0, comprising three consecutive sections having the following equations: X ⁡ ( t o ) = { k ⁢   ⁢ t o
