  • Method for vulcanising a tyre blank
    Patent number: 12128643
    Abstract: A method having the following steps is proposed: a) placing a green tire (20) to be vulcanized in a vulcanization mold, b) evaluating the temperature progression from the temperature sensor disposed in the cavity of the inner heater, wherein the energy input is adjusted both via the duration of the idle time and via the starting temperature, c) calculating an adjustment in the duration for the steam phase (24) of the inner heater when the idle time varies from a defined threshold, d) introducing steam into the inner heater of the vulcanization press and performing the steam phase (24, 25) for the calculated duration, wherein the adjustment of the duration for the steam phase (24, 25) is intended to ensure an optimal input of thermal energy for the vulcanization of the green tire (20), e) measuring the actual temperature progression with the temperature sensor (16) in the inner heater, f) comparing the actual temperature progression (27) with a target temperature progression (26) for a particular vehicle tire
