Abstract
The subject matter of the present invention concerns presses for vulcanizing vehicle-wheel tires and in particular, those presses provided with a centripetal-type mold. For the purpose of optional heating of the sectors of the mold while avoiding heat-dispersion, heating-fluid losses, or any lowering of the temperature during the moving periods of the mold, there is provided, in the body of each sector, a network of channels that are connected, for example, through flexible tubing, to networks of the other adjacent sectors, in such a way as to realize a closed circuit with regard to the outside ambient, within which circuit the heating-fluid is permanently caused to circulate.
