Abstract
A tire vulcanizing device includes a vulcanization mold and a central part. The vulcanizing mold includes molding parts that defining a curing chamber therebetween. Inside the curing chamber is arranged a heating and ventilation apparatus structured for use with a heat-transfer fluid. The central part is structured to collaborate with the vulcanization mold by providing support to a heat-transfer fluid inlet and establishing communication between the heat-transfer fluid inlet and the curing chamber. The central part includes heating elements that are configured to be brought into operation before the heating and ventilation apparatus is brought into operation to cure a tire using the heat-transfer fluid.
