  • Patent number: 10661485
    Abstract: A vulcanizing device for a tire includes a mold, a central part, a curing bladder, and an injector. The central part is positioned inside the mold and supports the curing bladder, which is arranged to press firmly against an internal part of a tire. An internal part of the curing bladder defines a vulcanizing chamber, which holds a pressurized heat-transfer fluid. The heat-transfer fluid, which is a mixture of steam and pressurized gas, circulates in the vulcanizing chamber and between an inlet pipe leading into the vulcanizing chamber and an outlet pipe leading out of the vulcanizing chamber. The injector is arranged outside the vulcanizing chamber and is connected to the inlet pipe, the outlet pipe, and a supply pipe for supplying steam or pressurized gas. The injector is structured to mix steam or pressurized gas coming from the supply pipe with the heat-transfer fluid leaving the vulcanizing chamber.

  • Patent number: 8500430
    Abstract: The invention relates to a vulcanizing press comprising two plates capable of adopting a proximal position in which said plates close a mold, so as to give a tire a predetermined shape, and a distal position in which the mold is open; and at least one bore formed in one of said plates called the support plate, the diameter of said bore being defined so as to let the head of a pin pass thereinto. The vulcanizing press further includes a locking/unlocking device comprising a first movable stop that can move between a rest position and an active position, in which said stop is interposed between the head of the pin and the support plate in order to keep said pin in the bore, the shank of said pin being fixed to the mold.
