  • Mold and method for vulcanizing tires
    Patent number: 9731462
    Abstract: Tire vulcanizing mold able to cooperate with a curing press, said mold comprising two shells each one molding a sidewall of the tire and a ring of sectors for molding the tread of the tire, each sector comprising a support and a molding lining situated radially on the inside of the support, in which ring the sectors, when the mold is in the closed position, are all in circumferential contact one with the next via the molding linings and in radial contact on the shells via the front ends of the linings each of which forms a face for contact with the shell, said supports and linings being produced in such a way that each support is able to take up the clamping force applied to the lining coming into contact with the shell when the mold is in the closed position when said clamping force at said contact face exceeds a given threshold that is lower than the plastic threshold of the lining.
