FIELD: production of pneumatic tires and repair of worn tire treads.
SUBSTANCE: the invention is pertinent to production of pneumatic tires and repair of worn tire treads and may be used at restoration of the worn treads of the pneumatic tires and also for molding of tire treads on the new pneumatic tires. The device for molding a tire tread on a carcass of a vulcanized pneumatic tire contains a carcass mounting hoop used for putting on the carcass of a raw tread cap. The device contains an elastic ring-type vulcanizing mold, the outer surface of which is covered with a flexible coupling and which is intended for molding a raw cap of a tread, and two elastic flanges for overlapping of the corresponding tire side strip produced by a molded case of a pneumatic tire covered by the vulcanizing mold. The elastic flanges are made in the form of discs with the peripheral edges of a bigger diameter and a smaller diameter. On the peripheral end of the bigger diameter there is a fixed rigid ring element used to provide a connection with a coupling. The device ensures required tightness at the molding and vulcanization of the tread and has a high wear-resistance.
EFFECT: the invention ensures required tightness at the molding and vulcanization of the tread and has a high wear-resistance.
