FIELD: tire industry; laying tread on casing of vulcanized pneumatic tire, both reused and new ones.
SUBSTANCE: proposed method includes placing the tread on pneumatic tire casing for molding the tread. Then, casing of pneumatic tire is mounted on rim and is inflated and circular elastic vulcanizing mold is placed on tread. Mold has inner circular surface for molding the tire tread. Then, two elastic flanges made in form of flexible members are placed between each bead and each peripheral edge of vulcanizing mold. Flanges cover outer surface of pneumatic tire formed by casing covered with tire tread and located between bead and edge of vulcanizing mold. System thus molded is placed in heating chamber where excessive pressure is maintained. Provision is made for device used for realization of this method.
EFFECT: simplified procedure, ease of laying tire on casing; enhanced reliability of vulcanizing mold subjected to high elastic action at vulcanization of tires.
