Title: Method and apparatus for molding/curing tire for vehicle wheel
Inventor: CARETTA RENATO
IPC: B29C35/02
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for molding/curing a tire for a vehicle wheel which can obtain desirable effects for a final product stably by a method in which the inner end fringe in the circumferential direction of a tire is substantially disengaged from a ring-shaped support simultaneously with the inflation of the tire and made freely movable to/from the support by a controlled method. SOLUTION: An unvulcanized tire 7 produced on a ring-shaped support 10 is enclosed in a vulcanization casting mold 2. After the inflation of the tire 7, steam or another pressurized fluids is supplied to a diffusion cavity 18 formed between the inner surface of the tire 7 and the outer surface of the support 10. The inflation of the tire 7 is corrected by the separation of a bead 7b in the axial direction from the support 10. In this way, the generation of excessive tension by codes forming a tire carcass structure is prevented. The inner surface of the tire 7 is coated with a preliminarily cured liner in advance to prevent the diffusion of water particles in an unvulcanized elastomer.
