Abstract
PURPOSE:To prevent the reduction of a crown upon retreading a tire and reduce working man-hours for the retreading, by a method wherein an annular elastic member is provided with a chord layer at the top thereof to restrain the elongation of the outer periphery of the elastic member. CONSTITUTION:An air bag 21 consists of an elastic member, whose principal constituent is rubber, and is provided with an annular elastic member 22, having a cavity 22a thereinside and a substantially circular section, and the layer 24 of plural chords, embedded into the outside top 22b thereof. The air bag 21 is fitted to the inside of a retreaded tire 31 while an enveloping coat 35, consisting of an elastic member, is arranged at the outside of the tire 31 so as to cover the same. The unvulcanized retreaded tire 31 is pressurized and heated in a vulcanizing pan from the outside of the enveloping coat 35 and the inside of cavity 22a of the air bag 21. Even when a pressurizing force P in the cavity 22a is much larger than the pressurizing force from the outside of the enveloping coat 34, the elongation of the outer periphery of the elastic member 22 may be restrained and the retreaded tire, having the objective radius of curvature of a crown, may be obtained, since the layer of chords 24 is embedded into the outside top 22b of the elastic body 22.
