MANUFACTURING METHOD FOR PNEUMATIC TIRE

摘要

Provided is a method for manufacturing a pneumatic tire having an air permeation preventing layer of a cylindrical film of a thermoplastic resin or a thermoplastic elastomer composite. The method comprises shaping the cylindrical film, folding the film into a sheet shape, laminating rubber layers on the two sides, opening the laminate of those film and rubber layers into a cylindrical shape, and fitting the same on a tire shaping drum. When the rubber layers are laminated on the two sides of the folded film, the rubber layers are so deviated from each other in their widthwise positions that the end portion of one rubber layer is protruded from the end portion of the film, and that the end portion of the other rubber layer is arranged on the inner side in the widthwise direction than the protrusion of the end portion of the one rubber layer. In the state where the laminate is fitted on the tire shaping drum, the protruding end portion of one rubber layer covers the end portion of the other rubber layer. The adoption of the pneumatic tire manufacturing method makes it possible to reduce the troubles due to the splice portions of the rubber layers.
