METHOD FOR MANUFACTURING PNEUMATIC TIRE

摘要

The present invention provides a method of manufacturing a pneumatic tire which includes an inner liner layer formed of a laminated sheet obtained by laminating: a sheet made of a thermoplastic resin or a thermoplastic resin composition obtained by blending a thermoplastic resin and an elastomer; and rubber cured and adhered to the thermoplastic resin or the thermoplastic resin composition and in which no crack develops around a splice portion of the inner liner layer after the start of usage for running, the pneumatic tire thereby being excellent in durability. The method of manufacturing a pneumatic tire uses the laminated sheet having a predetermined length and the inner liner layer is formed from the laminated sheet through a step of cure-molding the tire with end portions of the laminated sheet lap-spliced. In the method, when at least the sheet made of the thermoplastic resin or the thermoplastic resin composition obtained by blending the thermoplastic resin and the elastomer is cut into the predetermined length, the cutting is performed by using an edge tool having a non-sharp edge under a temperature condition not lower than 60°C and not higher than a melting point of the thermoplastic resin.
