Abstract
The present technology provides a method of manufacturing a pneumatic tire. The method of manufacturing a pneumatic tire uses a laminated sheet having a predetermined length and an inner liner layer 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 thermoplastic resin or a 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.
Claims16
A method of manufacturing a pneumatic tire which uses a laminated sheet having a predetermined length and 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 an 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, the method characterized in that
- 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.
