    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a pneumatic tire which is highly durable and free from generation of cracks near the splice part, as a pneumatic tire in which an inner liner layer is formed using a laminate sheet.SOLUTION: A method for manufacturing a pneumatic tire includes a step in which a sheet 2 constituted of a thermoplastic resin or a thermoplastic resin composition obtained by blending a thermoplastic resin and an elastomer, and a laminate sheet 1 of predetermined length laminated with a rubber to be vulcanization bonded with the thermoplastic resin or the thermoplastic resin composition, are employed for lap splicing end part of the laminate sheet 1, and in this state, vulcanization molding of a tire is carried out. After the step, the method forms an inner liner layer 10 using the laminate sheet 1. Thus, the pneumatic tire can be manufactured. When cutting the sheet 2 composed of the thermoplastic resin composition obtained by blending at least the thermoplastic resin or the thermoplastic resin and the elastomer, to a predetermined length, a blade with a non sharp edge is used under temperature conditions at not less than 60°C and not more than the melting point of the thermoplastic resin.
    • 要解决的问题:提供一种制造充气轮胎的方法,所述充气轮胎是非常耐用的,并且在接合部附近不产生裂纹,作为使用层压片形成内衬层的充气轮胎。解决方案:一种方法 用于制造充气轮胎的步骤包括以下步骤:将由热塑性树脂构成的片材2或通过将热塑性树脂和弹性体共混而得到的热塑性树脂组合物和预定长度的叠层片材1与橡胶层压以进行硫化, 热塑性树脂或热塑性树脂组合物用于层压片材1的搭接端部,在该状态下进行轮胎的硫化成型。 在该步骤之后,该方法使用层叠片材1形成内衬层10.因此,可以制造充气轮胎。 将由热塑性树脂或热塑性树脂和弹性体共混而成的热塑性树脂组合物构成的片材2切割成规定的长度时,在不低于60°的温度条件下使用具有非锋利边缘的刀片 并且不大于热塑性树脂的熔点。

    • PROBLEM TO BE SOLVED: To provide a pneumatic tire having excellent durability in which the generation of a crack in a tie rubber layer that is caused in the vicinity of a splice part of a laminate sheet can be prevented after starting the use of the tire, in the pneumatic tire using, as an inner liner layer, a laminate sheet obtained by laminating a tie rubber layer and an air permeation preventing layer constituted of a thermoplastic elastomer composition that includes either a thermoplastic resin or the blend of a thermoplastic resin and an elastomer.SOLUTION: The pneumatic tire uses, as the inner liner layer, the laminate sheet obtained by laminating the tie rubber layer laminate and an air permeation preventing layer constituted of the thermoplastic elastomer composition that includes either the thermoplastic resin or the blend of a thermoplastic resin and an elastomer. In the pneumatic tire, a penetration part penetrating the air permeation preventing layer is formed in a range within 25 mm on both sides in the tire peripheral direction with the inner cavity side end A of the splice part of the air permeation preventing layer made as a center.
