Claims (6)
- 熱可塑性樹脂または熱可塑性樹脂にエラストマーをブレンドした熱可塑性エラストマー組成物からなるフィルムの外周側に少なくともカーカス材を配置した円筒状体の幅方向両端部にビードリングを外嵌した1次成形体を成形し、この1次成形体を移送保持型の内周面に吸引保持した状態にして、複数の分割体から構成される円筒状の剛性内型を、この1次成形体に内挿した後、移送保持型による吸引を停止して1次成形体を剛性内型の外周面に移載し、次いで、この剛性内型上で前記カーカス材の幅方向両端部をターンナップするとともに、この1次成形体の外周面に他のタイヤ構成部材を積層してグリーンタイヤを成形し、このグリーンタイヤから剛性内型を取り外した後、グリーンタイヤを加硫装置に設置された加硫金型の内部に配置して、前記加硫金型を所定温度に加熱し、前記フィルムを内周側から与圧してインフレートさせつつ加熱してグリーンタイヤを加硫するとともに、このフィルムをタイヤ内周面に密着接合させることを特徴とする空気入りタイヤの製造方法。
- 膨張した際に前記グリーンタイヤの内周空洞部と同形状になるブラダーを、前記加硫金型の内部に配置したグリーンタイヤの内周空洞部で加熱流体によって膨張させることにより、前記フィルムを内周側から与圧してインフレートさせつつ加熱する請求項1に記載の空気入りタイヤの製造方法。
- 前記加硫金型の内部に配置したグリーンタイヤの内周面に加熱流体を直接注入することにより、前記フィルムを内周側から与圧してインフレートさせつつ加熱する請求項1に記載の空気入りタイヤの製造方法。
- 前記1次成形体を移送保持型の内周面に吸引保持する際に、1次成形体の外周側に移送保持型を配置し、1次成形体の内周側から与圧しつつ、移送保持型により1次成形体を外周側から吸引する請求項1〜3のいずれかに記載の空気入りタイヤの製造方法。
- 前記グリーンタイヤを加硫する際に、前記フィルムを内周側から0.01MPa〜3.0MPaの圧力で与圧してインフレートさせる請求項1〜4のいずれかに記載の空気入りタイヤの製造方法。
- 前記加硫金型の内部から外部に空気を吸引しつつ、加硫金型の内部に配置したグリーンタイヤを加硫する請求項1〜5のいずれかに記載の空気入りタイヤの製造方法。
