Description
なおこの成型方法は、薄膜状フィルムインナーライナと未加硫ゴムシートとの幅が揃わない場合をも可とするものである。
なお、ここにおいてもまた、フィルムインナーライナの端部分どうしの直接的な接合は、そのインナーライナの、巻付け終端部分側の接着剤層上に、巻付け始端部分側を重ね合わせることによって行うことができる。
従ってここでは、フィルムインナーライナの端部分どうしの接合域と、隣接ゴムシートの端部分どうしの接合域とが、成型型の周方向に間隔をおいて位置することになる。
この一方で、未加硫隣接ゴムシートの接合域が20mmを越えると、重ね合わせ接合域でのゴムシート厚みが厚くなるため、製品タイヤのユニフォミティ、バランス等の低下が否めなくなり、また、薄膜状フィルムインナーライナの接合域が60mmを超えると、性能上は特に問題はないものの、不必要にフィルム材料を使用することになり、材料歩留りの低下、経済性の低下等が否めなくなる。
なお、フィルムインナーライナ1とゴムシート3との幅は揃わない場合もある。
すなわち、60mmを越えると貼損じたり精度が低下するおそれが高まることになる。

- ガスバリア性の薄膜状フィルムインナーライナと、未加硫隣接ゴムシートとを、該薄膜状フィルムインナーライナおよび該未加硫隣接ゴムシートのそれぞれの延在方向の各端縁位置を、該延在方向に相互にずらした状態で、接着剤層の介在下で貼着させてなる積層体の一本以上を、成型型の周りに、薄膜状フィルムインナーライナが内側となる姿勢で、成型型の全周にわたって巻付けるに当り、
端縁がその薄膜状フィルムインナーライナから突出して位置する未加硫隣接ゴムシートのその突出部分を、積層体の、成型型への巻付け始端部分の一部とし、その突出部分を成型型の表面に粘着させた状態で積層体の巻付けを開始し、
積層体の、成型型に対する巻付け終端部分を、同一のまたは、他の積層体の巻付け始端部分の内周側に入れ込んで、薄膜状フィルムインナーライナの端部分どうしを直接的に、重ね合わせもしくは突き合わせ接合させるとともに、未加硫隣接ゴムシートの端部分どうしを、薄膜状フィルムインナーライナの前記端部分どうしの接合域から成型型の周方向に間隔をおいた位置で直接的に、重ね合わせもしくは突き合わせ接合させる生タイヤの成型方法。 - 複数本の積層体を、成型型の周りに、それの全周にわたって巻付けるに当り、
一本の積層体の巻付け始端部分の一部としての前記突出部分を成型型の表面に直接的に粘着させる一方、他の積層体の巻付け始端部分の一部としての前記突出部分を、先に巻付けた積層体の巻付け終端部分を介して成型型の表面に間接的に粘着させて、
一本の積層体の巻付け終端部分の薄膜状フィルムインナーライナの端部分に対し、他の積層体の巻付け始端部分の薄膜状フィルムインナーライナの端部分を直接的に、重ね合わせもしくは突き合わせ接合させるとともに、一本の積層体の巻付け終端部分の未加硫隣接ゴムシートの端部分に対し、他の積層体の巻付け始端部分の未加硫隣接ゴムシートの端部分を、前記巻付け終端部分の薄膜状フィルムインナーライナの端部分と前記巻付け始端部分の薄膜状フィルムインナーライナの端部分との接合域から成型型の周方向に間隔をおいた位置で直接的に、重ね合わせもしくは突き合わせ接合させる請求項1に記載の生タイヤの成型方法。 - 未加硫隣接ゴムシートを、インナーライナ用ゴムシート、スキージゴム用ゴムシートもしくは、カーカスプライ用コードを埋設したゴムシートとする請求項1もしくは2に記載の生タイヤの成型方法。
- 同一の積層体内での、または、異なった積層体間での、未加硫ゴムシートの端部分どうしの重ね合わせもしくは突き合わせ接合域の、成型型の周方向の長さを0〜20mmの範囲とし、薄膜状フィルムインナーライナの端部分どうしの重ね合わせもしくは突き合わせ接合域の、成型型の周方向の長さを、0mmを越えて60mm以下の範囲とする請求項1〜3のいずれかに記載の生タイヤの成型方法。
