充气轮胎的制造方法
摘要：
本发明提供一种充气轮胎的制造方法，能够提高刚性型芯的拆卸性。该方法通过型芯成形法来制造充气轮胎（1）。在该制造方法中包括：在刚性型芯（10）的外表面（18）粘贴轮胎部件而形成生胎（1L）的生胎形成工序（S1）；对生胎（1L）进行硫化的硫化工序（S2）；从已硫化后的轮胎（1）拆卸刚性型芯（10）的刚性型芯拆卸工序（S3）。生胎形成工序（S1）包括内衬形成工序（S11），在刚性型芯（10）的外表面（18）中的至少一对胎圈成形面（18c、18c），分别使带状的橡胶条带（24）的侧缘（24t）相互重叠、且将橡胶条带（24）从轮胎径向外侧朝向内侧粘贴成螺旋状，由此形成内衬（9）的胎圈部侧区域（9c）。
摘要（英）：

The present invention provides a manufacturing method of a pneumatic tire, which may improve the removal nature of a rigidity core. The manufacturing method of the pneumatic tire makes the pneumatic tire by means of a core shaping method. The manufacturing method includes: in the raw tyre shaping process (S1), pasting tyre units on the outside surface (18) of rigidity mold core (10) to generate raw tyre (1L). In the vulcanization process (S2), performing vulcanization on the raw tyre (1L). In the dismounting rigidity mold core process (S3), it dismounts rigidity mold core (10) from the vulcanized tyre (1). The raw tyre shaping process (S1) includes lining shaping process (S11), shaping a least one pair of tire bead (18c) from the outside surface (18) of the rigidity mold core (10), making overlapping between the lateral margins (24t) of zonal rubber stripe (24) and pasting the zonal rubber stripe (24) from outside tyre to inner tyre as heliciform shaping. Therefore, it forms the side area (9c) of lining (9).
