本发明提供一种轮胎成型装置,能够抑制按压体夹入帘布反包气袋,不会引起生产效率的降低,能够提高帘布反包气袋的使用寿命。其具备压接单元,其将被定型鼓定型并且两端被卷起的外壳伸出部分压接并接合于环状的外壳主体部分。配置在搬入胎面环的一侧的压接单元具备按压体,其通过移动筒向轴心方向内侧移动借助帘布反包气袋将伸出部分压接于外壳主体部
The present invention provides a tire building apparatus capable of suppressing the entrapment of a pressing body into a turn-up / turn-over bag of the turn-up cord, and which can reduce the production efficiency and improve the service life of the turn-up turn-up bag. Which is provided with a pressure-bonding unit that is crimped and bonded to a ring-shaped case main body portion by press-fitting the case extension portion that is shaped by the setting drum and whose both ends are rolled up. The pressure-bonding unit disposed on the side where the tread ring is carried in includes a pressing body that is pressed inwardly in the axial center direction by a moving cylinder and presses the projecting portion to the case main body portion
