Description
(1)前述の実施形態では、受入部132の断面を長方形状としたが、これに限定されない。例えば、図7Aのように、受入部132の断面を三角形状としてもよい。このとき、受入部132の断面形状は、吐出口131の形状と略同一である。ただし、吐出口131から吐出されたゴムストリップSは膨張するため、受入部132の断面形状は、吐出口131の形状よりも大きいほうが好ましい。受入部132の断面を三角形状とすることで、吐出口131の縁部131aにおけるゴム流れへの影響が少なく、ゴムストリップSの吐出時の形状変化を小さくすることができる。
2a 回転表面
11 押出機
13 口金
13a 端面
131 吐出口
132 受入部
S ゴムストリップ
R 成型ドラムの回転方向
Claims (4)
- ゴム材料を混練して送り出す押出機と、押出機の先端に取り付けられた口金と、口金の吐出口から吐出されたゴムストリップが巻き付けられる回転支持体と、を備える空気入りタイヤの成型装置であって、
前記口金は、前記回転支持体の回転表面に対向する端面であって前記吐出口よりも前記回転支持体の回転方向後方側に、前記回転支持体にすでに巻き付けられた前記ゴムストリップを受け入れ可能な受入部が形成されており、
前記受入部は、前記吐出口の縁部から前記回転方向後方側に向かって延びる凹部であることを特徴とする空気入りタイヤの成型装置。 - 前記受入部の断面は、前記ゴムストリップの断面より大きいことを特徴とする請求項1に記載の空気入りタイヤの成型装置。
- 前記受入部の断面は、前記ゴムストリップの最大厚み及び最大幅をそれぞれ短辺及び長辺とする長方形状であることを特徴とする請求項1又は2に記載の空気入りタイヤの成型装置。
- 押出機の先端に取り付けられた口金の吐出口から吐出されるゴムストリップを回転支持体に巻き付けて空気入りタイヤを成型する空気入りタイヤの成型方法であって、
巻き付け終了時、前記回転支持体の回転表面に対向する前記口金の端面を前記回転支持体に近付けるとともに、前記口金の端面であって前記吐出口よりも前記回転支持体の回転方向後方側に形成された受入部に、前記回転支持体にすでに巻き付けられたゴムストリップを受け入れることを特徴とする空気入りタイヤの成型方法。
