Abstract
【解決手段】 口金31の下側部材31bは油圧シリンダ34の油圧を変化させることで、その押し上げ量が変化する。コードCの移送速度が高い程、油圧シリンダ34の油圧を低くすることで、押し上げ量を少なくして通路33の上下の高さを高くし、口金31から押し出されるベルトの厚みを調整できる。コードCの移送速度を30m/min 程度に上げると共にベルトBの厚みが薄くならないように調整しても、口金31から押し出されるベルトBの表面のゴムの温度を110℃以内に保持できるので、ベルトの表面のゴムからブルームが発生する事態を防止できる。
【選択図】 図2
Description
請求項2に係る発明は、請求項1記載のゴム被覆ヘッドにおいて、前記口金の前記開口の付近は前記帯状体の厚み方向の両側に分割されており、前記寸法を変化させる手段は、前記分割されている一方を前記帯状体の厚み方向に変位させるものであることを特徴とするゴム被覆ヘッドである。
請求項3に係る発明は、請求項2記載のゴム被覆ヘッドにおいて、前記寸法を変化させる手段は、前記分割されている一方を前記帯状体の厚み方向に弾性変形させるものであることを特徴とするゴム被覆ヘッドである。
[第1の実施形態]
図1は本発明の第1の実施形態に係る押出機の斜視図であり、図2はその押出機におけるゴム被覆ヘッドのB−B断面図及び口金の開口部の寸法を変化させる装置のブロック図である。図1において、図5と同一の部分には図5で使用した符号を付した。ここで、本実施形態に係る押出機は、ゴム被覆ヘッド5以外は従来装置と同じである。
図4は本発明の第2の実施形態に係るゴム被覆ヘッドの図2に対応する構成を示す図である。この図において、図2と同一の構成要素には図2で使用した符号を付した。本実施形態に係るゴム被覆ヘッド6は、図2のゴム被覆ヘッド5における油圧シリンダ34に代えて電動シリンダを用いたものである。
Claims (3)
- 引き揃えられて移送されている複数本のコードをゴムで被覆し、該ゴムで被覆されたコードの厚みを規定する偏平な開口を有する口金から帯状体にして押し出すゴム被覆ヘッドであって、前記コードの移送速度に応じて前記開口の前記帯状体の厚み方向の寸法を変化させる手段を設けたことを特徴とするゴム被覆ヘッド。
- 請求項1記載のゴム被覆ヘッドにおいて、前記口金の前記開口の付近は前記帯状体の厚み方向の両側に分割されており、前記寸法を変化させる手段は、前記分割されている一方を前記帯状体の厚み方向に変位させるものであることを特徴とするゴム被覆ヘッド。
- 請求項2記載のゴム被覆ヘッドにおいて、前記寸法を変化させる手段は、前記分割されている一方を前記帯状体の厚み方向に弾性変形させるものであることを特徴とするゴム被覆ヘッド。
