Claims (6)
- 筒状のシリンダと、このシリンダの内部空間に配置されるスクリューと、このシリンダの前端に設置されて前記内部空間と連通する押出流路を有するヘッドと、前記押出流路の前端位置で前記ヘッドに取り付けられて押出口を有する口金とを備えたゴム押出装置において、
前記ヘッドの前端面に沿って前記口金を前記ヘッドに対して相対的に少なくとも一軸方向に移動させる移動手段を有し、前記口金と前記ヘッドとを所望の相対位置で固定できる構成にしたことを特徴とするゴム押出装置。 - 前記一軸方向が前記押出口の延在方向に設定されている請求項1に記載のゴム押出装置。
- 前記移動手段により、前記ヘッドの前端面に沿って前記口金を前記ヘッドに対して相対的に任意の方向に移動可能な構成にした請求項1に記載のゴム押出装置。
- 前記移動手段の作動を制御することにより、前記口金と前記ヘッドとを所望の相対位置に移動させる制御部を有する請求項1〜3のいずれかに記載のゴム押出装置。
- 前記押出口から押し出されたゴム押出物の押出し方向に対する湾曲量を検知するセンサを有し、このセンサの検知データに基づいて前記制御部により前記口金と前記ヘッドとを所望の相対位置に移動させる構成にした請求項1〜4のいずれかに記載のゴム押出装置。
- 筒状のシリンダの内部空間にゴム材料を投入し、この内部空間に配置されたスクリューにより、前記ゴム材料を前方に押し出しつつ混合および混練した未加硫ゴムを、前記シリンダの前端に設置されたヘッドに形成されている押出流路に送り込み、前記押出流路の前端で前記ヘッドに取り付けられた口金に形成されている押出口から前記未加硫ゴムをゴム押出物として押し出すゴム押出物の製造方法において、
前記口金を前記ヘッドの前端面に沿って前記ヘッドに対して相対的に少なくとも一軸方向に移動させて前記口金と前記ヘッドとを所望の相対位置にして、前記未加硫ゴムを前記押出流路を通過させて前記押出口から押し出すことにより、前記ゴム押出物の押出し方向に対する湾曲量を小さくすることを特徴とするゴム押出物の製造方法。
