Description
好ましい構成例では、前記制御装置は、前記センサからの測定結果を受け取り、前記ウエブの幅方向の収縮率を求める演算部と、前記収縮率が設定範囲内であるか否かを判断する判断部と、前記収縮率が設定範囲外の場合に、前記乾燥装置の乾燥条件を変更する制御部とを有することを特徴としている。
好ましい構成例では、前記乾燥条件は、乾燥温度であることを特徴としている。
好ましい構成例では、前記乾燥温度は、前記ウエブが通過する前記乾燥装置内の乾燥炉内温度、又は前記乾燥炉内に供給する熱風温度であることを特徴としている。
好ましい構成例では、前記塗布工程にて、粘度が常に一定の燃焼抑制剤を前記ウエブに塗布することを特徴としている。
具体的には、検出器として、実際にウエブの幅を測定するセンサを用いる。
また、センサとしてCCD方式のレーザ透過型センサを用いることで、ウエブの幅を正確に測定することができる。
また、制御すべき乾燥温度を乾燥炉内温度又は熱風温度とすることで、簡単な方法で的確に所望の収縮率のウエブを得ることができる。
また、本発明に係る低延焼性ウエブの製造方法によれば、乾燥後のウエブの幅(収縮率)をフィードバックさせ、所定の収縮率となるように乾燥条件を適宜制御できる。したがって、将来的に安定した品質の巻紙を製造することができる。
ウエブWは走行経路2を走行する(図1参照)。このとき、ウエブWは巻出リールから巻き出され、巻取リールで巻取られるように延びている。塗布ユニット21は圧胴25及びグラビアローラ26を含んでいる。これら圧胴25及びグラビアローラ26は走行経路2、即ち、ウエブWを挟んで配置され、互いに逆向きに回転可能である。グラビアローラ26はその外周面に溝パターン(不図示)を有している。この溝パターンは、ウエブWの長手方向に対して一定間隔を存してウエブWの幅方向に横断するように複数箇所に燃焼抑制剤7が塗布されるように、グラビアローラ26の周方向に所定の間隔を存して配置されている。
製造機1の運転を開始すると、原反からウエブWが走行経路2を走行し、燃焼抑制剤7を塗布する前にウエブWの紙幅を測定する(ステップS1)。塗布装置3内にウエブWが入ると、第1のタンク18内の燃焼抑制剤7の容量が規定容量であるかが容量測定器22によって測定される(ステップS2)。規定容量である場合は、そのまま燃焼抑制剤7をウエブWに塗布する(ステップS3)。ウエブWは、連続的に燃焼抑制剤7が塗布され、走行経路2を走行する。ウエブWに燃焼抑制剤7を塗布することで、第1のタンク18内の燃焼抑制剤7の容量が減少してくる。したがって、第1のタンク18内の燃焼抑制剤7の容量は、規定容量以下となる。この容量を一定に保つため、燃焼抑制剤7を第2のタンク19から第1のタンク18へ供給する(ステップS4)。ウエブWに対する燃焼抑制剤7の塗布工程は、第1のタンク18内の燃焼抑制剤7の容量を確認しながら行われている。すなわち、ウエブWが塗布装置3内で塗布されている間、ステップS2~ステップS4までが繰り返されて実施されている。
)、乾燥工程を続行する。乾燥工程が続く間、すなわち未乾燥のウエブWがなくなるまで、ステップS6~ステップS9までの制御工程が繰り返される。
