Description
フィルムFの製造システム1の概略について説明する。
成形装置2は、熱可塑性樹脂が溶融した溶融樹脂を、シート状の基材Sに成形する(成形工程)。本実施形態では、成形装置は、押出成形装置である。
第1延伸装置4Aは、基材Sを、加熱した後、基材Sの流れ方向MDに延伸する。
塗工装置3は、成形工程によって成形された基材Sの第1面S1に、塗工液を塗布する(塗布工程)。塗工装置としては、例えば、バーコーター、グラビアコーター、キスコーターなどが挙げられる。なお、基材Sの第1面S1には、成形工程の後、塗布工程の前に、コロナ処理、プラズマ処理などの表面処理が、施されてもよい。
第2延伸装置4Bは、塗工液が塗布された前記基材を延伸する(延伸工程)。詳しくは、第2延伸装置4Bは、基材Sに塗布された塗工液を乾燥させる。これにより、塗工液が上記した被膜Cになる。また、第2延伸装置4Bは、被膜Cが形成された基材Sを、加熱した後、基材Sの幅方向TDに延伸する。幅方向TDは、流れ方向MDと直交する。延伸工程により、被膜Cが形成された基材Sが延伸され、上記したフィルムFが得られる。
スリット加工装置5は、フィルムFを、所定の幅に切断する。
ナーリング加工装置6は、所定の幅に切断されたフィルムFの幅方向両端に、ナールを形成する。ナールは、レーザーによって形成される。ナールは、加熱されたエンボスロールによって形成されてもよい。
巻取装置7は、ナールが形成されたフィルムFを巻き取る。
フィルムの製造システム1は、温度測定装置の一例としての赤外線サーモグラフィ装置8を、さらに備える。
(1)制御装置82は、未塗工部分P2の有無を、ソフトウェアによって判定してもよい。
