Abstract: front page image
(EN) Provided is a method capable of continuously film-conveying without causing defects in an optical film such as folds, breaks, cracks or ruptures. The optical film conveyance method is a method that conveys an optical film along a conveyance path including a nip roll constituted by a pair of rolls 42. When the optical film passes between the pair of rolls 42, the pressure applied to the widthwise edge sections of the optical film is lower than the pressure applied to the widthwise central section of the optical film.
(FR) La présente invention concerne un procédé permettant de transporter un film de manière continue sans produire de défauts dans un film optique, tels que des plis, des cassures, des fissures ou des ruptures. Ledit procédé de transport de film optique est un procédé qui transporte un film optique le long d'un chemin de transport comprenant un rouleau pinceur constitué par une paire de rouleaux (42). Lorsque le film optique passe entre la paire de rouleaux (42), la pression appliquée sur les sections de bord dans le sens de la largeur du film optique est inférieure à la pression appliquée sur la section centrale dans le sens de la largeur du film optique.
(JA) 光学フィルムに折れ込み、割れ、亀裂、破断のような不具合を生じさせることなく連続的にフィルム搬送することができる方法を提供する。 光学フィルムの搬送方法は、一対のロール42で構成されるニップロールを含む搬送経路に沿って光学フィルムを搬送する方法である。光学フィルムが一対のロール42間を通過するときに、光学フィルムの幅方向端部にかかる圧力は、光学フィルムの幅方向中央部にかかる圧力よりも小さい。
