Title
(EN) EDGE CUTTING-OFF DEVICE FOR OPTICAL FILM
(FR) DISPOSITIF DE DÉCOUPE DE BORD POUR FILM OPTIQUE
(JA) 光学フィルムの縁部切断分離装置
Abstract
(EN)
[Problem] To provide an edge cutting-off device for an optical film by which it is possible to stably convey an optical film body after cutting off unwanted edges, and by which it is additionally possible to increase the design flexibility of a path line. [Solution] The present invention is an edge cutting-off device for an optical film, the edge cutting-off device comprising: a cutting section that cuts off unwanted edges on both sides in the width direction of an elongated optical film to split the optical film into an optical film body and the unwanted edges; and a pair of nip rollers that are disposed downstream of the cutting section, and that sandwich both the optical film body and the unwanted edges. After the optical film body and the unwanted edges pass through the nip roller, the edge cutting-off device for an optical film separates the optical film body from the unwanted edges.

Le problème décrit par la présente invention est de fournir un dispositif de découpe de bord pour un film optique grâce auquel il est possible de transporter de manière stable un corps de film optique après découpe de bords non désirés, et grâce auquel il est en outre possible d'augmenter la flexibilité de conception d'une ligne de trajet. À cet effet, la présente invention porte sur un dispositif de découpe de bord pour un film optique, le dispositif de découpe de bord comprenant : une section de coupe qui coupe les bords non désirés des deux côtés dans la direction de la largeur d'un film optique allongé pour diviser le film optique en un corps de film optique et les bords non désirés ; et une paire de rouleaux pinceurs qui sont disposés en aval de la section de coupe, et qui prennent en sandwich à la fois le corps de film optique et les bords non désirés. Après que le corps de film optique et les bords non désirés passent à travers le rouleau pinceur, le dispositif de découpe de bord pour un film optique sépare le corps de film optique des bords non désirés.
