Title
(EN) FILM-FORMING APPARATUS AND FILM-FORMING METHOD
(FR) APPAREIL DE FORMATION DE FILMS ET PROCÉDÉ DE FORMATION DE FILMS
Abstract
(EN)
A film-forming apparatus (100) and method capable of film lamination with superior evenness and good followability regardless of the size, shape and numer of articles being laminated. The film- forming apparatus (100) provided has a first chamber (10, 11) that is provided with a heating means (50, 51) and that is capable of maintaining a vacuum or a pressurized state, a second chamber (20, 21) that is disposed so as to be able to be joined to, and separated from, the first chamber (10, 11), that is provided with a movable supporting table (60, 61) on which an article (300, 310, 320) is supported and that is capable of maintaining a vacuum or a pressurized state, a frame-like film holding member (30, 31) that is disposed between the first chamber (10, 11) and the second chamber (20, 21) and that holds a film (200, 210), and an auxiliary film pressing tool (40, 41, 42) having a film pressing part (42a) that inhibits lifting of the film (200, 210) when the film is laminated on a surface of the article (300, 310, 320).
(FR)
L'invention concerne un appareil de formation de films (100) et un procédé capable de laminer des films avec une uniformité supérieure et une bonne capacité de suivi indépendamment de la taille, de la forme et du nombre d'articles laminés. L'appareil de formation de films (100) décrit comprend une première chambre (10, 11) qui est munie d'un moyen de chauffage (50, 51) et qui est capable de maintenir un vide ou un état sous pression, une seconde chambre (20, 21) qui est disposée de manière à pouvoir être reliée à et séparée de la première chambre (10, 11), qui est munie d'une table support mobile (60, 61) sur laquelle un article (300, 310, 320) est supporté et qui est capable de maintenir un vide ou un état sous pression, un élément de support du film de type cadre (30, 31) qui est disposé entre la première chambre (10, 11) et la seconde chambre (20, 21) et qui soutient un film (200, 210), et un outil de compression du film auxiliaire (40, 41, 42) comprenant une partie de compression du film (42a) qui empêche le soulèvement du film (200, 210) lorsque le film est laminé sur une surface de l'article (300, 310, 320).
