Title (EN) FILM CLAMP
(FR) SERRE-FILM
Abstract:
(EN) A film clamp is disclosed which comprises a platen (3) having an aperture (5) in a flat working surface (9) of the platen (3). A proximal gripping member (11) is positioned to grip one edge of a film (1) supported on the platen (3), and a distal gripping member (13) is positioned to grip an opposite edge of the film (1). A bell crank (23) is adapted to press the proximal gripping member (11) into contact with a film (1) on the platen (3) and to press the distal gripping member (13) into contact with the film (1) and away from the proximal gripping member (11) to place the clamped film (1) in tension across the aperture (5). In order to provide a means for advancing the film (1) relative to the aperture (5) in the platen (3), a motor-driven endless belt (14) is mounted on the platen (3) adjacent the proximal gripping member (11), and the proximal gripping member (11) bears against the belt (14) to grip the film (1).
(FR) On décrit un serre-film comportant une plaque de base (3) dont la surface plate de travail (9) possède une ouverture (9). Un élément proximal de serrage (11) est disposé de manière à serrer l'un des côtés d'un film (1) maintenu sur la plaque de base (3), tandis qu'un élément distal de serrage (13) est disposé de manière à serrer un bord opposé du film (1). Un élément articulé (23) est adapté pour amener l'élément proximal de serrage (11) en contact avec un film (1) sur la plaque de travail (3) et pour amener l'élément distal de serrage (13) en contact avec le film (1) tout en l'écartant de l'élément proximal de serrage (11), ce qui fait que le film (1) ainsi serré est tensionné sur toute la largeur de l'ouverture (5). Un moyen permettant d'avancer le film (1) par rapport à l'ouverture (5) de la plaque de base (3) est prévu sous la forme d'une courroie sans fin (14) entraînée par un moteur et montée sur ladite plaque (3) à côté de l'élément proximal de serrage (11), et l'élément proximal de serrage (11) prend appui sur la courroie (14) pour serrer le film (1).
