Title
(EN) DEVICE FOR GUIDING A FLEXIBLE FILM BACKFOLDED ON ITSELF
(FR) DISPOSITIF DE GUIDAGE D'UN FILM SOUPLE REPLIE SUR LUI-MEME
Abstract
(EN) The device comprises a smooth bearing plate (4) secured to a frame (5) and mounted in parallel to the film (1) and arranged to be engaged between two folds (, 3) of the film, and pressure wheels (6) biased towards the bearing plate (4) by means of springs (10) in order to maintain the film folds against the bearing plate (4), the pressure wheels (6) being mounted on wheel supports (8) so mounted as to have different orientations with respect to the displacement direction of the film (1). Application particularly to the making of perfusion bags.
(FR) Le dispositif comprend une plaque d'appui lisse (4) fixée à un châssis (5), montée parallèlement au film (1) et disposée pour s'engager entre deux plis (2, 3) du film, et des roulettes de pression (6) rappelées vers la plaque d'appui (4) par des ressorts (10) pour maintenir les plis du film contre la plaque d'appui (4), les roulettes de pression (6) étant montées sur des supports de roulettes (8) montés pour prendre différentes orientations par rapport à la direction de déplacement du film (1). Application notamment à la réalisation de poches de perfusion.
