Abstract

L'invention concerne un procédé et un dispositif pour retirer un film, en particulier un film de protection (4), qui adhère par adhésion et/ou charge électrostatique sur une surface substantiellement plane d'un support en forme de plaque ou sur un film de base plan et flexible (1). À l'aide d'un élément d'appui (8) pouvant se déplacer dans le sens de la hauteur et doté d'une couche adhésive ou d'un ruban autoadhésif (9), le film de protection est soulevé du support ou du film de base. Le support en forme de plaque ou le film de base ou encore l'agencement composé de plusieurs couches de film, découpé dans une certaine taille pour la suite du traitement, est maintenu au moins dans la partie antérieure sur une table d'appui à l'aide d'un aspirateur à vide (3). Après le soulèvement du film de protection, celui-ci est saisi sur l'arrière par un organe de préhension monté sur un dispositif de traction pouvant se déplacer par rapport à la table d'appui et appuyé contre un contre-appui (6) placé sur le dispositif de traction, puis retiré par un déplacement du dispositif de traction et aspiré par un dispositif d'aspiration.
