Title (EN) FILM STRUCTURE, MACHINE, OPTICAL DEVICE AND METHOD FOR FORMING A FUNCTIONAL FILM INTENDED TO BE LAMINATED ON AN OPTICAL ARTICLE
(FR) STRUCTURE DE FILM, MACHINE, DISPOSITIF OPTIQUE ET PROCÉDÉ DE FORMATION D'UN FILM FONCTIONNEL DESTINÉ À ÊTRE STRATIFIÉ SUR UN ARTICLE OPTIQUE
Abstract:
(EN) A film structure comprising at least a functional film (212), a carrier layer (20), and a counter-force liner (22), said a functional film (212) being in between said carrier layer (20) and said counter-force liner (22). The carrier layer (20) and the counter-force liner (22) are larger than the receiving area, and the film structure comprises fastening means adapted to fasten, directly or indirectly, the counter-force liner (22) to the carrier layer (20) at least on a portion of a zone outside the functional film (212). It is also proposed a corresponding machine, optical device and method for form ing a functional film intended to be laminated on an optical article.
(FR) La présente invention concerne une structure de film comprenant au moins un film fonctionnel (212), une couche de support (20) et un revêtement de contre-force (22), ledit film fonctionnel (212) étant situé entre ladite couche de support (20) et ledit revêtement de contre-force (22). La couche de support (20) et le revêtement de contre-force (22) sont plus grands que la zone de réception et la structure de film comprend des moyens de fixation conçus pour fixer, directement ou indirectement, le revêtement de contre-force (22) sur la couche de support (20) au moins sur une partie d'une zone à l'extérieur du film fonctionnel (212). L'invention concerne également une machine, un dispositif optique et un procédé correspondants de formation d'un film fonctionnel destiné à être stratifié sur un article optique.
