Abstract: 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 forming a functional film intended to be laminated on an optical article.

Abstract: Disclosed is a lamination machine including: a film support for receiving a functional film to be laminated; an article support configured to receive and position the optical article in a predetermined orientation; and an actuating member configured to move the film support and the article support toward each other for laminating at a predetermined pressure the functional film received in the film support onto the optical article received within the article support. The article support is a blocker support configured to receive a surfacing blocker onto which the optical article is to be disposed for lamination, the article support being further configured to transmit laminating forces induced by the predetermined pressure to the lamination machine during a lamination operation.
