Abstract
A film structure including at least a functional film, a carrier layer, and a counter-force liner, the functional film being in between the carrier layer and the counter-force liner. The carrier layer and the counter-force liner are larger than the receiving area, and the film structure includes a fastener adapted to fasten, directly or indirectly, the counter-force liner to the carrier layer at least on a portion of a zone outside the functional film. It is also proposed a corresponding machine, optical device and method for forming a functional film intended to be laminated on an optical article.
