    Abstract: Un procédé permet de coller sur une surface courbe d'un substrat un film fonctionnel (4) qui possède une forme initiale sensiblement plane. Pour cela, le film (4) est retenu sur une membrane déformable (1) par des moyens de liaison (2) qui permettent à des parties dudit film de glisser par rapport à la membrane lorsque ladite membrane est déformée. De cette façon, des contraintes qui sont créées dans le film par la déformation sont réduites. Le procédé est adapté pour appliquer un film fonctionnel sur une lentille ophtalmique.

    Abstract: A method of bonding a film (2) to a curved substrate (1) comprises preforming the film by applying a pneumatic pressure difference between two sides of the film and by heating said film. An intermediate shape is then conferred on the film, which is suitable for applying the film against a curved face of the substrate. This application is carried out, on the one hand, by keeping the film m the intermediate shape by means of an adjusted pressure difference applied between the two sides of the film and, on the other hand, by pressing the substrate against the film by means of a movable support (12-14). Such a method is used to obtain a defect-free ophthalmic lens with a film bonded to it.
