摘要: Disclosed is a method for manufacturing an optical lens including the following successive steps: a step of providing an optical lens attached to a blocking piece; a step of laminating a functional film on a surface of the optical lens; a step of obtaining an assembly constituted by the blocking piece, the optical lens and the functional laminated film; a step of cutting the excess film directly on the assembly, so as to reduce the film shape; and a step of deblocking the optical lens with the film, and the blocking piece.

摘要: 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.

摘要: A machine and method for obtaining a curved surface of a film structure that comprises a carrier layer and a functional film (212). The machine comprises an annular support member having a supporting face adapted for supporting the film structure, and an opening (10) that is covered by the film structure when said film structure is supported by the annular support member; a clamping system configured to clamp the annular support member and the film structure when supported by the annular support member; and a forming system configured to apply pressure, and preferably temperature, on the film structure so as to curve said film structure in or through the opening (10) of the annular support member. The opening (10) of the annular support member has a contour that is non-circular so that the obtained curvature of the functional film (212) corresponds to a target curvature.

摘要: This thermoforming machine includes a thermoforming chamber having at least one heated air inlet through which heated air flows into the thermoforming chamber at a controlled pressure. The air inlet cooperates with a heated air flow distribution regulator located in the thermoforming chamber and through which the heated air flows out of the thermoforming chamber at a predetermined temperature. The regulator includes a heated air flow regulating mask receiving heated air flow, having a plurality of flow restricting elements providing different air flow restrictions.

摘要: 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.
