Patent number: 9162338Abstract: A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film.Type: GrantFiled: March 15, 2010Date of Patent: October 20, 2015Assignee: Essilor International (Compagnie Generale D'Optique)Inventors: Pascal Allione, Cedric Begon, Nicolas Lavillonniere, Agnes Ladous

Patent number: 8885251Abstract: The present invention relates to an apparatus for confirming a functionalized flexible planar film on an optical lens. The apparatus according to the invention may also be used in a process of functionalization of an optical lens. As a factor of the functionalization that one wishes to introduce into said optical lens and the nature of the functionalized flexible planar film used, the functionalization process is a process of gluing, transfer, or molding of a functionalized flexible planar film onto an optical lens. The implementation of each of these respective processes makes it possible to obtain a functionalized optical lens, said functionalization being adhered, transferred, or molded using a functionalized flexible planar film.Type: GrantFiled: July 20, 2011Date of Patent: November 11, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventor: Cédric Begon

Patent number: 8205551Abstract: The inventive method consists in transferring a pattern (P) onto the optical article (1) in the form of one or several portions of transferable material (3) retained by a pressure-sensitive adhesive material layer (2) and in applying transferable material portions with the aid of a pad by placing the adhesive material layer between the pad and a pattern receiving article. The use of the pressure-sensitive adhesive material makes it possible to use the different materials in the form of a transferable material. Said method is particularly suitable for producing patterns, in particular in the form of holograms on optical lenses, in particular ophthalmic lenses.Type: GrantFiled: December 6, 2006Date of Patent: June 26, 2012Assignee: Essilor International (Compagnie Generale d'optique)Inventors: Cédric Begon, Christelle Defranco
