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
