Patent number: 12290998Abstract: 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.Type: GrantFiled: July 13, 2021Date of Patent: May 6, 2025Assignees: Essilor International, Shamir Optical Industry Ltd.Inventor: Youval Katzman

Patent number: 10564067Abstract: An opaque adhesive can be used to secure the convex surface of a lens blank to a lens blocking piece. This opaque adhesive can include a resin that is curable under ultraviolet light and contains many dispersed pigment particles. The pigment particles may absorb light in the wavelength range of about 300 nm to about 800 nm such that the adhesive appears substantially opaque. A lens-on-block (LOB) system that uses the opaque adhesive to adhere a lens blank to a lens blocking piece facilitates on-block inspection of surface defects by increasing the contrast of light reflected from the surface being inspected. Put differently, the defects in the lens blank's surfaces stand out more when viewed in front of the opaque adhesive The inspection results can be used to carry out rework loops that eliminate or correct the detected defects, providing a streamlined method for on-block manufacturing of ophthalmic lenses.Type: GrantFiled: April 6, 2017Date of Patent: February 18, 2020Assignee: Shamir Optical Industry Ltd.Inventors: Guy Mechrez, Zohar Kadmon, Ofer Markman, Gil Perlberg, Haim Hainebach, Youval Katzman
