Abstract: 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.

Abstract: A lens blocking/deblocking method/device to adhere an ophthalmic lens to a lens holding block A method for blocking an optical lens component (100) on holding unit (200) having bottom part (230) inserted and fixed in lens machining tool (400) and an upper part (250) having upper assembling surface (210) and external side parts (241). The method provides the optical lens component (100) with layer (320) of one-side adhesive tape arranged on bottom of component (100) to cover at least partially bottom (120); (S20) providing thermoplastic material on upper assembling surface (210). The thermoplastic material is heated where a part thereof flows under moderate pressure; (S30) placing the optical lens (100) with layer (320) on thermoplastic material when the thermoplastic is softened; (S40) applying pushing force (P1) on the optical lens (100), to spread the thermoplastic between layer (320) and upper assembling surface (210) and covers external side parts (241).
