Title (EN) METHOD OF PRODUCING A LENS WITH AN EMBEDDED FOIL
(FR) PROCÉDÉ DE PRODUCTION D'UNE LENTILLE AVEC UNE FEUILLE INCORPORÉE
Abstract:
(EN) A method of producing a lens with an embedded foil, comprising the steps of positioning a foil (10) on a foil fixation holder, providing adhesive attachment dots (41) on the foil (10) on surface portions (12) opposite to the foil fixation holder, positioning the front mould (30) ensuring the contact of the attachment dots (41) with a surface (31) of the front mould (30), retracting the foil fixation holder and positioning a back mould (120) opposite to the front mould (30). Then the front mould (30) and the rear mould (120) are connected with a sealing bridging element (90) to build an assembly in order to form a mould cavity (45,155) with a pouring opening, wherein the edge (11) of the foil (10) is spaced apart (112) from the bridging element (90) and the assembly comprises passages between the attachment dots (141), the foil (10) and the front mould backside (31) allowing pouring a monomer into the entire mould cavity (45, 155) before curing the monomer and decomposing the assembly as well as cutting the lens with the embedded foil from the polymer block.
(FR) Cette invention concerne un procédé de production d'une lentille avec une feuille incorporée, comprenant les étapes consistant à : positionner une feuille (10) sur un support de fixation de feuille, fournir des points de fixation adhésifs (41) sur la feuille (10) sur des parties de surface (12) opposées au support de fixation de feuille, positionner un moule avant (30) en assurant le contact des points de fixation (41) avec une surface (31) du moule avant (30), rétracter le support de fixation de feuille et positionner un moule arrière (120) à l'opposé du moule avant (30). Ensuite, le moule avant (30) et le moule arrière (120) sont reliés à un élément de liaison d'étanchéité (90) pour construire un ensemble afin de former une cavité de moule (45, 155) avec une ouverture de versement, le bord (11) de la feuille (10) étant espacé (112) de l'élément de liaison (90), et l'ensemble comprenant des passages entre les points de fixation (141), la feuille (10) et la face arrière du moule avant (31) de sorte à permettre de verser un monomère dans la totalité de la cavité de moule (45, 155) avant le durcissement du monomère et la décomposition de l'ensemble ainsi que la découpe de la lentille avec la feuille incorporée à partir du bloc polymère.
