Title
(EN) AUTOMATIC OR SEMI-AUTOMATIC DEVICE FOR TRIMMING AN OPHTHALMIC LENS
(FR) DISPOSITIF AUTOMATIQUE OU SEMI-AUTOMATIQUE POUR LE DETOURAGE DU PROFIL EXTERIEUR D'UN VERRE OPHTALMIQUE
Abstract
(EN) The invention concerns a device comprising in combination: means for detecting (4) characteristics of a lens; means for integrating characteristics representing a patient's morphology; a support (3) of the mobile lens along a predetermined trajectory between a first measuring position and a loading position; grinding means (20); and means forming a gripping and clamping clip (25) for transporting the lens from said loading position to said grinding position.
(FR) Le dispositif comprend en combinaison: des moyens de détection (4) de caractéristiques d'un verre; des moyens pour prendre en compte les caractéristiques représentatives de la morphologie du patient; un support (3) du verre mobile selon un trajet prédéterminé entre une position de mesure et une position de chargement; des moyens de meulage (20) et; des moyens formant pince de préhension et de serrage (25) pour transporter le verre de ladite position de chargement jusqu'aux moyens de meulage.
