发明名称 PROCEDE ET APPAREIL DE PRODUCTION D'UN MODELE POUR UNE OUVERTURE DE LENTILLE DANS UNE MONTURE DE LUNETTES
摘要 A method and apparatus for making a pattern from a blank in accordance with a set of coordinates defining a plurality of data points and collectively characterizing the size and shape of a lens opening in an eyeglass frame is presented. A controller includes an instruction set to control the operation of a router coupled to a carraige arranged for rectilinear movement toward and away from a work station and relative to the rotation of a blank fixtured at the work station whereby a pattern is cut with the desired size and shape. The apparatus further includes a sensor and light source in the feeding and staging area of the apparatus to advance a blank to a fixturing spindle located at the work station and to determine the nasal side orientation of the blank at the work station.
