Contour reading apparatus for spectacle frames, a corresponding sensor, and application of this device on the edge processing of lenses to be used

摘要

According to the invention, having a mobile probe (12) whose position can be identified in a given system of coordinates, this sensor (12) at the bottom of the bezel (10) whose cross-section is to be noted, by successively sighting by the head (15) of this sensor (12) at least two different points of at least one of the sides (13, 13 ′) of the bezel (10), and it is possible to deduce the coordinates of these points, the reading of the cross section of the bezel is used for the trimming operation of the glass is intended to be mounted in said groove (10).
