Abstract: Method for renewing grinding wheel surfaces in a machine for grinding ophtalmic lenses, comprising one or more diamond wheels (2, 3, 4, 5), gripping means (7, 8) capable of receiving an ophtalmic lense, and control means. Once wheel wear is detected, the surface is renewed using an abrasive disk (9) fitted to the grinding machine in place of a lense in the gripping means. The invention also concerns a disk (9) for carrying out said method, with at least the peripheral surface consisting of abrasive material and having, at its centre, means for engagement with the machine's gripping means (7, 8). A machine for grinding ophtalmic lenses and carrying out said method is also described.

Abstract: The contour reading apparatus consists firstly of a supporting table (14) equipped with means for holding (16) capable of supporting the article whose contour is to be read, and secondly of a feeler (18) which is equipped with a rotatably mounted contact head (19) so that it can be applied against this article and which is conveyed on a carriage (20) itself mounted so that it can move relative to the supporting table (14). … The contact head (19) of the feeler (18) is rotated by being locked to a rotating drive, which is in practice the output shaft of a geared motor (26). … Application especially to the reading of the contour of circles or inner perimeters of a spectacle frame. … …
