Abstract: PROBLEM TO BE SOLVED: To provide a method to effectively read out the cross section of the groove edge of the edge section of a spectacle frame and a pointer to carry out this method. SOLUTION: In the method to read out the cross section of the groove edge 10 of the edge section 11 of a spectacle frame at least at one point above the edge section 11, with the position of a movable pointer 12 left capable of being defined using a specified coordinate system RT, the movable pointer 12 is moved following the groove edge 10. At least two different points on at least one side face 13 or 13' out of the side faces 13 and 13' of the groove edge 10 are visually confirmed in order to obtain the coordinate value of these points. The cross section of the groove edge 10 thus read out is used for trimming the lens to be secured in this groove edge 10.

Abstract: In a method for bevelling an ophthalmic lens, the lens is rotated about its own axis and is also displaced parallel to its axis as a function of its angle of rotation. Simultaneously, the edge of the lens is kept in contact with a grinding wheel. Thus the point of contact of the lens with the grinding wheel is constrained to follow a specific path. The specific path to be followed by the point of contact is an intermediate path selected between two paths resulting from a comparison between a collection of predetermined paths and two reference paths. The reference paths are each obtained from a plotting operation carried out prior to the bevelling operation on the ophthalmic lens using feelers. This method is used in grinding machines such that trimming and bevelling of ophthalmic lenses can be automatically performed.

Abstract: PCT No. PCT/FR93/00497 Sec. 371 Date Nov. 22, 1994 Sec. 102(e) Date Nov. 22, 1994 PCT Filed May 21, 1993 PCT Pub. No. WO93/24274 PCT Pub. Date Dec. 9, 1993Method for renewing grinding wheel surfaces in a machine for grinding ophthalmic lenses, comprising one or more diamond wheels (2,3,4,5), gripping members (7,8) capable of receiving an ophthalmic lens, and control. Once wheel wear is detected, the surface is renewed using an abrasive disk (9) fitted to the grinding machine in place of a lens in the gripping members. The invention also concerns a disk (9) for carrying out the method, with at least the peripheral surface consisting of abrasive material. A machine for gripping ophthalmic lenses and carrying out the 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. … …
