FOLLOWER PILOTING METHOD FOR READING THE BEZEL OF A SPECTACLE FRAME

The method involves placing a follower (8) in contact against a bezel and following the bezel by sliding or rolling the follower along the bezel. An encoder motor pivots the follower around an axis and another encoder motor translates the follower along an axis parallel to the former axis. The motor...

Zusammenfassung:	The method involves placing a follower (8) in contact against a bezel and following the bezel by sliding or rolling the follower along the bezel. An encoder motor pivots the follower around an axis and another encoder motor translates the follower along an axis parallel to the former axis. The motors are utilized for exerting a transversal force and an axial force on the follower to create a global effort which varies, continuously or in steps, over the bezel contour reading according to the position of the follower along an axis of rotation normal to a general plane of rims of a frame (10).
