Abstract

Apparatus for shaping optical lenses, constituted by an articulated frames (1) and a movable frame (9) pivotally connected to said articulated frame (1).
Two axial pins (11, 20) which operate coaxially are provided at the lower end of the movable frame. A rubber tab (14) and a suction cup element (19) act at the inner end of said pins and bear against the outer surfaces of a lens for locking it. An appropriate template (26) retained between an actuating means (24) and a sleeve (25) rotates with the outer edge against a rotatable pin (29) connected to a movable arm (30) to produce an oscillation of the movable frame (9) so as to permit a continuous and constant contact of the peripheral edge of the lens with the peripheral edge of the grinding wheel (28) and generate a lens equal or proportional to the profile of the template used.
