(57) 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.
