ABSTRACT:
A plastic lens shaper and finisher has a bed to which a first frame is mounted for reciprocation along the first axis. A second frame is mounted to the bed for reciprocation along the second axis generally transverse to the first axis. A third frame is secured to the bed adjacent said first and second frames. Displacement devices are operably connected to each of the first and second frames causing reciprocation thereof. A motor is mounted to the first frame and has a rotary cutter secured to the distal end thereof for cutting the blank. A second motor is mounted to the second frame and includes a first blank holding portion at one end and a first pattern holding portion at the other end. The second frame includes a portion carrying the second blank holding portion and a cylinder and piston assembly for driving the second portion for clamping and releasing the blank. A pattern engaging roller is mounted to the third frame for engaging the pattern as it rotates for thereby causing the second frame to be selectively moved on the second axis so that the blank is cut to a predetermined shape.
