Abstract
The flash is removed from a freshly molded recorded disc by first bringing a knife against the edge of the disc and rotating the disc about its center to remove the major portion of the flash. A rotary cutter is then brought into contact with the edge of the rotating disc to remove the remaining portion of the flash. The rotary cutter provides the disc with a smooth edge and allows an accurate control of the diameter of the disc. The cutter is mounted on a pivotal bracket which is selectively moved toward and away from the disc by means of an air cylinder and piston which is connected to the bracket.
