ABSTRACT:
An apparatus for deflashing a molded recorded disc includes a turntable support for the disc and a scissors type knife having a pair of blades pivotally mounted together with one of the blades being mounted on a support which is positioned adjacent the turntable so that a portion of the flash of the disc extends between the blades. A pneumatic cylinder has a piston rod connected to a knife support to selectively move with the support and the knife toward and away from the disc. The blades have cooperating cutting edges for cutting through the flash and one of the blades has a front end cutting surface for removing the flash when the disc is rotated by the turntable. In the operation of the apparatus the knife first removes a major portion of the flash and then the knife is moved slowly inwardly against the edge of the disc to remove additional portions of the flash until the desired diameter of the disc is reached.
