ABSTRACT:
An apparatus is disclosed for separating a replica from a matrix. The apparatus consists of a rotatable lower turntable and a movable upper turntable assembly between which the replica and matrix assembly to be separated are clamped during the separation process. A tool is provided to selectively apply pressure to the outer edge of the matrix to cause the seal between the replica and the matrix to be broken and also to provide a gap between the replica and the matrix. A pair of opposing clamp members having an aperture in the jaws of the clamps is inserted into the gap between the replica and the matrix. The clamp members are advanced so as to lock the matrix to the surface of the lower turntable. A pair of upper clamp members which are mounted on the support assembly for the upper turntable are moved into position so as to engage the replica. The upper turntable assembly with the replica clamped to the surface is then drawn vertically away from the lower turntable so as to cause a controlled separation of the replica in a direction normal to the recorded surface of the matrix, thereby preventing damage to the replica and the matrix. The clamps hold the replica and matrix until released and the parts are removed by the operator.
