ABSTRACT:
A process for the production of a plate with a polymer frame shaped onto the edge of the plate. The frame is extruded onto the plate while the latter is held stationary in a working station of a handling automaton or robot with a support device which corresponds to the shape of the plate in such a way that the edge of the plate projects freely over the support face of the support device. With the aid of the robot, an extrusion die having a through, mouth-like slot with two jaws engages the top and bottom surfaces of the circumferential edge of the plate as the mouth-like slot engages the plate edge. At the front end of the two jaws of the die mouth, there are sealing ledges movable at right angles to the plate surfaces, which are supported on the latter during the extrusion process.
