This invention concerns a device used in the process of manufacturing an automobile pane equipped with a polymer frame placed on the edge of the pane The frame is extruded onto the pane which can be moved by means of a suitable support in such a way that the edge of the pane travels through a recess in an extrusion head and The recess of the extrusion head preferably includes a U-shaped jaw straddling the edge of the pane. At the front extremity of the two half-jaws of the U-shaped jaw there are disposed sealing ledges or shoes and which are movable perpendicularly to the surfaces of the pane and which, during extrusion, bear upon the surfaces of the pane. Alternatively, the extrusion head can include a fixed jaw where the sealing ledges or shoes slideably and sealingly contact the plate.

Device for extruding a polymer frame onto a plate-shaped object

This invention concerns a device used in the process of manufacturing an automobile pane 1 equipped with a polymer frame 52 placed on the edge of the pane 1. The frame 52 is extruded onto the pane 1 which can be moved by means of a suitable support in such a way that the edge of the pane travels through a recess in an extrusion head 25 and 40. The recess of the extrusion head 40 preferably includes a U-shaped jaw 41 straddling the edge of the pane. At the front extremity of the two half-jaws of the U-shaped jaw 41 there are disposed sealing ledges or shoes 42 and 43 which are movable perpendicularly to the surfaces of the pane and which, during extrusion, bear upon the surfaces of the pane. Alternatively, the extrusion head can include a fixed jaw where the sealing ledges or shoes slideably and sealingly contact the plate.

Process and device for shaping an extrudable plastic material

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.
