Abstract

For producing an extrusion moulding device with which extruded profiles with superposed cover layers can be extruded in one work operation, a matrix is produced. The latter consists of two discs (2, 3), of which, initially, only the first disc (2) which receives the extrudate from a first extruder and shapes it to the exact dimensions of the cross-sectional profile to be produced, has to be processed. The second disc (3) serves only for the application of the cover layer from a second extruder. If appropriate, it can be provided, in addition to its recess (9) which shapes the cover layer, with an opening (8) of the same cross-sectional shape as the opening (7) in the first disc (2). This opening (8), however, can be produced by copying, so that the adaptation of the final cross-sectional shape is limited to the processing of the opening (7) in the first disc (2). Only the feed channels to the recess then have to be incorporated into the second disc (3). Since discs are relatively easy to process, the costs for producing the matrix are significantly reduced. <IMAGE>
