A process for the manufacture of multilayer sheet elements, of the type in which at least two different hot materials are plasticized, adopting the desired layered configuration by extrusion by means of an extrusion nozzle in the form of a sheet having edges equipped with peaks, said sheet having two main surfaces, so that the different materials have surfaces generally parallel to said main surfaces of the sheet characterized by proceeding to the extrusion of a composite sheet in which the edges provided with picks consist only of in one of the component plastic materials, proceeding then to the elimination of said protruding peaks of the sheet and proceeding to the new extrusion of most of the cut material.
