Abstract

A device for manufacturing a laminated semifinished material by indirect extrusion of a sintered-bond blank consisting of layers of metal, metal alloys, metal mixtures or mixtures of metals and nonmetals comprises a vessel with a rectangular cutout or extrusion chamber and a one- or multipart extrusion die with one or several cutouts. A surface of the die facing the blank is profiled in the form of one or more roof gables, the surfaces of which gable forms extend perpendicularly towards the cutout from a sliding surface of the extrusion die.
