Abstract

A process and device for carrying out the process allows for the extrustion of composite sections comprising a beam-like section made of a light metal and at least one insert made of another metal which provides a facing on at least one surface of the beam-like section. The beam-like section, which may be a conductor rail, is produced by extruding through a shape-giving die whereby at least two composite sections are produced simultaneously and the facing strips are positioned pairwise between opposite lying parts of the beam-like sections. The present invention allows the facing strips to be introduced into the extrusion device without the extreme bending previously experienced. Brittle materials which could not withstand the extreme bending experienced heretofore can now be used for facing material.
