Abstract
A process allows the production of composite sections made of at least two component parts such as conductor rails or the like having a beam-like section with a facing in the form of a conductive metal strip. The process makes use of an extrusion die whereby at least one of the components of the composite section is fed to the die by means of frictional force on a face which moves continuously towards the die.
