Abstract

A process and an extrusion arrangement are suggested for cutting extruded hollow profiles while heated from the extruding process heat into the required lengths by means of a high-energy beam or jet moved along with the extruding operation. The interior of the extruded hollow profile is filled with a light-weight material at least at the cutting points. The light-weight material is advantageously an expansive foam mass, such as an aluminum foam or a plastic foam. The filling of the extruded hollow profile takes place either by coextrusion or by way of an arbor or a hollow-chamber bottom die of the extrusion arrangement.
