Abstract
The invention relates to various aspects in the production of extrusion products. The properties of extruded articles are dependent significantly, in addition to their formulation, also on the setting variables and in particular on the thus resulting process variables. The setting variables and in particular the process variables thus represent a state of the extrusion process characterized as 'fingerprint'. The thus claimed invention takes into account these facts and supports the operator of a production plant to detect earlier changes in quality and to systematically counteract a deterioration in the quality.
