Beschreibung
Zusammenfassung:	A process for the production of shaped, marbled thermoplastic products from themoplastic powder comprising heating a mixture of the thermoplastic powder, a plasticizer and a suitable coloring agent to an elevated temperature and thereafter mixing and cooling the smeary, liquid-like mass thereby produced until it changes into discrete sandlike flowable agglomerates, feeding at least two batches of differently colored agglomerates into an extruder via alternately controlled metering means and thereafter extruding the thermoplastic agglomerates from the extruder.
