Zusammenfassung:	A process for the preparation of thermosetting resin powder paints comprising the steps of extruding a melt of a resinous composition for a thermosetting powder paint, continuously cooling the composition and forming it into a sheet, and pulverizing the formed sheet. Air blasting nozzles are directed at the sheet while it is on the cooling rolls. The adherence between the sheet and the rolls is improved, and the air blasting nozzles provide an auxiliary means for cooling the sheet.
