Zusammenfassung:	Thermoplastic foam is converts into useful products by simultaneously compressing and agitating particles of the foam. The particles are formed into a substantially unitary mass of hot softened material which can be immediately formed, cast or extruded into useful particles. The apparatus comprises a ram (25) operating in cylinder (16) and driving particles of thermoplastic (preferably foamed polystyrene or polyethylene) against a rotating wheel at (19).
