Beschreibung
Zusammenfassung:	An apparatus for deinking printed wastepapers in a system of separators through which printed wastepapers, previously impregnated with surface-active agents and alkalis, and repulped in the presence of an organic hydrocarbon compound and high-adsorptive flakes obtained by precipitating solutions of metal soaps of fatty or bituminous acids with solutions of salts of alkaline earths, are forced. The adsorptive flakes containing printing ink are separated from the repulped paper stock by latent vortex action.
