KAISERLICHESIMPERIAL

PATENTAMTAfPATENT OFFICE f

Zur Herstellung der den Gegenstand vorliegender Erfindung bildenden Filtrir- und Aufsaugmasse aus Kieselguhr in Papierform kommen reine baumwollene Lumpen ohne Fäden, Nähte, Knoten und dergl. in Verwendung. For the production of the subject matter of the present invention Filtrir- and Absorbent material made of kieselguhr in paper form are pure cotton rags without threads, seams, knots and the like. Use.

Diese Lumpen werden in kleine Stückchen geschnitten und durch entsprechende Vorrichtungen vollkommen von Staub befreit.These rags are cut into small pieces and put through appropriate devices completely freed from dust.

Die so zerkleinerten und gereinigten Lumpen werden nun im Holländer unter Wasserzufiufs vollkommen fein zerrissen und zerfasert, bis zu einer Faserlänge von circa 40 mm.The rags, chopped up and cleaned in this way, are now under water in the Hollander completely finely torn and frayed, up to a fiber length of approx. 40 mm.

Hierauf wird der so vorbereiteten Fasermasse gebrannte oder ungebrannte, geschlämmte oder nicht geschlämmte gepulverte Kieselguhr zugesetzt und das Ganze nochmals im Holländer gemahlen und somit innig vermengt.The fiber mass prepared in this way is then burned or unfired, slurried or Not slurried, powdered kieselguhr added and the whole thing again in the Hollander ground and thus intimately mixed.

Das Gemenge kann dann auf bekannte Art weiter zu Papier oder papierartiger Masse verarbeitet werden.The mixture can then be further processed into paper or paper-like mass in a known manner will.
