 EMI1.1 
 



   Es ist bekannt, Platten aus Faserstoffen und hydraulischen Bindemitteln mit Hilfe der   Papier-oder Pappenmaschine   in der Weise herzustellen, dass   der Faserstoff mit dem   
 EMI1.2 
 auf den Siebzylinder der   Pappenmaschine gebracht wird, um dort zu Platten \erarbeitet   zu werden. 



   Nach einem anderen bekannten Verfahren erfolgt   die Herstellung solcher Platten in   der Weise, dass der Faserstoff allein, im Holländer vorbereitet, auf dem Siebzylinder der 
 EMI1.3 
 Transportfilz aufgebracht und dort, etwa in einer Stanbkammer, mit Zement bestäubt wird
Das erstgenannte Verfahren hat den Nachteil, dass   der Zement dur t die gan/'t   
 EMI1.4 
 Verfahren der Überlstand zeigt, dass leicht eine blosse Schichtenbildung von Asbest und Zement-auf dem Transportfilze eintritt. 



   Gemäss der vorliegenden Erfindung sollen die genannten Übelstände dadurch vermieden werden, dass der Zement oder das sonstige Bindemittel ebenfalls   erst nach dr   Verarbeitung des Faserstoffes im Holländer zugeführt wird, dass aber die Aufstäubung des Zementes oder dgl. stattfindet, während der Faserstoff sich noch auf dem Siebzylinder oder dem Langsiebe der Pappenmaschine, also vor der Gautsche, beendet. 



   Hiebei   wird, da das Fasermaterial sielt   noch in lockerem, losem Zustande befindet.

 EMI1.1
 



   It is known to produce boards from fibrous materials and hydraulic binders with the aid of the paper or cardboard machine in such a way that the fibrous material with the
 EMI1.2
 is brought to the screen cylinder of the cardboard machine in order to be worked there into plates.



   According to another known method, such plates are produced in such a way that the fiber material alone, prepared in the Hollander, is placed on the screen cylinder
 EMI1.3
 Transport felt is applied and there, for example in a rod chamber, is dusted with cement
The first-mentioned method has the disadvantage that the cement thru the gan / 't
 EMI1.4
 The method of the supernatant shows that a mere layering of asbestos and cement easily occurs on the transport felt.



   According to the present invention, the above-mentioned inconveniences are to be avoided in that the cement or other binding agent is also only added after the processing of the pulp in the Hollander, but that the cement or the like is atomized while the pulp is still on the screen cylinder or the fourdrinier of the cardboard machine, i.e. before the couchette.



   This is because the fiber material is still in a loose, loose state.

PATENT-ANSPRUCH : Verfahren zur Herstellung von Platten auf Pappenmaschinen durch Aufstäuben von Zementpulver oder dgl. auf feuchten Faserstoff, dadurch gekennzeichnet, dass das staubförmige Bindemittel auf dn feuchten Faserstoff unmittelbar auf dem Siebzylinder oder dem Langsiebe, also vor der Gautsche, aufgestäubt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of panels on cardboard machines by dusting cement powder or the like on moist fiber, characterized in that the powdery binding agent is dusted on the moist fiber directly on the screen cylinder or the fourdrinier, i.e. before the couch. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
