Zunächst werden die Stengel in kleine Stücke zerschnitten, wodurch die Marksubstanz innerhalb der Stengelschale blossgelegt wird. Die erhaltenen Stücke kommen dann in einen feststehenden oder rotierenden Kochkessel, welcher mit einer Lösung von Ätznatron oder dgl.

verarbeitung geeignete breiartige Beschaffenheit erlangt hat, wird das Wasser abgegossen und die Markzetten der Papiermaschine zugeführt, oder die so erhaltenen Markzellen gemeinsam mit dem faserigen Material in bekannter Weise weiter verarbeitet.
Eine zur Ausführung des Verfahrens geeignete Vorrichtung besteht aus einem Holländer A bekanntor Art, in welchem Waschtrommeln B und B'und zwischen denselben die Mosserwalzo lu angeordnet sind. Von den Waschtrommeln führen Rohre C und C' zu den Trügen D und D', in welchen die ans den Waschtrommeln kommende Masse sich absetzen kann. In dem Troge D befindet sich die Flüssigkeit mit den Markzellen, wie sie aus der Trommel kommt, während die festen Bestandteile im Trog D'bereits am Boden abgesetzt sind und darüber das reine Wasser steht. p und pi sind Rohre mit Hähnen zum Ablassen des reinen Wassers, welches sich über den abgesetzten Markzellen ansammelt.
Von den Trögen führt ein gemeinsames Rohr H zur Pumpe E, mittelst welcher durch das Rohr H und Rohr p"die Markzellenmasse der Papiermaschine F zugeführt wird.

and lime, then fibers are obtained which are suitable for producing a dense opaque paper. The pulp substance, however, when treated with the same substances, forms a translucent paper, which resembles parchment paper.
So far, the general view has been that there is a difference in Heschaffenleit

it is also possible, by means of a single cooking operation, to prepare the stem shell and pulp together for the paper production, in order to then use them together or individually to produce the desired paper.
First, the stalks are cut into small pieces, which exposes the pith substance inside the stem shell. The pieces obtained are then placed in a fixed or rotating cooking kettle, which is filled with a solution of caustic soda or the like.

Has reached a suitable pulp-like consistency for processing, the water is poured off and the pulp cells fed to the paper machine, or the pulp cells thus obtained are further processed together with the fibrous material in a known manner.
A device suitable for carrying out the method consists of a known type Hollander A in which washing drums B and B 'and between them the Mosserwalzo lu are arranged. From the washing drums pipes C and C 'lead to the chutes D and D', in which the mass coming to the washing drums can settle. In the trough D is the liquid with the marrow cells as it comes out of the drum, while the solid components in trough D 'are already deposited on the bottom and the pure water is above it. p and pi are pipes with taps to drain the pure water that collects over the detached marrow cells.
A common tube H leads from the troughs to the pump E, by means of which the pulp cell mass of the paper machine F is fed through the tube H and tube p ″.
