Papierstoffhoiiänder m ! t ebenem Trog und hohem Bodengef lle,
Die in der Papierfabrikation gebräuchlichen Holländer waren ursprünglich so eingerichtet, dass die verlängerte Welle der Holländerwalze über der Oberkante des Seitenkanales lag. Als dann später das Bodengefälle der Holländer vergrössert wurde, wurde die Welle der Holländermahlwalze quer durch den Seitenkanal hindurchgeftlhrt, der zu diesem Zwecke mit Stopfbüchsen versehen werden musste. Diese Einrichtung hat den Übelstand, dass der Stoff durch Öl, das durch die Stopfbüchsen hindurchdringt, verunreinigt werden kann ; ausserdem wird auch durch die durch den Seitenkanal führende Welle die Umlaufgeschwindigkeit des Stoffes gehemmt.
Um diese Übetständo zu vermeiden, wird nach der Erfindung die Welle der Mahlwalze so angeordnet, dass sie unter dem Boden des Seitenkanals durchgeführt ist.
Ein derartiger Holländer ist in Fig. 1 im senkrechten Längsschnitt, in Fig. 2 im senkrechten Querschnitt und in Fig. 3 in Oberansicht dargestellt.
Die Messerwalze a ist in dem Holländer so tief angeordnet, dass die verlängerte Welle b der Mahlwalze a unter dem Boden c des Seitenkanals liegt. Auf diese Weise wird ein ganz freier, offener, leicht zu reinigender Trog mit sehr hohem Bodengefälle erhalten, ohne dass besondere Dichtungen für die Lagerung der Mahlwalze notwendig werden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Papierstoffhoiiänder m! t level trough and high floor slope,
The Dutchman used in paper manufacture was originally set up in such a way that the elongated shaft of the Dutchman roller lay over the upper edge of the side channel. When the floor slope of the Dutchman was increased later, the shaft of the Dutchman grinding roller was led through the side channel, which had to be provided with stuffing boxes for this purpose. This device has the disadvantage that the substance can be contaminated by oil that penetrates through the stuffing boxes; In addition, the speed of circulation of the material is also inhibited by the wave leading through the side channel.
In order to avoid this exercise, according to the invention the shaft of the grinding roller is arranged so that it is passed under the bottom of the side channel.
Such a Hollander is shown in Fig. 1 in vertical longitudinal section, in Fig. 2 in vertical cross section and in Fig. 3 in top view.
The knife roller a is arranged so deep in the Hollander that the elongated shaft b of the grinding roller a lies under the bottom c of the side channel. In this way, a completely free, open, easy-to-clean trough with a very high floor slope is obtained without the need for special seals for mounting the grinding roller.
