PATENTAMT.PATENT OFFICE.
Bei der Herstellung von Pappe wurden bisher die Tafeln dadurch entwässert, daß sie zwischen Eisenplatten und Filzen einem hydraulischen Druck ausgeset2t oder zwischen Walzen ausgepreßt wurden. Eine zufriedenstellende Wirkung konnte mit diesem Verfahren nicht erreicht werden, da das ausgepreßte Wasser nicht genügend abfließen kann. Bei der Anwendung gelochter Behälter oder ίο Eisenplatten drückt sich das Gut in die Löcher und wird beschädigt. Diese Übelstände sollen nach dem. neuen Verfahren dadurch vermieden werden, daß die Pappen zwischen gelochte, mit engmaschiger Gaze oder ähnlichem Stoff bedeckte Tafeln aus Eisen oder ähnlichem Material gelegt und nun das Ganze durch gelochte Walzen' geführt und ausgepreßt wird.In the manufacture of cardboard, the boards have so far been drained by the fact that they exposed to hydraulic pressure between iron plates and felts or between Rollers were pressed out. A satisfactory effect could be obtained with this procedure cannot be reached, as the squeezed out water cannot drain off sufficiently. When using perforated containers or ίο iron plates, the material is pressed into the holes and is damaged. These evils are supposed to after this. new processes can be avoided by placing the cardboard between perforated, Panels of iron or the like covered with close-meshed gauze or similar material Material is placed and now the whole thing is passed through perforated rollers and pressed out.
Fig. ι zeigt die zwischen gelochte Bleche gelegte Pappe die Druckwalzen passierend und . Fig. 2 aufeinandergelegte Papptafeln zwischen den gelochten Blechen im Schnitt.Fig. Ι shows the cardboard placed between perforated sheets passing the pressure rollers and . Fig. 2 stacked cardboard panels between the perforated sheets in section.
Die Papptafeln α werden zwischen Bleche b The cardboard panels α are between sheets b
gelegt. Die Bleche b, welche aus Eisen oder anderem ähnlichen Material bestehen können,
sind in ihrer ganzen Fläche gelocht, damit das Wasser während des Pressens der Pappe
ständig entweichen kann. Um zu verhüten, daß sich die Pappe in die Löcher c eindrückt,
sind die Löcher c von engmaschiger Drahtgaze d oder ähnlichem Stoff bedeckt. Die von
den Blechen b eingeschlossenen Pappen a · ■
(Fig. 2) werden nun zusammen mit den Blechen b durch zwei ebenfalls gelochte Walzen e und e',
welche verstellbar gelagert sein können, geführt und hierbei gepreßt, wobei durch die
Löcher c der Bleche b und durch die Löcher f der Walzen e und e' das in den Pappen enthaltene
Wasser ständig entweichen kann.
i Es können auch noch zwischen den einzelinen
Pappen gelochte Bleche b gelegt werden, 'und müssen diese Bleche dann auf beiden
[Seiten mit Drahtgaze usw. belegt sein.placed. The metal sheets b, which can consist of iron or other similar material, are perforated over their entire surface so that the water can constantly escape while the cardboard is pressed. In order to prevent the cardboard from being pressed into the holes c , the holes c are covered by close-meshed wire gauze d or similar material. The b of the sheets enclosed paperboard a · ■ (Fig. 2) will now together with the sheets b by two likewise perforated rollers E and E ', which may be adjustably mounted, guided and in this case pressed, where c through the holes of the sheets b and through the holes f of the rollers e and e ' the water contained in the cardboard can constantly escape.
Perforated sheets b can also be placed between the individual pieces of cardboard, and these sheets must then be covered with wire gauze etc. on both sides.
