PATENTAMT.PATENT OFFICE.
Wenn unten geschlossene Hülsen gemäß Fig. i, die namentlich in der chemischen Industrie, in Laboratorien zum Filtrieren, Extrahieren u. dgl. vielfach benutzt werden, durch Eintauchen von entsprechend geformten Siebformen in einen Faserstoffbrei und Absaugen der Flüssigkeit aus dem Innern der Form hergestellt werden sollen, so läßt sich die durch das Ansaugen des dicht auf dem Siebe abgelagerten Faserstoffes gebildete, meist nur dünne Hülse als zusammenhängedes Ganzes schlecht abziehen, da die zur Längsrichtung der Form querliegenden Drähte des Siebes die in die Maschen eingedrungenen Fasern am Abstreifen ohne Verletzung der Hülse hindern. If the sleeves closed at the bottom according to Fig. I, which are particularly in the chemical industry, are widely used in laboratories for filtering, extracting and the like Immersion of appropriately shaped sieve shapes in a pulp and suction the liquid from the interior of the mold are to be produced, the usually only formed by sucking in the fibrous material deposited tightly on the sieve It is difficult to pull off the thin sleeve as a coherent whole, as it faces the longitudinal direction the shape of the transverse wires of the screen remove the fibers that have penetrated the mesh prevent stripping without damaging the sleeve.
Zur Vermeidung dieses Nachteiles ist nach der vorliegenden Erfindung die in die Papierbreimasse einzutauchende, beliebig gestaltete Form aus in der Längsrichtung der Form, d. h. der Abstreifrichtung des Faserstoffkörpers parallel verlaufenden schmalen, nicht durchlöcherten Stäbchen gebildet.In order to avoid this disadvantage, according to the present invention, that is incorporated into the pulp Any shape to be immersed in the longitudinal direction of the shape, d. H. the stripping direction of the fibrous body parallel, narrow, unperforated rods are formed.
In der Zeichnung ist in Fig. 2 ein Ausführungsbeispiel der neuen Form für zylindrische Hülsen dargestellt, deren durch Stäbchen a nach außen abgeschlossenes Inneres mit einer absperrbaren Saugleitung verbunden wird, wenn die Form zwecks Herstellung von zylindrischen Hülsen in bekannter Weise in einen Behälter mit Papierbrei eingetaucht werden soll. Nach einer bestimmten Zeit des Eintauchens wird die Form aus der Flüssigkeit herausgezogen, und man läßt einige Zeit die Luft durch die Filtermassenschicht hindurchsaugen, damit der Papierbrei möglichst von der Flüssigkeit befreit wird. Hiernach kann die Hülse dann leicht ohne Verletzung abgestreift werden, da die schmalen, außen glatten Stäbchen α beim Abziehen des erzeugten Filterkörpers kein Hindernis bieten. Das Abheben der erzeugten Filter von den Formen kann auch wie bekannt durch Einblasen von Druckluft in das Innere der Form befördert werden.In the drawing, an embodiment of the new mold for cylindrical sleeves is shown in Fig. 2 , the interior closed by rods a to the outside is connected to a lockable suction line when the mold is immersed in a known manner in a container with paper pulp for the purpose of producing cylindrical sleeves shall be. After a certain period of immersion, the form is pulled out of the liquid, and the air is allowed to suck through the filter mass layer for some time so that the paper pulp is freed from the liquid as far as possible. The sleeve can then easily be stripped off without injury, since the narrow rods α , smooth on the outside, do not present an obstacle to the removal of the filter body produced. The lifting of the filters produced from the molds can also be promoted, as is known, by blowing compressed air into the interior of the mold.
Statt bei einer dem inneren Hohlräume des zu bildenden Körpers entsprechenden Form schmale Stäbchen zu verwenden, kann man diese Stäbchen natürlich auch bei einer der äußeren Gestaltung des herzustellenden Körpers entsprechenden Form verwenden. Wird eine solche Außenform benutzt, so muß der Papierbrei, wie bekannt, in das Innere der Form eingebracht werden, während die Flüssigkeit nach außen abgezogen wird. Selbstverständlich kann man die Außen- und Innenform auch gleichzeitig anwenden.Instead of a shape corresponding to the inner cavities of the body to be formed If you want to use narrow chopsticks, you can of course also use these chopsticks with one of the Use the appropriate shape for the external design of the body to be produced. Will If such an outer shape is used, the paper pulp must, as is known, be inserted into the interior of the Form can be introduced while the liquid is withdrawn to the outside. Of course you can use the outer and inner shape at the same time.
