Description

-Es ist bekannt, Hartpapier- bzw. Hartgewebez zylinder durch Aufwickeln eines mit Kunstharzlösung bestrichenen Papiers oder Gewebes auf eine zylindrische Walze unter- Wärme und Druck herzustellen.-It is known, hard paper or hard tissue cylinder by winding a paper or fabric coated with a synthetic resin solution onto a cylindrical Roll to produce heat and pressure.

Das z. B. einseitig mit Kunstharzlösung bestrichene Papier oder Gewebe S (vgl. Fig. i) wird über eine geheizte Vorwärmwalze V geführt -und dann auf die durch eine Schnecke angetriebene zylindrische Walze (Wickelform) W aufgerdllt und durch eine Druckwalze D festgedrückt. Die Wickelform W ruht auf zwei Laufwalzen W, und W2. Die Wickelform W darf nicht vollkommen zylindrisch geschliffen, sondern muß schwach konisch geformt sein, damit der fertige Zylinder- von der Form abgepreßt werden kann.The Z. B. one side with synthetic resin solution coated paper or tissue S (see Fig. I.) Is guided over a heated preheating V -and then aufgerdllt to the driven by a worm cylindrical roll (mandrel) W and pressed by a pressure roller D. The winding form W rests on two rollers W and W2. The winding form W must not be ground completely cylindrical, but must be slightly conical so that the finished cylinder can be pressed from the form.

Der Nachteil dieses Verfahrens liegt darin, daß für jeden Zylinder eine eigene Wickelform W notwendig ist, und das Verfahren wird besondersdann unwirtschaftlich, wenn verschiedene Durchmesser und Mengen bei nur kleinen Stückzahlen gefordert werden.The disadvantage of this method is that for each cylinder a separate winding form W is necessary, and the process is particularly uneconomical if different diameters and quantities are required for only small quantities.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Hartpapier- und Hartgewebezylindern unter Verwendung von eingerollten, dünnwandigen Blechmänteln M (vgl. Fig. 2), auf welche unter großem Druck das isolierte Papier oder Gewebe aufgewalzt wird. Nach Fertigstellung des Zylinders wird die Blechform innen aufgeschnitten (aufgefräst), entfernt und kann dann wieder verwendet werden. Die Druckwalzen D, und D2 können heizbar sein oder es kann eine -Vorwä-rmwalze Vi neben oder außer den bekannten Druckwalzen Di und D2 vorgesehen werden. Eine der Walzen D, oder D2 ist angetrieben. Die Druckwalze D2 kann hochgehoben und die eine Lagerung der Walze D, kann seitlich verschoben werden, damit sich der Blechzylinder zu Beginn leicht einlegen und der fertige Hartpapier- oder Hartgewebezylinder leicht entfernen lassen.The invention relates to a method for producing hard paper and hard tissue cylinders using rolled, thin-walled sheet metal jackets M (see FIG. 2), onto which the insulated paper or tissue is rolled under great pressure. After completion of the cylinder, the sheet metal form is cut open (milled) on the inside, removed and can then be used again. The pressure rollers D and D2 can be heated or a pre-heating roller Vi can be provided next to or in addition to the known pressure rollers Di and D2 . One of the rollers D, or D2 is driven. The pressure roller D2 can be lifted up and the one bearing of the roller D can be shifted to the side so that the sheet metal cylinder can be easily inserted at the beginning and the finished hard paper or hard tissue cylinder can be easily removed.

Die bei dem bekannten Verfahren notwendige .A,bpreßvorrichtung zum Entfernen des fertigen Zylinders von der Wickelform entfällt gemäß der Erfindung.The necessary in the known method .A, bpressing device for According to the invention, there is no need to remove the finished cylinder from the winding form.
