Description
Verfahren zum Herstellen körperlicher Gegenstände aus Holzstoffklumpen. Körperliche Gegenstände aus feuchten rohen Holzstoffklumpen herzustellen, scheitert stets daran, daß die Holzstoffklumpen durch Pressen keine Verbindung eingehen; es wird vielmehr bei starkem Druck die restliche Feuchtigkeit ausgepreßt, und die Körper fallen beim Herausnehmen aus den Formen auseinander.Method of making physical objects from lumps of wood pulp. Making physical objects from moist, raw lumps of wood pulp fails always make sure that the wood pulp lumps do not enter into a connection by pressing; it Rather, the remaining moisture is squeezed out under strong pressure, and the body fall apart when removed from the molds.
Nach dem neuen Verfahren werden die Holz-@stoffklumpen, deren Oberfläche stets trockener 'ist als das Innere, so in einzelne Fasern zerlegt, daß sie neue Verbindungen in der ihnen geebenen Form eingehen müssen.According to the new process, the lumps of wood @, their surface is always drier than the inside, so broken up into individual fibers that they are new Connections must enter into the form appropriate to them.
Das Zerlegen der Holzstoffklumpen geschieht dadurch, daß sie mittels Druckes durch eine sehrkleineDüseoder einenKanalvon etwa r mm oder geringerem Duichmesser durchgetrieben werden. Von der Düse aus gelangt der zerfaserte Holzstoff unmittelbar in die Form, die der Holz--toff ausfüllen muß. Dabei können die Holz-F. i.offklumpen mittelbar oder unmittelbar durch die feinen Düsen in die Form gedrückt werden, (i. h. die Holzstoffklumpen können entweder erst durch Hindurchpressen durch die Düsen in@'eine formbare Holzstoffmasse übergeführt werden, die dann ihrerseits in die Form gepreßt wird, oder auch ohne Erzeugung eines Zwischenstoffes durch die Düsen gleich in die Form gedrückt werden, bis letztere vollgepzeßt ist.The dismantling of the wood pulp lumps is done by means of Pressure through a very small nozzle or a duct of about r mm or less be driven through. The shredded wood pulp arrives directly from the nozzle in the form that the wood must fill. The wooden F. i.offclump are pressed directly or indirectly through the fine nozzles into the mold (i. H. the lumps of wood pulp can either only be pressed through the nozzles in @ 'a malleable wood pulp mass are transferred, which then in turn in the Mold is pressed, or without generating an intermediate material through the nozzles be pressed straight into the mold until the latter is squeezed full.
So gewonnene körperliche Gegenstände werden dann so lange getrocknet, bis etwa die Hälfte der in ihnen enthaltenen Feuchtigkeit austrocknet, und werden dann in einer um das Schwundmaß kleineren Form nachgepreßt.Physical objects obtained in this way are then dried for so long until about half of the moisture contained in them dries out, and become then re-pressed in a form smaller by the amount of shrinkage.
Man kann, je nachdem die Gegenstände hart oder weich, nachgiebig oder starr, brennbar oder unverbrennbar sein sollen, in bekannter i Weise Binde-, Füll- oder Tränkungsmittel zusetzen. Das Zusetzen von Binde- oder Tränkungsmittel kann schon in der Rohmasse erj folgen, oder die Gegenstände können nach dem crstcn oder nach dem zweiten Nachpressen in j diese Mittel getaucht oder mit ihnen angestrichen oder angespritzt werden. Ferner können diese Mittel auch in die Form vor dem Einpressen des Holzstoffs gegeben werden, die sich darin mit dem Holzstoff während des Pressens mischen.One can, depending on the objects, be hard or soft, yielding or should be rigid, flammable or incombustible, in the known i way binding, filling or add impregnation agent. The addition of binding or impregnating agents can already follow in the raw mass, or the objects can after the crstcn or after the second pressing in j these agents dipped or painted with them or be injected. Furthermore, these agents can also be put into the mold before it is pressed in of the wood pulp, which becomes part of it with the wood pulp during pressing Mix.
Eine für das neue Verfahren anwendbare, an sich bekannte Vorrichtung ist aus der Zeichnung erkennbar.A device known per se which can be used for the new method can be seen from the drawing.
In dem Preßzylindez z, der die angefeuchteten, im Innein noch trockenen, verfilzten Holzstoffklumpen aufnimmt, ist der Kolben 2 bewegbaz, der durch die Kanäle oder Düsen 3, 4, die durch je einen Bajonettverschluß 5, 6 an den Zylinder r angeschlossen sind, die zerfaserten Holzstoff klumpen in die Formen 7, 8 preßt. Die Formen sind mit Handgriffen g, so, z=, 12 versehen. Wird der Kolben 2 nach unten gedrückt, so wird die winzige Flüssigkeitsmenge durch die Düsen 3, q. entweichen wollen und reißt einzelne Holzstoffasern mit sich, die die Formen 7, 8 au -füllen und je nach der Höhlung der Formen die körperlichen . Gegenstände bilden, die dann aus der Form herausgenommen werden.In the press cylinder z, which contains the moistened, inside still dry, picks up matted lumps of wood pulp, the piston 2 is moved through the channels or nozzles 3, 4 each connected to the cylinder r by a bayonet lock 5, 6 are, the shredded wood pulp is pressed into the forms 7, 8 clumps. The forms are provided with handles g, so, z =, 12. If the piston 2 is pressed down, so the tiny amount of liquid through the nozzles 3, q. want to escape and tear individual wood pulp fibers with it, which fill the forms 7, 8 and depending on the Hollow forms the physical. Objects then form out of shape be taken out.
Nach dem beschriebenen Verfahren können Holzstoffkörper sowohl aus getrocknetem Holzstoff (Holschliff) als auch aus Zellstoff hergestell werden.According to the method described, wood pulp bodies can be made from both dried wood pulp (wood pulp) as well as from cellulose.
