Description

Verfahren zur Herstellung von Formstücken aus gewickeltem Papier. Für ;die Herstellung von Formstücken aus gewickeltem Papierrohr sind bis jetzt verschiedene Verfahren bekannt. In den meisten Fällen wird -das bereits mit dem @ Klebstoff versehene Papier möglichst fest aufgewickelt, und zwar im kalten oder im warmen Zustand und dann in die betreffende Form hineingepreßt. Weiter hat man versucht, um das Papier für ;das Pressen geschmeidig zu machen, :das Papier in feuchtem Zustand zu wickeln oder in einzelnen Lagen nach und nach in Formen hineinzupressen. Bei a11 diesen Anordnungen benötigt man aber einerseits sehr große Kräfte, um das schon eine sehr feste Masse -bildende Papier in die gewünschte Form zu bringen, anderseits ist das Herauspressen der Feuchtigkeit aus dem Papier nur unter Aufwendung von großer Kraft und unter sehr starker Erwärmung möglich.Process for the production of shaped pieces from wrapped paper. For the manufacture of shaped pieces from wound paper tube have been various up to now Procedure known. In most cases -that is already provided with the @ adhesive Paper wound up as tightly as possible, in cold or warm condition and then pressed into the relevant mold. Next you tried to get the paper for; to make the pressing pliable, to: wrap the paper in a moist state or to gradually press them into shapes in individual layers. With a11 this Arrangements, on the one hand, require a great deal of force to do that Bringing solid mass-forming paper into the desired shape, on the other hand, that is Forcing the moisture out of the paper only with the use of great force and possible under very high temperatures.

Diesem gegenüber wird bei dem neuen Verfahren jede beliebige Form aus einem gewickelten Papierrohr dadurch hergestellt, daß das Rohr nicht fest, sondern lose gewickelt und -dann dieser lose gewickelte Rohrteil, der äußerst nachgiebig ist, im kalten Zustand, also bevor der Klebstoff noch bindet, in die betreffende Form gepreßt wird, was bei der Nachgiebigkeit der losen Wicklung ohne Schwierigkeiten und ohne große Kraft möglich ist. Dann werden die Teile in der Form, damit sie ihre Gestalt nicht verlieren, in ,den Ofen gebracht :und erhitzt. In verhältnismäßig kurzer Zeit wird die Klebemasse flüssig und bindet das Papier so ineinander, daß sich eine der Form entsprechende vollständig feste Papiermasse ergibt. Das Verfahren zeichnet sich von .den bekannten dadurch aus, daß man verhältnismäßig geringe Kraft zum Pressen nötig ,hat, man auch keine besonderen Heizvorrichtungen für die Preßformen verwenden muß und man durch die Nachgiebigkeit des lose gewickelten Papierrohres auch die verwickeltsten Formen in leichter Weise herstellen kann.In contrast to this, any shape is used in the new process made from a wound paper tube in that the tube is not solid, but loosely wound and then this loosely wound pipe part, which is extremely flexible is in the cold state, i.e. before the adhesive still binds, into the relevant Shape is pressed, what with the flexibility of the loose winding without difficulty and is possible without great force. Then the parts are in the shape to make them theirs Do not lose shape, put in, put in the oven: and heated. In proportion In a short time the adhesive becomes liquid and binds the paper together in such a way that a completely solid paper pulp corresponding to the shape results. The procedure is distinguished from the known ones in that they have a relatively low force necessary for pressing, there are no special heating devices for the molds must use and one by the resilience of the loosely wound paper tube can easily make even the most intricate shapes.

PATENTANSPRUCH: Verfahren zur Herstellung von Formstücken aus gewickelten Papierrohren, dadurch gekennzeichnet, daß das mit Klebstoff bestrichene und dann getrocknete Papier lose aufgewickelt, im kalten Zustande in die .gewünschte Form gepreßt und dann erst in der Form erhitzt wird, worauf die Bindung der Papiermasse durch den flüssig gewordenen Klebstoff erfolgt. Claim: A process for the production of shaped pieces from wound paper tubes, characterized in that the paper coated with adhesive and then dried is loosely wound, pressed in the cold state into the desired shape and only then heated in the mold, whereupon the binding of the paper pulp is carried out the adhesive that has become liquid takes place.
