Description

Verfahren zum Herstellen von Preßstücken aus zerkleinertem Holz und härtbarem oder erhärtendem Harz, Kunstharz o. dgl. .Die Erfindung bezieht sich auf das Herstellen von Preßstücken, die aus zerkleinertem Holz, wie Holzmehl mit härtbarem oder erhärtendem Harz, Kunstharz, Teer, Asphalt o. ,dgl., bestehen. Bei dem Herstellen derartiger,Vreßstücke wurde bisher so verfahren, daß zunächst für sich das Holz bis zu einem beliebigen Feinheitsgrad, beispielsweise durch Schleifen, zerkleinert wurde, dann, mit Kunstharz ;gemischt, in vorbestimmter Menge in die Preßform eingebracht und hierauf in einer vorzugsweise beheizten Form gepneßt und verdichtet wurde.Process for the production of pressed pieces from crushed wood and curable or hardening resin, synthetic resin o. The like. The invention relates to the manufacture of pressed pieces made of crushed wood, such as wood flour with hardenable or hardening resin, synthetic resin, tar, asphalt o., The like., Are. When manufacturing Such, Vreßstück has been so far so that initially the wood for itself Chopped up to any degree of fineness, for example by grinding was then introduced into the die in a predetermined amount mixed with synthetic resin and then pressed and compacted in a preferably heated mold.

Die Erfindung hat die Aufgabe, das Herstellungsverfahren für derartige Preßstücke zu vereinfachen und insbesondere folgende Verfahrensstufen zu vermeiden: Das vorherige Zermahlen des Holzes, däs -besondere Vermischen des Holzmehls mit dem Harzoder Kunstharz und gegebenenfalls das Dosieren der für jeden Preßgang erforderlichen Stoffmenge.The invention has the object of the production method for such To simplify pressed pieces and in particular to avoid the following process steps: The previous grinding of the wood, especially mixing the wood flour with it the resin or synthetic resin and, if necessary, the dosage required for each pressing cycle Amount of substance.

Erfindungsgemäß erfolgt das überführen des Holzes in den zerkleinerten Zustand und das Pressen m einem gemeinsamen Arbeitsvorgang, oder zum mindesten wird das Holz gleichzeitig mit dem Einführen in -die Preßform zerkleinert. Am besten. wird als Ausgangsmaterial sein in bekannter Weise mit einer Kunstharzlösung getränktes Holzstück verwendet, das durch eine Düse, ein Gitter oder auch unter ein-oder mehrmaliger Richtungsänderung für den Verschiebungsweg in die Treßform eingebracht wird.According to the invention the transfer of the timber in the crushed state, and the pressing m a common operation, or at least the timber is simultaneously with the introduction into - crushes the mold. Preferably. The starting material used is a piece of wood soaked in a known manner with a synthetic resin solution, which is introduced into the mold through a nozzle, a grid or with one or more changes of direction for the displacement path.

Das Zerkleinern des Holzes erfolgt gleichzeitig mit dem Preßvorgang beim Einbringen des Holzes in die Form. Die für den Preßvorgang erforderliche Holzmenge kann in einfachster Weise durch Abschneiden geeigneter Stücke von einem Stab oder einem anderen Holzstück bestimmt werden. Das innige Durchmischen des-Holzes mit dem Kunstharz erfolgt zum einen Teil schon bei dem Tränken :des Holzes mit der Lösung, zum anderen Teil. beidem Zerkleinern des Holzes während des Einbringers in die Preßform.The wood is shredded at the same time as the pressing process when introducing the wood into the mold. The amount of wood required for the pressing process can be done in the simplest way by cutting off suitable pieces from a rod or another piece of wood. The intimate mixing of the wood with Part of the synthetic resin already takes place during the impregnation: the wood with the solution, to the other part. during the crushing of the wood during the introduction into the press mold.

Soll das Imprägnieren des Holzes vor dem Preßvorgang vermieden werden, so kann auch das Holzstück und das Harz, Kunstharz -o. ,dgl.. getrennt in die Preßform eingebracht werden, indem das Kunstharz beispielsweise an -der Stelle, an welcher das Holz zerkleinert wird, zugegeben, wird. Unter Umständen können die Holzstücke mit Höhlungen, Nuten o. dgl.' versehen werden, in die vor dem PYeßvorgang das Harz, Kunstharz usw.. eingefüllt wird. In diesem Fall wird meist schon vor dem Einbringen des Holzes in die P'reßform, also vor dem endgültigen Zerkleinern beim Vorverdichten des Holzes, das Harz oder Kunstharz in die Holzporen eindringen.If the impregnation of the wood before the pressing process is to be avoided, so can the piece of wood and the resin, synthetic resin -o. , like .. separated into the mold be introduced by the synthetic resin, for example at the point at which the wood is crushed, added, is. Under certain circumstances, the pieces of wood with cavities, grooves or the like ' are provided, in which the resin, Synthetic resin, etc. is filled. In this case, it is usually done before it is introduced of the wood in the press form, so before the final crushing When pre-compacting the wood, the resin or synthetic resin penetrate into the wood pores.
