KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren zur Herstellung von Formungen mit glatter Oberfläche aus wasserhaltigem Holzstoff. Das Verfahren besteht darin, daß diese Masse portionenweise durch Beklopfen geglättet und sodann gegen die Form geworfen wird.The invention relates to a method for producing moldings with a smooth surface made of water-containing wood pulp. The method consists in that this mass is smoothed in portions by tapping and then thrown against the mold.
Bekanntlich ist der feuchte Holzstoff keine homogene knetbare Masse, sondern besteht aus einzelnen Fasern, welche Luft und Wasserteilchen einschließen. Versucht man nun, diese Masse in der für Ton bekannten Art zu formen, so zeigt die Oberfläche des Formlings nicht eine glatte Beschaffenheit. Wollte man die Masse unter starkem Druck, etwa durch hydraulischen Druck, in die Formen pressen, so würde das Verfahren unnötigerweise verteuert, ganz abgesehen davon, daß diese Arbeitsweise besonders stark gebaute Formen beanspruchte.It is well known that the moist wood pulp is not a homogeneous, kneadable mass, but exists made of individual fibers that trap air and water particles. If you try now The surface of the molding shows how to shape this mass in the manner known for clay not a smooth texture. If you wanted the mass under strong pressure, for example by hydraulic pressure into the molds, this would make the process unnecessary expensive, quite apart from the fact that this way of working required particularly strong forms.
Gemäß vorliegender Erfindung gelingt es in einfacher Weise, den oben erwähnten Übel- · stand zu beseitigen.According to the present invention, it is possible in a simple manner to remedy the above-mentioned evils stand to eliminate.
Das vorliegende Verfahren läßt sich naturgemäß nicht nur für reinen Holzstoff, sondern auch für Holzstoffkompositionen in Anwendung bringen.The present process can of course not only be used for pure wood pulp, but also use for wood pulp compositions.
