  Verfahren zur Herstellung von Pappe und   Gebrauchsgegenständen   aus Buchenholzabfällen. 



   Die Erfindung betrifft ein Verfahren zur Nutzbarmachung von   Buchenholzabfällen,   vornehmlich solchen der Rotbuche. Es ist bekannt, Abfallholz, darunter auch Buchenholz, in der Weise zu verarbeiten, dass man aus den Abfällen Zellulose herstellte. 



   Im Gegensatz hiesu wird bei der vorliegenden Erfindung von einer chemischen Verarbeitung des Holzes wie bei der Zellulosefabrikation abgesehen und die Herstellung eines Holzbreies durch mechanische Verarbeitung der   Buchenholzabfälle   bezweckt. Aus diesem Grunde wird nicht wie bei der Zellulosefabrikation unter Druck gekocht, also mit einer   Überspannung   des Dampfes, sondern ohne Überdruck, und zwar nur für eine im Verhältnis zu den bisherigen Verfahren kurze Dauer, nämlich eine halbe bis eine Stunde.

   Dadurch wird das an sich nicht sehr hochwertige Abfallprodukt, dessen Fasern bei einer Behandlung wie bel der Zellulosefabrikation ohne Zweifel sehr leiden würden, geschont und die Holzhadern bleiben noch so fest, dass sie bei der nachherige Verarbeitung der gekochten Abfälle in den üblichen Raffineuren, Holzreissern oder dgl. lang und fest genug bleiben, um aus ihnen eine brauchbare Pappe machen zu können. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of cardboard and utensils from beech wood waste.



   The invention relates to a method for the utilization of beech wood waste, primarily that of red beech. It is known to process waste wood, including beech wood, in such a way that cellulose is produced from the waste.



   In contrast to this, the present invention refrains from chemical processing of the wood, as in cellulose production, and the aim is to produce a wood pulp by mechanical processing of the beech wood waste. For this reason, cooking is not done under pressure as in cellulose production, i.e. with an overvoltage of the steam, but without overpressure, and only for a short duration compared to the previous methods, namely half an hour to an hour.

   As a result, the waste product, which is not very valuable in itself, whose fibers would undoubtedly suffer a lot if treated like cellulose production, is spared and the wood flaws remain so firm that they can be used in the subsequent processing of the cooked waste in the usual refiners, wood crackers or Like. Remain long and firm enough to make usable cardboard out of them.
