Description

Verfahren zur Herstellung von Gegenständen aus durch Holzschliff gewonnenem Holzstoff. Der aus Holz oder Holzabfällen durch Schleifen unter Zusatz von Wasser gewonnene Holzstoff hat einen verhältnismäßig hohen Wassergehalt. Die aus solchem Holzstoff geformten Gegenstände haben daher ein großes Schwindmaß. Das ist in vielen Fällen, insbesondere bei der He.-stellung von elektrischen Leitungsteilen, von großem Nachteil. Durch die vorliegende Erfindung soll dieser Übelstand dadurch beseitigt werden, daß die durch Holzschliff gewonnene Holzstoffmasse nach dem ersten nassen Schleif- oder Zerreißverfahren zunächst zur Entfernung des Wassergehaltes getrocknet und dann einem zweiten trockenen Reib-, Reiß- oder Quetschverfahren unterworfen und in bekannter Weise unter Zusatz von Sulfitlauge, Wasserglas, Kleister aus Stärke, Kartoffel- oder sonstigem Mehl und ähnlichen Bindemitteln geformt wird.Process for the production of objects from wood pulp Wood pulp. That of wood or wood waste by sanding with the addition of water The wood pulp obtained has a relatively high water content. The ones from such Objects made of wood pulp therefore have a large degree of shrinkage. That is in many Cases, especially in the production of electrical line parts, of great Disadvantage. The present invention is intended to remedy this drawback be that the wood pulp mass obtained by wood pulp after the first wet Grinding or tearing process initially dried to remove the water content and then subjected to a second dry rubbing, tearing or squeezing process and in a known way with the addition of sulphite liquor, water glass, starch paste, Potato or other flour and similar binders is formed.
