Verfahren zur Aufbereitung von Altholz

摘要

The invention relates to a process for separating the surface layer from the core of a piece of wood. During said process, the surface of the piece of wood receives prior mechanical damage, e.g. it is roughened, and subsequently the resultant piece of wood is immersed in water or a water solution until the level of dampness in the surface layer of the wood is at least 30 %. The resultant piece of wood is subsequently steamed at a temperature of from 120 to 160 DEG Celsius, and the surface layer to be removed is consequently superficially etched to such an extent that it can be detached from the piece of wood in a subsequent stage.
