Verfahren zur Modifizierung von Holzoberflaechen

Procedure for modifying wood surface, especially for layered stripping - involves using thermal ablation, whereby through powerful energy source energy-rich radiation is generated and directed upon area of influence on wood surface.

Abstract
Modification of the wood surfaces takes place through thermal ablation, whereby by the aid of a powerful energy source energy-rich radiation is generated and directed upon the area of influence on the wood surface. The radiation is absorbed in it so that during a short reaction time the surface is heated up in a thin layer in a shock action fashion so strongly that the essential part of the heated volume is evaporated or converted into plasma. ADVANTAGE - Radiation of a higher average intensity is produced at low cost and which is easily integrated into a mechanical wood treatment plant.
