PROCEDURE FOR THE THREE-DIMENSIONAL WORKING OF THE NATURAL WOODEN SURFACES OF WOOD

摘要

The invention relates to a procedure for the three-dimensional working of the natural wooden surface of wood, in the course of which the wood to be worked is placed on a working stand, where the surface to be worked is exposed to the effect of flow containing a fracturing material, and then the wood with worked surfaces is removed from the working stand. The characteristic feature of the procedure according to the invention is that the dry ice pellets of a flow rate of 15÷70 kg/h are used as the fracturing material in the flow (2), and the fracturing material is applied onto the surface (la) of the wood to be worked with the help of a carrying medium in gas state with a flow rate of 2÷7 m3/h and a pressure of 2÷7 bar, and in this way by fracturing the strands of the surface (la) of the wood (1) with different solidity in different depths, a three-dimensional configuration with unique motifs is created on the surface (1a) of the wood (1).
