METHOD AND APPARATUS FOR THE PRODUCTION OF SHEETS OF FIBROUS MATERIAL TO IMITATE A POROUS STRUCTURE OF NATURAL WOOD A method and apparatus for the production of sheets of material to imitate a porous structure of natural wood. According to the invention, the porous structure of a sample surface of a sheet of natural wood is analysed, taking information from it regarding the coordinates of characteristic points of the lines representing the individual pores. Said information is then stored in a process logic unit comprising a computerised design program, providing data which indicate the dimensions of the pores to be formed. The data and information are then converted into control signals for a computerised engraving system which reproduces this porous structure by engraving it on a sheet of fibrous material. The sheet of porous material made in this way can be used directly for facing or decoration or for creating an artificial veneer.
