Abstract:
A method for treatment of one or more wood elements by pressurization, comprising the steps of embedding the wood element in a pressure medium, increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood element, and reducing the pressure in the pressure medium, whereby the wood element is relieved, characterized in that the wood element contains liquid which during the compression is driven out by the fact that the pressure medium comprises a plurality of solid bodies with intermediate spaces, the solid bodies having a sufficient hardness to maintain the intermediate spaces between the bodies when subjected to pressures over 400 bar, whereby the solid bodies transmit the pressure to the wood element, such that a pressure difference arises between the wood element and said spaces when the pressure medium is pressurized, which pressure difference drives the liquid from the wood element to the spaces.
