Abstract

Procedure for the preparation of boards and the like, and more particularly for the wet preparation of a board of medium or hard density, reinforced with thermosetting resin, with a central layer having a content of 1-15% (by weight) of thermoset resin, the resin content of the central layer being substantially higher than the resin content of the fixed surface layers of the board, characterized in that a thermosetting resin solution or a fiber slurry having a high content is translated in thermosetting resin in the paste slurry just before or after the exit of the paste slurry from the head box on the fabric of a Fourdrinier type machine.
