Abstract
A method of manufacturing a thick multilayer board. Intermediate layers are formed by two consecutive head boxes disposed on a fourdrinier wire, in which layers the pulp suspension consistency is so high that the forming pulp layer reaches in a head box slice or immediately after it such a fibrage degree that fibres cannot significantly move themselves as regards to one another. Dewatering of both pulp layers takes place though a fourdrinier wire.
