Fiberboards are manufactured by defibration of fibre material, admixture of binding agent, drying of the fibres and forming of a fibre mat, which is pressed to boards. The fibre mat is formed of two outer layers and one intermediate central layer. The fibres intended for the central layer are caused at the drying to assume a very low moisture content, suitably 2-8%, in relation to the fibres intended for the outer layers, which preferably are given a moisture content of 15-30%. |
