Abstract
A process for the production of chipboards, fiberboards, and the like boards, from particles containing lignocellulose and/or cellulose and/or other particles which are electrically non-conductive and have a poor thermal conductivity, combined with at least one binder and water. The process includes the steps of combining the particles, binder and water, forming a layer on a moving support, preheating the layer by high frequency and thereafter pressing the layer into boards with the use of contact heat that produces a steam blast that is effective from the outside of the layer toward its inside and is characterized in that the layer is initially provided with the same amount of moisture throughout, which is sufficient to produce, by means of the high frequency preheating step, a steam blast which proceeds from the inside of the layer into the surface zone thereof.
