    Abstract: A method for the continuous production of boards having a lignocellulosic fiber material wherein the material is broken up into particles and/or fibers that are dried, glued and formed and pressed to a finished board. The mat is pre-compressed while steam is introduced in such a limited amount during the pre-compression that the temperature of the fibrous mat increases to a value within an interval of 60-95 .degree.Celsius. In this way, the spring back characteristics of the fiber m at is reduced so that its resistance to compression is reduced and the thickness can be reduced more in the pre-compression while the temperature i s not so high to initiate a curing process.

    Abstract: Un método para la producción contínua de tablas de material de fibra lignocelulósica caracterizado porque el material se deshace en partículas y/ofibras que se secan,encolan,y forman una estera que se prensa hasta formar una tabla terminada de modo que se introduce vapor. De acuerdo con la presenteinvención, el vapor se introduce en cantidad limitada en un primer paso de inyección. Esta cantidad se regula de forma que el vapor sólo penetra, calientay cura la capa superficial de la estera. Así, se obtiene una tabla que tenga una capa superficial con una mayor densidad que la capa central de forma que lasiguiente compresión de calibración provee un mayor espesor que permite que la capa central se expanda a la vez que se mantiene la densidad de las capassuperficiales.
