Abstract

Process for the production of chip plates and fiber plates, with a previously established density profile, in which mats of material to be compressed, provided with a binder capable of being fully hardened, are disposed between compression plates capable of being heated by electrical means, they are subjected to a compression pressure by press plates of platen presses for the duration of the compression, and after having formed the compression pressure they are subjected to the influence of a heat power in order to adjust the compression temperature, characterized in that for the duration of the compression at least the heat patency is governed or regulated as a function of time according to a previously established program, and thus the density profile of the chip plate is adjusted or of the finished fiberboard.
