ABSTRACT:
A press for the production of pressed board with injection of steam utilizes press platens to which the steam is fed to the steam-feed channels from opposite sides in a collision flow, the chanels communicating with steam-nozzle bores opening at the pressing surface and such that the cross section of each channel is equal to at least 60% of the total flow cross sections of the boards communicating with that channel. Before the pressing commences, the channels are through-flushed with steam to flush air from the channels and bores and to evacuate air from the pressed mat by a venturi effect.
