Abstract (en)
Device and method for controlling the pressure in pressing cellulose-based boards, where at least one board initially and lastly during said period of time of the pressing is subjected to a high pressure compared to the pressure of an intermediate period called drying period. During the drying period the board is subjected to at least one breathing cycle, during which the pressure first is decreased to a lower pressure compared to the initial high pressure, and subsequently is increased to a higher pressure compared to the lower pressure of the breathing cycle, and subsequent to the breathing cycle, to a lower pressure compared to the higher pressure of the breathing cycle. <IMAGE>
