摘要: A method for the continuous manufacture of board from lignocellulosic material, where the material is disintegrated to particles and/or fibers, dried, glue-coated and formed to a mat and pressed to a finished board. The formed mat is heated with steam and thereafter compressed to near final thickness, whereafter it is pressed to a manageable board in a calibration section.

摘要: A method of continuous manufacture of board of lignocellulosic fiber material where the material is disintegrated to particles and/or fibers, dried, glued and formed to a mat and pressed to a finished board. In a first step the formed mat is heated through by steam and compressed to an at least partially hardened board with substantially uniform density. In a second step the surface layers of the board are compressed to higher density and hardened in a calibration zone to a finished board.

摘要: A method for the continuous production of boards of a ligno-cellulosic fiber material wherein the material is broken up into particles and/or fibers. These are dried, glued and formed to a mat. The mat is compressed to a finished board while steam is introduced. According to the present invention, the compression is performed as a single step and the steam is introduced through one or many compression rollers. By injecting steam in this way a sufficient cure is obtained to withstand the spring back characteristics inherent of the fibers so that it is possible to obtain a finished thickness of the board with one single compression step.

摘要: 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 DEG Celsius. In this way, the spring back characteristics of the fiber mat is reduced so that its resistance to compression is reduced and the thickness can be reduced more in the pre-compression while the temperature is not so high to initiate a curing process.

摘要: A device for compressing and processing a material mat at the manufacture of board of lignocellulosic material, comprising rotary compression rolls. At least one of the compression rolls (2) is formed with a perforated shell surface (6) and an axial duct system (7) located inside of the shell surface. A slide shoe (8) abuts sealingly the end wall of the roll (2) for injection of the processing medium to the mat via the duct system (7) in a restricted sector (9) of the roll (2) where the mat is compressed.
