Date Nov. 24, 1994A method for pre-pressing webs of lignocellulose-containing fibrous material is disclosed including forming the predetermined density, further compressing the mat without the addition of heat to a density approximating that of the predetermined density, and feeding the compressed mat to the finishing press while permiting the controlled expansion of the mat. Apparatus for pre-pressing the web of lignocellulose-containing fibrous material prior to the finishing press is also disclosed.

Abstract: In a method of pre-pressing a formed web of finely-divided lignocellulosic fibre material prior to pressing the web to a finished state in the continuous manufacture of board material, the fibre material is compacted and pressed successively in an entry section (7) of a pre-press (6) subsequent to being formed into a web (11) and subsequent to a first compression and expansion. The web is compressed in this latter pressing process to a density close to the density of the web after the first compression, whereafter the web is allowed to expand to a controlled limited extent in a pre-press expansion section (9), and thereafter transferred to the finishing press. Steam (A, B) is injected into the web (9) when the web is located in the pre-press (6).

Abstract: A method of continuous manufacture of board of lignocellulosic fiber materia l 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 unifor m density. In a second step the surface layers of the bo ard are compressed to higher density and hardened in a calibration zone to a finishe d board.
