Abstract

See full text

A method for the continuous production of boards made from feedstock includes A) providing a continuously operating press with an entry adjustment device being movable to define a variable angle entry gap through which the board passes such that the board is subject to compression forces, the variable angle entry gap defined by at least first and second independently variable angle entry gap portions, the first and second portions being flexibly connected and the second portion being flexibly connected at least to one of the heating plates of the press table and press ram; B) moving the feedstock through the variable angle entry gap; C) setting the first independent variable entry gap at a first angular value which falls in a first range from approximately 0.5.degree. to approximately 5.0.degree. relative to a horizontal plane thereby compressing the feedstock under first compressive forces as the feedstock is moved through the first independent variable entry gap; and D) setting the second independent variable entry gap at a second angular value which falls in a second range from approximately 7.0.degree. to approximately 1.0.degree. relative to the horizontal plane, thereby compressing the feedstock under second compressive forces as the feedstock is moved through the second independent variable entry gap portion. A continuously operating press performs the above method.
