Abstract
A method of making a wood particle board containing sticking type resin coated wood particles wherein the top of a layup of the coated wood particles is smoothed to provide a smooth a top surface on the layup and a release agent is applied on the top surface and the so coated layup is consolidated into a board in a consolidating press under heat and pressure with the coated top surface in direct contact with a press platen.
Claims14
A method of making a wood particle board comprising forming a layup containing sticking type resin coated wood particles, smoothing a top surface of said layup, applying a release agent to produce said top surface coated with said release agent and pressing said layup in a press with said coated top surface in direct contact with a press platen to consolidate said layup under heat and pressure to consolidate said layup into a board.
A method of making oriented strand board (OSB) containing a sticking type resin that adheres to a metal surface of a press platen in a surface layer used to form a smooth surface of said board comprising forming a layup of strand layers formed with resin coated strands with said surface layer forming a top of said layup containing said sticking type resin providing a top surface of said layup, smoothing said top surface of said layup without causing significant sticking of said resin to said smoothing device to provide a smoothed top surface, applying a release agent to said smoothed top surface to provide a release agent coated top surface, consolidating said layup in a consolidating press with said coated top surface in contact with a smooth platen of said consolidating press to form said oriented strand board and removing said board from said consolidating press.
