PROBLEM TO BE SOLVED: To obtain a new technical means which is simple in a method for producing a shaped, laminated, woody fiber board and can reduce production costs by reusing a solvent recovered in a solvent recovery process for a polyurethane synthetic resin primer. SOLUTION: A conventional processing process in which the polyurethane synthetic resin primer is injected into the woody fiber boards one by one and dried is omitted, and the fiber boards are cut. The shaped, laminated, woody fiber board is subjected to a process including injection, strength increase, and a water repellent effect reaction. COPYRIGHT: (C)2003,JPO
