Abstract
PURPOSE: To obtain a woody fiber board of uniform strength by preventing occurrence of unevenness in hardening and resin spot, by drying woodly fiber applied with a thermosetting adhesive in air and spraying an adhesive-hardening agent immediately before completion of the air-drying process.
CONSTITUTION: Immediately after fabric-untying of wood chips or during the fabric-untying operation, a thermosetting resin adhesive such as urea resin, etc. is added, and this fiber is conveyed by hot air at such a speed as 15W20m/sec. Immediately before completion of the air-drying operation and while the fiber is flyingly conveyed by the hot air, and adhesive-hardening agent (such as, ammonium chloride and ammonium sulfate, etc.) is sprayed in such a manner as to apply the hardening agent uniformly on the fiber. After forming operation, it is finished by thermal pressure forming process.
