대표청구항 ▼

1. A method of molding a three dimensionally shaped article with sharp definition, from binder coated wood flakes, comprising:forming a loosely felted mat of said wood flakes; salting said loosely felted mat with resinated fines in areas where sharp definition of said article is desired; depositing said mat onto a lower mold die; compressing and heating said mat between an upper mold die and said lower mold die. 2. The method of claim 1, wherein said fines are placed on said loosely felted mat where a bend is to be formed in said article.3. The method of claim 1, wherein said wood flakes have an average length of from about 1¼ to about 6 inches, an average thickness of from about 0.015 to about 0.25 inches, and an average width of less than the average length, and no greater than about 3 inches.4. The method of claim 3, wherein said fines can pass through a 0.25″ diameter screen.5. The method of claim 1, wherein said wood flakes of said mat have an average length of from about 2 to about 3 inches.6. The method of claim 5, wherein said wood flakes of said mat have an average thickness of from about 0.015 to about 0.025 inches.7. The method of claim 6, wherein said wood flakes of said mat have an average width of from about 0.25 to about 1.0 inches.8. The method of claim 7, wherein said fines can pass through a 0.25″ diameter screen.9. The method of claim 1, wherein said fines can pass through a 0.25″ diameter screen.10. A three dimensional article of manufacture with a sharp definition formed from binder coated wood flakes, wherein said wood flakes are formed into a loosely felted mat which is further deposited onto a lower mold die;wherein said mat is salted with fines in areas where sharp definition is desired; wherein said mat is compressed and heated between an upper mold die and said lower mold die. 11. The article of manufacture of claim 10, wherein said fines are placed on said loosely felted mat where a bend is to be formed in said article.12. The article of claim 10, wherein said wood flakes have an average length of from about 1¼ to about 6 inches, an average thickness of from about 0.015 to about 0.25 inches, and an average width of less than the average length, and no greater than about 3 inches.13. The article of claim 12, wherein said fines can pass through a 0.25″ diameter screen.14. The article of claim 10, wherein said wood flakes of said mat have an average length of from about 2 to about 3 inches.15. The article of claim 14, wherein said wood flakes of said mat have an average thickness of from about 0.015 to about 0.025 inches.16. The article of claim 15, wherein said wood flakes of said mat have an average width of from about 0.25 to about 1.0 inches.17. The article of claim 16, wherein said fines can pass through a 0.25″ diameter screen.18. The article of claim 10, wherein said fines can pass through a 0.25″ diameter screen.
