Patent number: 6752895Abstract: An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a water spray including a source of pressurized water such as a pump, a distribution manifold and a plurality of nozzles to direct the water spray at the surface of the slurry. In operation, the water spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.Type: GrantFiled: May 18, 1999Date of Patent: June 22, 2004Assignee: United States Gypsum CompanyInventors: Weixin Song, David Paul Miller
