ABSTRACT:
The invention is a process for forming a fiberboard structure with a rough textured surface on a conventional Oliver forming machine. The machine is operated in such a manner as to prevent the dispersion of the fibers in the slurry and to permit the fibers to build up in a lumpy and irregular manner on the rotary vacuum cylinder of the Oliver machine. Also the vacuum of the rotating clyinder is on a low vacuum level of 3-5 inches of mercury and the slurry level is maintained at point 5 inches below the center line of the rotating cylinder. There is thereby formed a fiberboard structure which has a very rough surface texture.
