Abstract
PURPOSE: To manufacture a fibrous board which requires no surface cutting for setting a thickness after drying, by making fibrous slurry into a wet board which has projections and recesses and by hot-pressing the board to such an extent that the projections and recesses are not flattened.
CONSTITUTION: A wet board making machine A comprises a rotary drum 2 having projections and recesses 1 on its peripheral surface and a container 3 for storing a slurry which is produced by mixing fibers with a binder, water, etc. The slurry is rotatively pulled and transferred by the rotary drum 2 of the machine A so that a wet board 5 having projections and recesses 4 on its reverse side is made. The board 5 is conveyed in between an upper and a lower hot plates 7, 8. The board is heated and pressed to such an extent by a hot-press B with spacers 9 for thickness control that the projections and recesses 4 of the board 5 are not flattened. At that time, the volume of the board 5 is transferred into its recesses. As a result, the board is made smooth and a prescribed thickness is maintained. The board is then dried by a drier C, thereby obtaining a fibrous board D.
