Abstract

PURPOSE:To increase the electric field strength and consequently increase the orientation torque by a method wherein a dielectric is spanned over electrode plates in a manufacture of an orientated board, which is done by heating and compressing a piled-up mat produced by dispersingly filling fibers or particles from above into electrostatic field generated by applying high voltage between electrode plates facing to each other so as to orientate them. CONSTITUTION:Electrostatic field is generated by applying high voltage across the electrode plates 21 and 22 of a high-voltage electrostatic field generating device 2, which is arranged on the underside of a forming conveyer belt 1, so as to pile up particles, which are dispersingly fallen from above, on the top surface of the belt 1, in order to form a mat 6. When phenolic laminates, the base material of which is paper, is employed as a dielectric 23, the orientation property of particles is improved. Dielectric, the dielectric constant of which is 3.0 or more, is more effective. Even when a sheet, cloth or the like is used as one of the constituent elements of the dielectric, the material, the substantial dielectric constant of which is 3.0 or more, must be used.
