ORIENTATION AND DEPOSITION OF FIBERS IN THE MANUFACTURE OF FIBERBOARD ABSTRACT OF THE DISCLOSURE Continuous-line methods and apparatus for orienta- tion and uniform deposition of fibers to enhance directional properties in and production rates of fiberboard produced from lightweight fibrous furnish. A plurality of elongated rod electrodes are predeterminedly spaced over the area of fiber deposition to establish an electric field exerting a torque on discrete fibers tending to orient longitudinal axes of the fibers in the plane of the mat being formed and aligned with the machine forming direction for such mat. Placement of the rod electrodes and controlled rotation about their longitudinal axes yield a combination of electrical and mechanical forces to provide desired orientation and uniformity of deposition over the full area of deposition. Directional properties measured in the compacted and cured fiberboard establish that effective orientation ratios of longitudinal axes of fibers in the preferred direction of 1.2:1 and higher are made available working with lightweight fibrous wood material refined under steam pressure and are available at production rates which are commercially economic.
