Abstract

Apparatus is disclosed for forming and electrostatically orienting a mat of discrete particles of lignocellulosic material on an electrically non-conductive transfer surface and then transferring the directionally oriented mat onto a grounded, moving, electrically conductive mat receiving surface under the continuing influence of an electrostatic field without loss of orientation of the particles of lignocellulosic material making up the mat.
