ABSTRACT:
A method is disclosed for treating discrete pieces of material, particularly pieces of lignocellulosic furnish, to ensure adequate conductance thereof for orientation in an electric field for electrostatic alignment. The furnish is exposed to a conductance-improving substance of substances, such as an alkali or alkaline earth metal salts of weak acid, quaternary ammonium salts, or gases such as ammonia, chlorine, sulfur dioxide, etc. prior to being subjected to the electric field.
