Abstract Apparatus for providing the charged particles includes an electrically insulative belt having a surface upon which the organoplastic material is placed and transported to an electrical charging and atomizing zone. Positioned within the charging and atomizing zone is means having an extended or elongated edge at high electrical potential. The extended edge is so positioned as to be substantially transverse of and in close proximity with the surface of the insulative means transporting the organoplastic material. A high intensity electric field extends from the extended edge to, or in some instances, through the substrate if the substrate is porous and fabricated from an insulative rather than a conductive material. The position of the extended edge at high electrical potential relative to the organoplastic material causes the organoplastic material to be formed into charged particles that are projected toward and deposited upon the substrate.
An apparatus for providing charged particles of an organoplastic material adapted to be projected toward a substrate comprising an electrically insulative means comprising a traveling endless belt on which the organoplastic material is provided, a blade means including a relatively sharp wedge-shaped edge disposed within and transversely to said endless belt and associated therewith so as to configure said belt with an attenuated edge, means including an extended edge at high potential adapted to provide a high intensity electric field between the extended edge and the substrate, the extended edge being relatively sharp and extending transversely across said belt and adjacent to said attenutated edge, said extended edge being located so as to be in contact with the organoplastic material on the insulative means, the extended edge and the high intensity field cooperating to provide charged particles of the organoplastic material and means upstream of the attenuated edge for substantially uniformly distributing the organoplastic material on the belt.
