  • Patent number: 7374797
    Abstract: A system and method for the continuous fabrication of bichromal spheres by introducing continuous streams of differently colored, pigmented polymer melts to substantially opposite sides of a plurality of spinning disks. The system comprises a first and second extruder which melts a raw polymer material and mixes the melted polymer with a pigment and optionally a charge control agent. The first and second extruders are connected to substantially opposite sides of a plurality of spinning disks with optionally interconnected gear pumps and mixing devices. The instant system and method is useful in fabricating large quantities of bichromal spheres in a continuous manner with a higher degree of uniformity in their physical characteristics.
