  • Rotary process for forming uniform material
    Patent number: 7786034
    Abstract: A process is provided for issuing material from a nozzle in a rotor rotating at a given rotational speed wherein the material is issued by way of a fluid jet. The material can be collected on a collector concentric to the rotor. The collector can be a flexible belt moving in the axial direction of the rotor. The collected material can take the form of discrete particles, fibers, plexifilamentary web, discrete fibrils or a membrane.
    Type: Grant
