  • Patent number: 11155934
    Abstract: A spinning electrode for production of polymeric nanofibres by electric or electrostatic spinning of a polymer solution or melt includes a conduit for the polymer solution or melt. A spinning surface on the conduit is defined by a face of the conduit or an extension on the conduit. A screw shaft is disposed within an inner space of the conduit, wherein the screw shaft and an inner wall of the conduit form a screw conveyor. The screw shaft has a lower end that projects out from the conduit and is connected to a hub of a magnetic coupling.
    Type: Grant

  • Patent number: 10927480
    Abstract: A method, system, and resulting linear fibrous formation are provided wherein a supporting linear formation defines a core that is transported through a spinning chamber. A coating of polymeric nanofibers enveloping the supporting linear formation in the spinning chamber. The coating of polymeric nanofibers comprises a flat stripe wound around the core into a helical form, the flat stripe created from a hollow electrically neutral nanofibrous plume generated in a spinning space above a spinning electrode during spinning by AC electric voltage in the spinning chamber.

  • Patent number: 10808334
    Abstract: The invention relates to a spinning electrode (1) for producing polymeric nanofibers by electrospinning of a polymer solution or polymer melt, containing an inlet pipe (2) of the polymer solution or melt, which ends on its top face (3), whereby around at least a part of the mouth (20) on the top face of the inlet pipe (2) of the polymer solution or melt is formed a spinning surface (4) rounded downwards below the mouth (20), whereby the spinning surface (4) continues as a collecting surface (6) on the outer surface of the inlet pipe (2) of the polymer solution or melt. The invention also relates to a device for producing nanofibers by electrospinning of a polymer solution or melt, which is equipped with at least one spinning electrode (1) according to the invention. In addition, the invention relates to a method for producing nanofibers by electrospinning of a polymer solution or melt, which is based on using the spinning electrode according to the invention.
