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.
