Abstract
A rotating spinning centrifuge is described for spinning yarns of a filament forming spinning material and which includes a centrifugal wheel and an elongate tubular central inlet sleeve fixed to the wheel. A pump is mounted in the inlet sleeve which serves to supply the spinning material under pressure and in a liquid state to the centrifugal wheel, and the pump is preferably designed and constructed as an extruder pump which includes an extruder screw and defining a rotating cylindrical jacket so that the spinning material is advanced under pressure to the centrifugal wheel.
