Abstract
The flow pattern of a polyethylene melt in the working gap of a disc‐type extruder has been visualized. It is shown that there is complex circulating flow in the working gap of the extruder. The flow lines are spirals of Archimedes. An investigation into the qualitative picture of the flow of a polyethylene melt in rotational devices of the “plate‐plate” and “cone‐plate” type showed that in such devices a complex circulating flow is also realized and the flow lines are spirals of Archimedes.
