Abstract
An apparatus and method for extruding a thin uniform coating of fluent plastic material about a continuously advancing strand wherein the fluent plastic material is directed radially toward the strand through a constricted annular feed passage. The strand with the fluent plastic material adhering thereto is then advanced through a passageway conically converging to an exit end and effective to develop hydrodynamic pressure forces which center the strand within the passageway.
