ABSTRACT:
Crosshead apparatus for receiving molten plastic from an extruder to be dispensed as plastic tubing or as a sheathing or jacket about a continuously fed product core such as wire. The crosshead includes a body and manifold within the body having a central passage in which the core to be jacketed is continuously fed. The plastic to be dispensed is constantly heated for temperature stability so as to maintain the flow in a molten state while a predetermined smooth transition flow path forms a substantially annular distribution plane from which the flow concentrically converges about the passing product core at the dispensing site.
