ABSTRACT:
Disclosed is an apparatus for extruding thermoplastic compositions comprising an extruder, a die, and a cooling device positioned between the extruder and the die for cooling the heat plastified resinous composition exiting from the extruder to a uniform temperature desired for extrusion through the extrusion die. The cooling device includes at least one enclosed flow path for conveying the resinous composition from the inlet of the cooling device to the outlet of the cooling device, structure for circulating a cooling medium about the entire circumference of each of the resin flow paths, and flow control orifices at the inlet and the outlet of the cooling means across the entire cross-section of each of the resin flow paths.
