    摘要: An apparatus for extruding thermoplastic film is disclosed which includes a fully rotational die and an internal cooling means. The die and internal cooling means is rotatable relative to a reservoir for cooling liquid positioned below the die and coaxial therewith. As the die rotates, inlet and outlet conduits of the internal cooling means trace a circular path through the reservoir.
