ABSTRACT:
Disclosed is an air plenum for surrounding and cooling a tubular extruded film. The plenum has an annular air flow chamber defined in part by an apertured annular distribution plate to which is mounted an annular channel-like one-piece molded housing forming a main flow chamber and having a cross-sectional area which progressively decreases from an air inlet in said housing to a point farthest removed therefrom. The annular air flow chamber receives air from the main air flow chamber through the apertures of the distribution plate and redirects it to an annular outlet nozzle.
