ABSTRACT:
A die for cooling, sizing and smoothing an extrudate includes a mounting plate having an orifice for receiving the extrudate, and a plurality of die members each having an aperture. The die members are mounted on the mounting plate in cascade relationship so that the members are axially spaced and the apertures are in alignment with the orifice in the mounting plate. The die members may be unitary flat metallic discs each having an aperture, or the die members may be a composite of a pair of overlying metallic discs each disc of the pair having an elongated slot extending inwardly from a peripheral edge, with the discs oriented so that the closed end of each slot defines a portion of the aperture.
