A method is described for bending an extrudate exiting an opening in an die assembly without substantially changing the cross sectional shape of the extrudate. The method includes the step of channeling the flow of extrudate from an extruder through a flow channel and the opening in the die. The opening in the die is rotated with respect to the feed opening to vary the length of the flow channel and pathways along which extrudate flows thereby variably directing flow of the extrudate as the extrudate exits the opening in the die.
