An extrusion die assembly configured to process a flow of extrusion material traveling in a downstream direction includes a first die component, a second die component and a third die component. The first die component includes a first channel that is substantially coaxial to a longitudinal axis. The second die component is received within a downstream side of the first die component and has a position that is adjustable along the longitudinal axis relative to the first die component. The second die component includes a second channel that is substantially coaxial to the longitudinal axis. The third die component is received within a downstream side of the second die component and has a position that is adjustable along the longitudinal axis relative to the second die component. The third die component includes a third channel that is substantially coaxial to the longitudinal axis.
The present application claims the benefit of U.S. provisional patent application Ser. No. 60/554,599, filed Mar. 19, 2004, the content of which is hereby incorporated by reference in its entirety.
