Abstract
An adjustable extrusion die shapes a melt into a non-circular cross-sectional profile form. The wall thickness of the profile is adjustable by moving two adjustment plates orthogonal to each other and transverse to the flow of the melt. Movement of each adjustment plate is restricted to prevent rotation relative to a melt-shaping bushing.
