Abstract
A device is constructed for adjusting the concentricity of a die within an extrusion die assembly. The adjustment mechanism involves a series of compound screws having multiple operating threads that employ different pitches to generate a fine adjustment motion. The compound screws are coupled to opposing spring loaded plungers that move against a bias spring in reaction to movement of the compound screws.
