Abstract
An extrusion apparatus for extruding thermoplastic material includes first and second die body portions that define a manifold which has a back line and is in fluid communication with an outlet through which the thermoplastic material is extruded and wherein the back line is substantially parallel to the outlet. First and second body bolts join the first and second die body portions together. The first and second body bolts are disposed at first and second equal distances, respectively, from the back line and are further disposed on opposite sides of a centerline of the extrusion apparatus at third and fourth unequal distances therefrom, respectively, and are substantially equally spaced from the outlet.
