KNEADING ELEMENTS FOR EXTRUSION APPARATUS AND METHODS OF MANUFACTURING A HONEYCOMB BODY

Abstract:

Kneading elements, extrusion apparatus, and methods of manufacturing honeycomb bodies are described herein. A kneading element (1802) has an inner surface (1804) defining an opening (1806) configured to couple the kneading element (1802) to a shaft (46,48). The kneading element (1802) also has a continuous closed curve elliptical outer surface (1808). The opening (1806) has an axis (1814) that is off-center with respect to a geometric center (1816) of the kneading element (1802) as viewed in a transverse plane perpendicular to the axis.
