摘要
(WO2019/070796)
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.

WHAT IS CLAIMED IS:
1. A kneading element for a ceramic batch screw extruder machine, the kneading element comprising: 
 an inner surface defining an opening configured to couple the kneading element to a shaft; and 
 a continuous closed curve elliptical outer surface.
2. The kneading element of claim 1 , wherein the opening comprises an axis that is off-center with respect to a geometric center of the kneading element as viewed in a transverse plane perpendicular to the axis.
3. The kneading element of either of claim 1 or 2, wherein the kneading element comprises a single lobe.
4. The kneading element of any of claims 1 -3, wherein the inner surface comprises at least one of a smooth structure, a splined structure, and a keyed structure.
5. The kneading element of any of claims 1 -4, wherein the outer surface comprises no shoulder and comprises no flat region.
6. The kneading element of any of claims 1 -5, further comprising: 
 a front surface perpendicular to the inner surface and the outer surface and a back surface spaced apart from and parallel to the front surface.
7. The kneading element of any of claims 1 -6, further comprising: 
 an interlocking step on at least one of the front surface and the back surface configured to join the kneading element to an adjacent kneading element.
8. A ceramic batch screw extruder machine, the machine comprising: 
 at least one barrel; 
 a shaft disposed at least partially within the at least one barrel; and 
 at least one kneading element disposed along the shaft and the at least one kneading element comprising (i) an inner surface defining an opening configured to couple the kneading element to a shaft and (ii) a continuous closed curve elliptical outer surface, wherein the opening comprises an axis that is off-center with respect to a geometric center of the kneading element as viewed in a transverse plane perpendicular to the axis.
9. The machine of claim 8, wherein the kneading element comprises a single lobe.
10. The machine of either of claims 8 or 9, wherein the inner surface comprises at least one of a smooth structure, a splined structure, and a keyed structure. 
 1 1 . The machine of any of claims 8-10, wherein the outer surface comprises no shoulder and comprises no flat region.
12. The machine of any one of claim 8-1 1 , wherein the at least one kneading element is disposed at least partially in a backup length region of the extruder.
13. The machine of any one of claims 8-12, further comprising at least one pump and mix screw element disposed along the shaft.
14. The machine of claim 13, wherein (i) the at least one pump and mix screw element comprises a plurality of pump and mix screw elements; (ii) a first portion of the plurality of pump and mix screw elements are disposed upstream of the at least one kneading element; and (iii) a second portion of the plurality of pump and mix screw elements are disposed downstream of the at least one kneading element.
15. The machine of claim 13, further comprising a transition element disposed along the shaft between the at least one kneading element and the at least one pump and mix screw element.
16. The machine of any one of claims 8-15, wherein the at least one kneading element comprises four to eight kneading elements.
17. The machine of any one of claims 8-16, wherein the at least one kneading element comprises a plurality of kneading elements.
18. The machine of claim 17, wherein each kneading element is disposed at an angle of 80° to 100° offset to any adjacent kneading element.
19. The machine of claim 17, wherein each kneading element is disposed at an angle of 35° to 55° offset to any adjacent kneading element.
20. The machine of claim 17, wherein each kneading element is disposed at an angle of 35° to 180° offset to any adjacent kneading element. 
 21 . A method of making a honeycomb body, comprising: 
 kneading ceramic batch in a screw extruder machine; and 
 extruding the batch through a die to form the honeycomb body, wherein the screw extruder machine comprises a kneading element that comprises (i) an inner surface defining an opening configured to couple the kneading element to a shaft; and (ii) a continuous closed curve elliptical outer surface.
22. The method of claim 21 , wherein the opening comprises an axis that is off- center with respect to a geometric center of the kneading element as viewed in a transverse plane perpendicular to the axis.
