    Abstract: An apparatus and method of manufacturing a porous ceramic segmented honeycomb body (340,340′) comprising axial channels (216) extending from a first end face (220) to a second end face (224). A plurality of porous ceramic honeycomb segments (204) is moved axially past respective apertures (110) of an adhesive applying device (100). Adhesive (118) is applied through openings (126) in the adhesive applying device (100) onto peripheral axial surfaces of each porous ceramic honeycomb segment (204). The plurality of porous ceramic honeycomb segments (204) enters a wide opening (318) of a tapered chamber (314) and exits a narrow opening (322) of the tapered chamber (314); a tapered wall (326) from the wide opening (318) to the narrow opening (322) presses the plurality of porous ceramic honeycomb segments (204) together forming the porous ceramic segmented honeycomb body (340,340′). The adhesive (118) on the peripheral axial surfaces between respective porous ceramic honeycomb segments (204) is distributed by the pressing.

    Abstract: A honeycomb extrusion apparatus includes first and second vanes with respective first and second face portions. First and second axial widths of a circumferential feed area are respectively defined between the first and second face portions and the outer feed surface of the die body. In further examples, methods include the steps of selectively adjusting the first axial width and the second axial width of the circumferential feed area by respectively adjusting the first and second vane relative to the mask. In further examples, a honeycomb extrusion apparatus includes a plurality of mask segments that each includes an inner peripheral surface portion. Each of the plurality of mask segments are independently adjustable along a respective radial axis.

    Abstract translation: 蜂窝挤出装置包括具有相应的第一和第二面部的第一和第二叶片。 周向进给区域的第一和第二轴向宽度分别限定在模具主体的第一和第二面部分和外部进给表面之间。 在另外的实施例中，方法包括通过相对于掩模分别调节第一和第二叶片来选择性地调节圆周进给区域的第一轴向宽度和第二轴向宽度的步骤。 在另外的实施例中，蜂窝挤出装置包括多个掩模段，每个掩模段包括内周表面部分。 多个掩模段中的每一个可沿相应的径向轴线独立地调节。

    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.

    Abstract: An extruder that includes: an extruder barrel with an inlet end and a discharge end; a rotatable screw element disposed axially within the barrel with a screw inlet end proximate the inlet end and a screw discharge end proximate the discharge end of the barrel; a shaft extending axially through the screw element and comprising a central bore with an opening proximate to the inlet end of the barrel and extending through the shaft to a closed terminal end; and a coolant delivery conduit extending axially within the bore comprising a coolant inlet end proximate to the inlet end of the barrel and a coolant discharge end. The closed terminal end of the bore is located at a predetermined distance upstream from the screw discharge end. Further, the coolant discharge end is located within the bore and proximate to the closed terminal end of the bore.
