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.
