US 10,596,721 B2 · Apparatus and method of manufacturing ceramic honeycomb body

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.

Dependent claims

A method of manufacturing a porous ceramic segmented honeycomb body comprising axial channels extending from a first end face to a second end face, the method comprising:

moving at least two porous ceramic honeycomb segments axially past an applicator;
applying adhesive from the applicator to at least one peripheral axial surface of the at least two honeycomb segments as the at least two porous ceramic honeycomb segments are moved axial past the applicator, the at least one peripheral axial surface comprising a surface disposed between the at least two honeycomb segments;
and
moving the at least two honeycomb segments axially through a tapered chamber from a first end to a second end narrower than the first end to simultaneously press a first portion of the at least two honeycomb segments together as the at least two honeycomb segments are moved axially toward the second end of the tapered chamber while applying the adhesive to a second portion of the at least two honeycomb segments, the second portion being axially spaced from the first portion.
