Abstract
A honeycomb plugging apparatus that reduces slumping of the plugging patty. Honeycomb plugging apparatus includes a plugging head having an open-ended cavity formed from an end wall and a peripheral wall, and a support substructure provided in the open-ended cavity. Methods of plugging and manufacturing honeycomb bodies using the honeycomb plugging apparatus are provided, as are other aspects.
Claims20
A honeycomb plugging apparatus, comprising:
- a plugging head having an open-ended cavity formed from an end wall and a peripheral wall;
- and
- a support substructure provided in the open-ended cavity.
A method of plugging channels of a honeycomb body, comprising:
- abutting the honeycomb body with an open-ended cavity containing plugging material to form a chamber between the honeycomb body and the open-ended cavity, wherein the open-ended cavity contains a support substructure, and the honeycomb body comprises a mask with openings provided on an end face thereof that provide communication into a subset of the channels of the honeycomb body;
- flowing plugging material from the chamber through the openings into the subset of the channels to form plugs in the honeycomb body and arranging the honeycomb body as a plugged honeycomb body;
- and
- separating the plugged honeycomb body from the open-ended cavity, wherein the support substructure supports remaining plugging material contained in the open-ended cavity after the separating and prevents slumping of remaining plugging material in the open-ended cavity.
A method of plugging a honeycomb body, comprising:
- abutting a honeycomb body comprising a mask on an end face thereof with a volume of plugging material contained in an open-ended cavity to form a chamber between the honeycomb body and the open-ended cavity, the open-ended cavity comprising a support substructure therein;
- flowing plugging material from the chamber into the honeycomb body through openings in the mask to arrange the honeycomb body as a plugged honeycomb body;
- separating the plugged honeycomb body from the open-ended cavity;
- and
- priming the chamber with plugging material for a subsequent plugging process,
- wherein slumping of the plugging material remaining in the open-ended cavity for the subsequent plugging process is reduced by the support substructure supporting the plugging material.
