ABSTRACT:
A method for plugging a subset of cells of a honeycomb structure having a plurality of open-end cells extending therethrough including providing at least one cylindrically-shaped first roller including an engagement surface having a plurality of outwardly-extending teeth spaced along a length and about a circumference of the at least one first roller, wherein the teeth are spaced so as to engage a first subset of a total number of cells exposed on a first end of the honeycomb structure. The method also includes rolling the engagement surface of the at least one first roller across the first end of the honeycomb structure with the teeth extending into the first subset of cells, thereby deforming the first end of the honeycomb structure and plugging a second subset of the total number of cells substantially different from the first subset of cells.
