Claim 8:
9. A method for plugging a subset of cells of a honeycomb structure, the method comprising:
covering a first end face of the honeycomb structure with a mask that comprises a body having an outer edge and a plurality of openings, wherein the outer edge of the body extends outwardly of at least a portion of an outer edge of the first end face and the plurality of openings of the mask is coincident with a plurality of cells of the honeycomb structure;
bringing a film material and the honeycomb structure into contact with each other, the film material having an outer edge that also extends outwardly of at least a portion of the outer edge of the first end face of the honeycomb structure;
applying a force to the film material to push a plugging material through the plurality of openings of the mask and into the plurality of cells of the honeycomb structure; and
adjusting the force applied to the film material based at least in part on a pressure within the plurality of cells to push the plugging material to a predetermined depth within the plurality of cells,
wherein the force applied to the film material is provided by an adjustable piston comprising a planar face that applies the force to the film material based at least in part on one or more of a yaw adjustment and a pitch adjustment to the planar face of the adjustable piston.
