applying a mask layer to the honeycomb body defining a plurality of channels, wherein the mask layer defines a plurality of holes aligned with the plurality of channels;
rotating a roller drum;
conveying a plugging cement disposed on one side of a carrier web, wherein the carrier web is disposed between the mask layer and the roller drum;
moving the honeycomb body over the roller drum to define a nip between the roller drum and the honeycomb body; and
