<p>A method and an apparatus for plugging cells of honeycomb structures are disclosed. The first method covers the honeycomb structyre's end face (18) with a mask (28) having a body and plurality of sized openings positioned to oppose certain cell channels, wherein the outer edge of the body extends radially outwardly from the end face. A film also extends outwardly of the end face, and a plug of material is provided upon the film. The mask and film material are sealed to one another, and a force is applied to the film forcing the material (44) through the mask and into the cells. Also disclosed is adhering a mask (28) to a first end face of the honeycomb structure such that the mask has an outer portion that extends radially beyond an outer edge of the honeycomb; providing a volume of plugging material (44); clamping the outer portion between a first clamping portion (32) and a second clamping portion (54); and transferring the plugging material into the honeycomb.</p> |
