ABSTRACT:
A mask apparatus for charging flowable materials into selected cells of a honeycomb structure comprising a solid body having a number of openings extending therethrough which are spaced to coincide with the open ends of the selected cells exposed at the structure's end face, after the mask is positioned across the end face, the flowable material is charged through its openings. In one embodiment, a rigid plate having a number of bores therethrough is provided for charging a plastically formable plugging material into a honeycomb structure in the fabrication of solid particulate filter bodies and other selectively manifolded structures. In a preferred embodiment, a thin transparent polyester film is attached to an open surface of a honeycomb structure and openings melted therethrough. In a second preferred embodiment, a monolithic mask is formed from a flexible elastic polymer and, in addition to openings, has flexible protrusions which assist in aligning the mask on the structure and temporarily plug the cells into which they are inserted preventing them from being inadvertently charged.
