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. A rigid plate having a number of bores therethrough may be provided for charging a plastically formable plugging material into a honeycomb structure in the fabrication of solid particulate filter bodies and other selectively manifolded struc- tures. As an alternative a thin transparent polyester film may be attached to an open surface of a honey comb structure and openings melted therethrough.
