Abstract:
1. A method for manufacturing a plugged honeycomb structure, the plugged honeycomb structure including a plurality of cells extending between two opening ends such that the plurality of cells are defined by porous partition walls and plugged portions disposed so as to plug one of the two opening ends of each of the cells, the method comprising: providing a slurry filler having a container, the container having an open top; storing plugging slurry prepared by slurring a material for the plugged portions in the container; attaching a cover to the open top of the container, the cover having a flat upper face and a plurality of through-holes, the plurality of through-holes connecting an inside of the container to an outside of the container, the plurality of through-holes being disposed so as to correspond to positions of cells to be plugged on an end face of the honeycomb structure; attaching a pipe to each of the plurality of through-holes, the pipe being movable relative to the cover in a direction perpendicular to a cell extending direction; positioning the honeycomb structure on the cover so that the opening ends of the cells to be plugged of the honeycomb structure match positions of the through-holes of the cover; and filling the plugged slurry stored in the container into an inside of the opening ends of the cells to be plugged through the through-holes to form the plugged portions.
