An integrated sealing jig is inserted into some of the hexagonal cells of a green honeycomb molding in which multiple hexagonal cells, which are marked off by partitions, open onto the upper and lower surfaces of a cylinder, and the partitions are bonded to each other to seal the hexagonal cells. Portions of the integrated sealing jig are separated and separate jig pieces, which have been separated from some of the hexagonal cells into which the sealing jig was inserted, are extracted. |
