Abstract: A molded body treating apparatus includes a support, at least one flat plate and a first movement mechanism. The support is configured to support a honeycomb molded body which has a first end portion and a second end portion in a longitudinal direction of the honeycomb molded body and which includes a plurality of cells each extending along the longitudinal direction from a first end at the first end portion to a second end at the second end portion. Either the first end or the second end of each of the plurality of cells is sealed with a plug material paste. The first movement mechanism is configured to move the at least one flat plate along the longitudinal direction to press the either one of the first and second end portions.

Abstract: A method for manufacturing a honeycomb structured body including molding ceramic raw material to form a pillar-shaped honeycomb molded body having a multiplicity of cells disposed in parallel with one another in the longitudinal direction with a cell wall therebetween, and filling in either one of the end portions of each of the cells with a plug material paste, and firing the honeycomb molded body to manufacture a honeycomb structured body comprising a honeycomb fired body, wherein after having filled in either one of the end portions of each of the cells of the honeycomb molded body with the plug material paste, a plug material paste drying process to dry the plug material paste is conducted by blowing hot air to an end face of the honeycomb molded body using a hot air drying apparatus.

Abstract: A honeycomb filter includes at least one pillar-shape honeycomb structured body including a plurality of cells partitioned by partitions, and plugs for sealing upstream openings of a plurality of first cells selected from the plurality of cells and for sealing downstream openings of a plurality of second cells selected from the plurality of cells. Each of the plugs is formed of a material having a greater total content of aluminum, iron, boron, silicon, and free carbon than a material forming the honeycomb structured body.
