  • Patent number: 9782912
    Abstract: In a green honeycomb molded body including a columnar body of the green honeycomb molded body in which a plurality of hexagonal cells mutually partitioned by partition walls are open at an end surface of the columnar body, a center closing jig is inserted into a part of a plurality of cells at the center of the end surface to join partition walls to each other using the center closing jig, thereby closing the cells at the center of the end surface and the outer periphery of the end surface including the plurality of cells is pressed by a cylindrical outer periphery closing jig having an inner peripheral surface with the inner diameter being continuously reduced from one end to the other end, thereby collapsing the cells at the outer periphery of the end surface to close the cells at the outer periphery of the end surface.

  • Patent number: 9700820
    Abstract: A plurality of inlet-side octagonal cells and outlet-side quadrangular cells partitioned by partition walls on an upper surface and a lower surface are opened in a green honeycomb molded body in which a plurality of through-holes partitioned from each other by the partition walls are open in an end surface of a columnar body. Four outlet-side quadrangular cells having a smaller opening area adjoin around one inlet-side octagonal cell through the partition walls. The partition walls are joined together and the inlet-side octagonal cells are opened while closing the outlet-side quadrangular cells on the inlet side and the outlet-side quadrangular cells are opened while closing the inlet-side octagonal cells on the outlet side in a particulate-matter-removing filter such as a diesel particulate filter.

  • Publication number: 20160271831
    Abstract: An integrated closing tool is inserted into a part of hexagonal cells in a green honeycomb molded body including a plurality of hexagonal cells that open in an upper surface and a lower surface of a columnar body and are mutually partitioned by partition walls to join the partition walls together, thereby closing the hexagonal cells. A part of the integrated closing tool is separated, and tool separated pieces separated from a part of the hexagonal cells into which the closing tool has been inserted are removed.

  • Publication number: 20150376072
    Abstract: A method for manufacturing a honeycomb structure in which some of a plurality of through-holes that are opened at the end face of the cylinder, and mutually divided by partitions, have been closed, wherein a closing jig is inserted into some of the plurality of hexagonal cells of a green honeycomb molded body which has a plurality of hexagonal cells mutually divided by partitions and is open at the end face of the cylinder, thereby contact bonding together the partitions to close the hexagonal cells. Thus, it is possible to close hexagonal cells in a very simple manner during manufacture of the honeycomb molded body.
