Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A honeycomb structure comprising a columnar body with a plurality of holes being open at an end surface thereof, wherein in a green honeycomb molded body in which a plurality of through-holes mutually partitioned by partition walls are open at an end surface of a columnar body, a part of a plurality of through-holes at the center of the end surface is closed, the partition walls portioning the closed through-holes at the center of the end surface being integrally joined to each other, an outer periphery of the end surface has a chambered portion with the outer diameter being continuously reduced towards the end surface, thereby closing the through-holes at the outer periphery of the end surface, and the green honeycomb molded body has been fired to produce the honeycomb structure. 2. The honeycomb structure according to claim 1 , wherein the through-holes opened at the one end surface of a columnar body have triangular shape and the through-holes opened at the other end surface of a columnar body have hexagonal shape.
