Abstract: A bearer for bearing a honeycomb green body includes a solid main body provided with a groove in which a concave arc surface extends along one direction; and a single-layer or multi-layer sponge layer attached to the arc surface of the groove. The sponge layer is curved along the arc surface of the groove and has a bearing surface curved along the arc surface.

Abstract: A method for manufacturing a cylindrical honeycomb fired body including: preparing a cylindrical honeycomb formed body; obtaining a cylindrical honeycomb dried body by drying the cylindrical honeycomb formed body; calculating predetermined parameters (EAVE1, EAVE2, EAVE3 and EAVE4) from average values of distance between a center of gravity position O and an outer peripheral contour in a plurality of predetermined angle ranges; specifying a minimum value of the predetermined parameters; obtaining a cylindrical honeycomb fired body by placing the cylindrical honeycomb dried body on a shelf plate and firing it while passing it through a continuous firing furnace, such that the direction in which the cells of the cylindrical honeycomb dried body extend vertically, and a particular location on the outer peripheral side surface determined according to the minimum value is positioned at the front.

Abstract: A method for manufacturing a pillar-shaped honeycomb fired body including: measuring a firing shrinkage at an end surface of a first pillar-shaped honeycomb firing body at every predetermined angle for one round based on a portion that has been located at the center of a die when a green body passes through the die, obtaining a second pillar-shaped honeycomb formed body having a corrected end surface contour by modifying an annular mask used for extrusion molding based on a result of the measuring, and then obtaining a second pillar-shaped honeycomb fired body by performing drying and firing.
