Method for coating the outer periphery of a honeycomb structure

摘要

There is disclosed a method of coating the outer periphery (103) of a honeycomb structure (100) with a coating material, the honeycomb structure having a ring-like bulge portion (101) on said outer periphery (103). The method comprises the steps of rotating the honeycomb structure (100); bringng a coating member (1) into contact with a side surface (104) of the honeycomb structure, the coating member including a plate-like spatula (2) in which a cut portion (23) is formed in one side edge portion (24), said side edge portion (24) being an inclined surface inclined on a coating surface side, and a rubber sheet (3) in which a cut (33) is formed in an end portion (31) so that an end surface (32) of the end portion (31) is parallel to a back surface (22) of the spatula (2) when the end portion (31) is bent along the side edge portion (24) of the spatula (2); supplying a slurry coating material to the side surface of the honeycomb structure (100), and coating the side surface of the honeycomb structure with the coating material by pressing the side edge portion (24) of the spatula (2) onto the honeycomb structure (100) via the rubber sheet (3).
