Method and apparatus for manufacturing a catalyst for purifying an exhaust gas

To provide a manufacturing technique of the exhaust gas-purifying catalyst which can be realized to control the width of the catalyst layer more accurately. A method of manufacturing the exhaust gas purifying catalyst of the present invention has first and second end surfaces, a plurality of substrates hole is provided, each extending toward the first end face to a second end face a method of manufacturing the exhaust gas purifying catalyst having been, facing the first end surface, when passed through a gas toward the first end surface, the air flow control jig to produce a distribution of linear velocity to the flow of the gas , while the slurry is flowing toward the first end face side to the second end surface side, a first position in which the airflow control jig was from the slurry of the first end surface and the facing and the reservoir in between the slurry in the reservoir from includes the distance from the first end face as compared with the first end surface facing and the first position moves to shorter second position. .BACKGROUND 9
