Abstract

A method and apparatus for removing excess coating material from a honeycomb body of a catalytic converter. The coated honeycomb body is mounted on an eccentric tappet and is rotated around a first rotational axis with a first rotational frequency such that the distance from the center of gravity of the honeycomb body to the first rotational axis is at least 1.5 times the length of the honeycomb body. The honeycomb body is further rotated around a second rotational axis even out the coating material and provide a more uniform coating surface.
