The accuracy of the coating concentration when applying a catalytically active coating to suitable carrier bodies can be increased if, following raw coating with a relatively wide fluctuation range in the coating concentration, excessive or insufficient coating applied is if appropriate corrected iteratively. Excessive coating suspension applied is removed, for example by subsequent suction, while the coating is still in the wet state, whereas insufficient coating suspension applied is topped up, for example by spraying on additional coating suspension.

Method and device for coating a series of support bodies

A method for the sealing of flow channels in an annular zone of a cylindrical honeycomb body. The sealing of the flow channels takes place by introduction of a ceramic compound into the flow channels by means of a nozzle, wherein nozzle and honeycomb body are moved relative to one another with simultaneous guiding of the nozzle past the lateral surface and/or past the end face contour of the honeycomb body.

Method for the unilateral or bilateral sealing or filling of flow
