  • Method of coating honeycomb bodies with finely divided solid matter
    Patent number: 5165970
    Abstract: A method for the uniform coating of honeycomb bodies with finely divided solid matter from a dispersion in an amount which is below that which arises during customary immersion. To this end, the honeycomb is flooded from below with dispersion, emptied after a dwell time and blown out. Filling time, filling amount, dwell time emptying time as well as the time between emptying and blowing out are measured in such a manner that in order to increase the separated amount of solid matter, filling time, dwell time, pumping-out time and the time between emptying and blowing out are increased but the filling amount is reduced.
