摘要

Process for partially coating a cylindrical support body with a coating suspension comprises filling the body from its lower front side with the coating suspension which is measured so that body is only filled to a height which makes up a predetermined fraction of its length; and excess suspension is removed from below so that the required coating amount remains on the support body. Preferred Features: The volume of suspension is measured using a reversible dosing pump which pumps the suspension into the channels of the support body and excess suspension is removed by pumping or suctioning off from the channels. The support body is made from a ceramic or metal.
