Abstract
A device and a method which is capable of uniformly coating, without waste, any flow passages formed in a raw material with a slurry even if a slurry having high viscosity is fed thereto by an amount required for the use of coating without excess and shortage. When the slurry (S) fed to one end of the base material (M) in which a large number of flow passages (2 . . . ) are formed parallel with each other is forced into the flow passages (2 . . . ) by an air pressure to coat the inner walls (2w) of the flow passages, the slurry (S) is fed from a slurry feeding device (6) by a required amount to a slurry storage part (5) formed at the upper surface part of the base material (M) disposed so that both ends of the flow passages (2 . . . ) can be opened in the upper and bottom surfaces thereof. Then, before the slurry (S) is forced into the flow passages (2 . . . ), a centrifugal force and vibration are allowed to act on the slurry (S) by a liquid level uniformalizing mechanism (7) to uniformalize the level of the slurry.
