The present invention is directed to a certain method of catalytically coating a honeycomb monolith, in particular a so-called flow-through monolith. These types of monoliths can be quite precisely be coated by a method using an indirect coating via a displacement body. The present invention further improves this method through controlling the process by monitoring the certain measures.

A nozzle assembly includes an upstream block, an upstream shim, an intermediate shim, a downstream shim and a downstream block arranged in this order in a machine direction MD from the upstream side to the downstream side. A lower end of the nozzle is formed with grooves as guide grooves to support elastics. A first pipe, a dispersion slit for a web and convergence slits for a web define first flow channels wherein the slits are respectively formed with outlets for a web. A second pipe, a dispersion slit for elastics and convergence slits for elastics define a second flow channels wherein the slits are respectively formed with outlets for elastics. The outlets for elastics are formed in the respective guide grooves and each of the outlets for a web lies between each pair of the adjacent outlets for elastics as viewed in the cross direction CD.
