An apparatus and method for applying material to the crests or troughs of corrugated sheet material or selected portions of substantially flat sheet material. A first roller is provided with a plurality of circumferentially-undulating flutes disposed about it peripheral surface. The flutes define first roller crests and first roller troughs. A second roller is provided with a plurality of circumferentially-undulating flutes disposed about its peripheral surface. The flutes define second roller crests and second roller troughs. The first roller and second roller are synchronized so that as the rollers rotate the crests of one roller nest in the troughs of the other roller. The crests or troughs of the first roller are provided with one or more nozzles which apply the desired quantity of coating material to the corrugated sheet material crests or troughs as the first and second roller crests and troughs nest.
