<p>A metering rod type coating applicator (10) is provided with a metering rod (26) having its peripheral surfaced texture to a texture in a range of Ra 0.5 νm to Ra 1.6 νm to improve the application of coating to a moving surface e.g. the surface cover (14) of a roll (12) of a size press, and permit uniform coating application using higher solids content coatings and/or lower coat weights. Preferably, the rod (26) will be rotated at a speed significantly higher than that conventionally used and preferably with a peripheral velocity in the range of about 15 to 20 m/min.</p> |
