ABSTRACT:
In the coating of a major surface of a strip article, wherein the strip surface is advanced longitudinally past a dam and, immediately beyond the dam, past an extended wall spaced from the strip surface by a gap equal to a desired wet coating thickness, a first liquid coating material is applied to the strip surface ahead of the dam and a second liquid coating material is delivered under pressure to the gap beyond the dam through one or more apertures in the wall to produce a stripe or stripes of the second coating material. The apertures can be provided in a rotatable disk, constituting a portion of the wall; rotary movement of the disk angularly displaces the apertures so as to vary the location and spacing of the produced stripes, for example in a manner simulating the appearance of natural wood grain.
