ABSTRACT:
Applying a coating composition onto a linearly advancing substrate from at least two spray guns which cyclically traverse the substrate in the direction perpendicular to the movement of the substrate, and which are spaced so as to satisfy the harmonic relationships between the speed of the advancing substrate, the frequency of the spray gun cycles and the spacing of the spray patterns at the surface of the advancing substrate, as defined by the following equation: ##EQU1## WHEREIN: S.sub.p = the spacing between the lines of intersection of the surface plane of the advancing substrate and the imaginary planes generated by the transversely moving axes of adjacent spray patterns, in inches;
