A liquid feeding system includes a plurality of adjacent liquid feeding chambers having outlets disposed in a laterally aligned integral assembly to supply liquid to a substrate material passing across the outlets. The liquid feeding chambers are divided by vertical partitions into independent units of substantially uniform width and height. A plurality of liquid control means detachably engage the partitions and extend from the chamber outlets to contact the substrate and provide longitudinal passages having selective restricted openings and solidly enclosed sealed boundaries. The liquid control means may be in the form of like sized apertured inserts fitting into the outlets between the partitions and permitting liquid flow only through the selectively dimensioned apertures. Adjacent inserts may include laterally communicating channels between longitudinal passages and overlapping apertures to provide openings of larger widths and varying patterns. Deflecting elements in the passages improve mixing and blending of liquids. Scraper blades seal the lower edge of the liquid control means and provide additional modifications of the liquid applied to the substrate. Various stripes, blends and combinations of colors are obtainable.
