Abstract: Apparatus for the application of liquids to moving material, such as patterned application of dyes to moving textile material, including a liquid applicator positioned above the material path of travel for continuously discharging liquid in a row of plural streams downwardly onto the material, a plurality of air jets for selectively deflecting selected of the continuously flowing streams in accordance with a pattern control device, and a collection chamber for receiving the deflected liquid to prevent its contact with the moving material. The deflecting air jets are mounted in a readily separable plate which mates the air jets in notches cut in the dye jet gun bar to provide ease of assembly and disassembly without effecting the relative position of the air jets to the dye jets in the gun bar.
