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, means for selectively deflecting selected of the continuously flowing streams in accordance with a pattern control device, and collection means for receiving the deflected liquid to prevent its contact with the moving material. The apparatus includes a novel flow controller to measure the flow rate of the plural streams from a dye manifold and in response thereto to adjust the flow of dye liquid from the manifold, by opening and closing a valve located in the return conduit from the dye manifold to the dye supply tank.
