Abstract
Dye for coloring a carpet is applied to a manifold and then passed through a plurality of nozzles to a plate. The dye floods across the plate and then falls off the edge of the plate in a waterfall-like pattern to a carpet being carried below the plate. This provides for a coloring of the carpet with the dye. The improvement herein is in the recirculation of the dye in the manifold to maintain the particles in the dye in suspension, and further, to interrupt the flow of dye from the nozzles to the plate to better distribute dye particles on the plate for subsequent distribution to the carpet.
