Abstract
A fluid delivery apparatus for applying a fluid composition uniformly to the circumferential surface of a rotating transfer roll comprises a fountain having a chamber. A drain is located in a lower portion of the chamber near one end. Doctor blades meter the surface of the anilox roll. A plurality of inlet ports introduce fluid into the chamber. Each inlet port is downwardly angled toward the drain such that fluid flowing through the inlet port displaces fluid in the lower portion of chamber toward the drain end of the chamber.
