Abstract
A device for applying fluid to a substrate which includes a head member having first and second opposed portions adapted for being fixedly positioned relative to each other. The device is particularly suited for treating a substrate as the substrate moves between the first and second portions. Each portion may in turn include a first channel located at a predetermined distance from the substrate for having a first fluid impinge on the substrate at a first velocity. Additionally, each portion may include a weir adjacent the first channel for having fluid pass thereover at an accelerated rate and thus at a greater velocity than the first fluid, this weir being located at a lesser distance than the first channel. Fluid inlet means is coupled to the respective portions to provide the fluid thereto at desired velocities. Significantly, a fluid blocking means (e.g., an elongated bar) is also included as part of the structure for maintaining the fluids at pre-established levels.
