ABSTRACT:
Apparatus for treating a web with a fluid comprises means defining an elongated channel for receiving the web. The fluid is injected into the channel on opposite sides of the web at one or more injection sites. Fluid is evacuated from the channel on opposite sides of the web at one or more evacuation sites. Each injection site is located between two evacuation sites and spaced therefrom such that fluid will flow in opposite directions from the injection site to the adjacent evacuation sites with laminar flow and be evacuated from the channel when the boundary layer of the fluid reaches a predetermined thickness.
