Abstract
A directional diffusion nozzle air bar for utilizing an arrangement of holes to discharge air from a partial round member in the form of circular jets. The direction of discharge of the air is adjustable by a rotatable baffle rotatably mounted within the partial round member. The partial round member includes a plurality of holes along the length of the diffusion nozzle. The air bar provides the ability to adjust the angle of impingement of air on a web by alternating the direction of the circular jets without changing out the air bar. The air bar also provides the ability to profile the drying rate within a specific zone by directing the impingement air from each air bar.
