Abstract
A rotatable slot nozzle air bar utilizing a rotatable baffle assembly to directionally discharge air through an attached slot. The direction of discharge of the air is adjustable by a rotatable baffle assembly rotatably mounted within a surrounding outer housing. The rotatable slot nozzle air bar provides the ability to adjust the direction of impingement air on a web by controlling the rotation of the rotatable baffle assembly in the outer housing without changing out the air bar. The rotatable slot nozzle air bar provides the ability to profile the drying rate within the zone by directing the impingement air from the slot nozzle. The rotatable slot nozzle assembly is rotated to change direction of impingement air, thus allowing for operation using direct impingement, induced diffusional flow or a varying combination of either.
