ABSTRACT:
An elongated air bar having parallel, forwardly opening outlets extending along its length, has partition means in its interior, disposed symmetrically to a plane which is midway between said outlets and extends forwardly and rearwardly through the air bar. The partition means divides the air bar interior into a T-shaped flow distributing compartment and a U-shaped inlet compartment that embraces the stem portion of the flow-distributing compartment. The stem portion of the flow distributing compartment projects rearwardly in the air bar, and pressure air enters that compartment, from the inlet compartment, through port means at its rear, extending all along the air bar. Extremities of the cross-bar portion of the flow-distributing compartment are rearwardly in line with the respective outlets. Like streams of air issue from both outlets, even though pressure air is introduced into the air bar asymmetrically to said plane.
