Abstract
An air bar for floating web material and which includes two slot nozzles, one along each of its longitudinal edges and which nozzles direct air streams toward the web and partially toward one another. The bar has a lengthwise center exhaust means for immediately removing a percentage of the two converging air streams at the center of the air bar and directing them into a separate exhaust chamber within the air bar for ultimate discharge out of the opposite ends of the air bar.
