Abstract
An elongated and generally tubular air bar having pressurized air discharge slot means extending transversely across a web to be floated by the bar, the bar having an internal air delivery passage communicating with the transverse slot means. The interior of the air bar is supplied with pressurized air which first enters the internal passage before it is delivered to the discharge slot means whereby a tortuous path is provided for the air and through which the pressurized air must pass before being discharged by the slot means against the web, thereby cross machine momentum components of air flow are dissipated before the air is discharged by the slot means against the web and uniform drying of the web in a cross machine direction is assured.
