Abstract
Air flotation bar for use in floating and drying continuous webs of material in a dryer using dimensionally enlarged air bars. Air flows through three Coanda air slots to provide an air flow distributed over a large area of a passing web to maintain heat transfer capabilities and flotation capabilities. A central Coanda slot air impinges against a web for enhanced heat transfer while outer Coanda slots create a flotation pressure pad.
