  • Patent number: 4414757
    Abstract: A web dryer has a plurality of nozzle assemblies. Each nozzle assembly is provided with a flat pressure plate adapted to form a gas flow zone with a moving web. A primary nozzle of the airfoil Coanda type is disposed at the upstream end of the pressure plate and continuously directs gas downstream along the face of the plate. A single secondary nozzle of the impingement type is disposed at the generally right angled downstream terminus of the pressure plate to continuously direct gas initially substantially perpendicularly to the web and to gas flowing downstream along the gas flow zone. The position of the secondary nozzle assures that the full width of the pressure plate is utilized. The gas flow volume through the secondary nozzle is less than half that of the primary nozzle.
