ABSTRACT:
A Coanda dryer nozzle unit in which a nozzle opening formed in a plenum chamber just below and extending along one edge of a wall of the chamber parallel to the web to be dried is connected to the upper surface of the wall by a curved surface to produce a Coanda flow of air over the curved surface and along the upper surface of the wall. A lip along the other edge of the wall has a curved surface which directs the airflow upwardly toward the web and produces a pad of air between the web and the wall.
