ABSTRACT:
A convective dryer for drying a moving coated web has at least one module arranged on one side of the path of web travel. The module includes a housing subdivided into a first chamber opening towards the path of web travel and a second adjacent enclosed chamber. Mutually spaced nozzle assemblies extend laterally across the path of web travel within the first chamber. The nozzle assemblies are connected by a supply duct to air heating and recirculating components in the second chamber. The supply duct gradually diverges in width from a narrow inlet section communicating with the second chamber to a widened delivery end communicating with the nozzle assemblies at the approximate center of the path of web travel.
