ABSTRACT:
A gas nozzle for a dryer apparatus for use with moving webs includes a planar pressure plate with an upstream end portion and a downstream terminus portion and a gas discharge nozzle disposed at the upstream portion of the pressure plate to define a slot for gas flow parallel to the pressure plate. The nozzle includes a first jet forming plate which engages the upstream end portion of the pressure plate and at obtuse angle and which includes a vortex forming step. The nozzle also includes a second jet forming plate located a distance from the first jet forming plate. The two jet forming plates and the step define a passageway for gas flow parallel to the pressure plate.
