of a spray into the interior 40 of the tube 32 a gas 42 such as air introduced into the interior 40 of the tube 32 entrains the spray so that moistened gas 44 containing a fine mist of liquid entrained droplets is produced a high velocity flow of gas 24 u2032 which may also be moistened is directed along the annular space 20 u2032 between sleeve 12 u2032 and the outside surface of tube 32 so that it exits the nozzle 10 u2032 through sleeve open end 22 u2032 the resulting flow of gas as indicated by arrows 26 u2032 exiting the nozzle 10 u2032 is induced by the shape of head 16 u2032 in conjunction with its spacing dimension and arrangement relative to open end 22 u2032 of sleeve 12 u2032 to a turbulent flow regime which has the effect of causing flows of gas both toward the web surface 28 u2032 as indicated by flow arrows 31 u2032 and away from the surface of a web 28 u2032 as indicated by flow arrows 30 u2032 adjacent the center of the nozzle 10 u2032 while providing a cushion of gas which limits contact between the web 28 and the head 16 u2032 with a minimum of fluttering or other undesired movement of the web 28 u2032 in a direction normal to its surface in this embodiment head 16 u2032 is circular and has a dome shape on its upper surface as shown a circular deflector plate 46 is attached by means of a plurality of.
