An apparatus for processing a web of material by applying a liquid material to the web, heating the web, cooling the web and moistening the web is provided with an applicator that applies the liquid material to the web, a drying apparatus that heats the web to an initial temperature of greater than about 250.degree.F and causes the web to have a moisture content of no greater than about 1.5%, a first cooling apparatus that causes the initial temperature of the web to be reduced to a second temperature no greater than about 210.degree.F and no less than about 100.degree.F, a moistening apparatus that causes the moisture content of the web to be increased to at least about 2.5%, and a second cooling apparatus that causes the web to be cooled to a temperature not greater than about 100.degree.F. The moistening apparatus includes a generator adapted to generate a directed electrostatic field through which the web passes and a sprayer adapted to spray liquid through the electrostatic field and onto the web when the temperature of the web is between about 210.degree.F and 100.degree.F.
