Abstract:
An apparatus, comprising:an applicator apparatus that applies a liquid material to a moving web, said liquid material being applied evenly to said web by said applicator apparatus to create a substantially uniform coating of said liquid material on said web;a drying apparatus that heats said liquid material applied to said web by said applicator apparatus, said web being at an initial temperature of greater than about 250.degree. F. when said web passes out of said drying apparatus, said web having a moisture content of no greater than about 1.5% when said web passes out of said drying apparatus;a first cooling apparatus disposed after said drying apparatus, said first cooling apparatus causing said initial temperature of said 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 disposed after said first cooling apparatus, said moistening apparatus receiving said web after said web has been cooled by said first cooling apparatus and when said web has a temperature of between about 210.degree. F. and 100.degree. F., said moistening apparatus causing said moisture content of said web to be increased to at least about 2.5%, said moistening apparatus comprising:a generator adapted to generate a directed electrostatic field through which said web passes; anda sprayer adapted to spray liquid onto said web to moisten said web, said electrostatic field causing said liquid to pass through a confined path between said sprayer and said web; anda second cooling apparatus disposed after said moistening apparatus, said second cooling apparatus causing said web to be cooled to a temperature not greater than about 100.degree. F.
