Abstract
A moisture control system including an apparatus for discharging independently variable amounts of working fluid toward selected cross-directional sections of a calendered sheet material after the material has left the calender stack and before it is taken up by a collection device. The apparatus includes a plurality of valves spaced across the width of the calendered material to control the amount of fluid applied to each section. Nozzles provided on the valves direct the fluid from the valves toward a surface of the calenderable material. The system permits cross-directional equalization of the moisture content of the calendered material without affecting other physical properties of the sheet, such as sheet finish.
