ABSTRACT:
A method for affecting moisture content of a sheet of paper includes providing a moisture measuring device disposed in a papermaking machine to measure the moisture content of a sheet of paper and create a moisture profile of the sheet of paper, determining the moisture profile of the sheet of paper, and providing a water-spraying device to spray water on a press felt that contacts the sheet of paper during manufacturing. The method further includes selecting one or more zones on the press felt on which to spray water based on the moisture profile of the sheet of paper, and acting on the press felt by spraying water in the one or more selected zones on the press felt to affect the moisture content of the sheet of paper that contacts the press felt after the water has been sprayed.
