Patent ID: 7556714

Claim:
A method of operating a papermaking process containing a press section with at least one press nip comprising simultaneously performing the following steps: a. providing a press media for a press section of said papermaking process that has a Mean Flow Pore (MFP) size that is less than the MFP size of a press media that was originally supplied to said papermaking process; b. adding an effective amount of one or more press sheet dewatering additives to said papermaking process prior to a last press nip of said at least one press nip in said press section of said papermaking process; c. providing a paper sheet entering a press nip in said press section, wherein said paper sheet has a sheet moisture ratio of between about 2 to about 9 and wherein said paper sheet is transferred through said press section by said press media; and d. applying an optimum rate of pressure development at said press nip in said press section of said papermaking process so that said pressure is applied to said paper sheet when it enters said press nip, wherein said steps a, b, c, and d either: result in the production of a more uniform paper sheet without the reduction in paper solids exiting the press section that would be expected from performing a, c, and d, alone or in combination with one another; or result in the production of a more uniform paper sheet with an increase in solids content of said paper sheet exiting the press section.
