Patent ID: 7635419

Claim:
A shoe press apparatus of a paper machine for pressing wet paper through a nip, said shoe press apparatus comprising: a counter roll; and a shoe module disposed adjacent to said counter roll so as to form a nip, and including a cylindrical blanket, and a press mechanism disposed inside said cylindrical blanket, said press mechanism extending in a width direction of said cylindrical blanket and individually pressing a plurality of pressed portions formed on said cylindrical blanket along a traveling direction of the wet paper, toward an outer-surface of said counter roll so that the wet paper is pressed in the nip between said cylindrical blanket and said counter roll, the pressed portions having an upstream side in the traveling direction of the wet paper and a downstream side in the traveling direction of the wet paper, said press mechanism being operable to apply a first oil film to said cylindrical blanket using hydrodynamic pressure at the upstream side of the pressed portions, and being operable to apply a second oil film to said cylindrical blanket using hydrostatic pressure at the downstream side of the pressed portions.
