摘要:
A shoe press apparatus of a paper machine for pressing wet paper through a nip includes a counter roll, and a shoe module disposed adjacent to the counter roll. The shoe module includes a cylindrical blanket, and a press mechanism disposed inside the cylindrical blanket, extending in a width direction of the cylindrical blanket and individually pressing a plurality of pressed portions formed on the cylindrical blanket along a traveling direction of the wet paper, toward an outer-surface of the counter roll so that the wet paper is pressed in the nip between the cylindrical blanket and the counter roll so that a pressure can be applied efficiently in response to a density required for paper solely by the shoe press apparatus.
