Abstract
The invention is directed to a shoe press for removing water from a traveling fiber web. The shoe press includes a planar backing surface, and a shoe assembly disposed adjacent to the backing surface. The shoe assembly and the backing surface form a press nip therebetween extending in a running direction of the traveling fiber web. Four felts extend through the press nip and carries the fiber web through the press nip. The shoe assembly includes a plurality of shoes disposed adjacent to each other in the running direction of the fiber web, with each shoe being configured to apply a selected and independent compressive force against the at least one felt and the fiber web.
