ABSTRACT:
A press apparatus and method for pressing water from a paper web is disclosed. The apparatus includes a frame and a first press roll which is rotatably supported by the frame. A second press roll cooperates with the first roll for defining therebetween a pressing nip such that in use of the apparatus, the web extends through the nip for pressing the water therefrom. An elastomeric cover covers at least one of the rolls such that the pressing nip is extended in a machine direction so that the residence time of the web during passage of the web through the nip is increased.
