<p>An apparatus and method is disclosed for dewatering a paper web. The apparatus includes a head box (12) capable of emitting a continuous, wet paper web (14). The wet paper web has an upper surface and a lower surface. A movable, closed loop forming fabric (16) contacts the lower surface of the wet paper web and conveys the paper web away from the head box. A movable, closed loop transfer fabric (28) contacts the upper surface of the wet paper web and cooperates with the forming fabric (16) to sandwich the paper web therebetween. The wet paper web, forming fabric and transfer fabric are passed through a first dewatering mechanism (34) to remove water therefrom. The wet paper web, forming fabric and transfer fabric are then routed through an air press (36) to remove additional water therefrom. The air press is positioned upstream of a location where the paper web is transferred to the transfer fabric. The method involves the steps of conveying the wet paper web, forming fabric and transfer fabric through the first dewatering mechanism and then through the air press before transferring the paper web onto the transfer fabric.</p> |
