A paper machine press section has an intermediate press nip defined between a pair of press rolls, a web conveying fabric in the form of a suitable felt or wire travelling between these press rolls together with a web carried thereby while engaging one of the press rolls. An endless fabric means in the form of a suitable felt or wire laps the other press roll to travel also through the intermediate press nip while engaging the web at the side thereof which is directed away from the web-conveying fabric. Thus, while travelling through the intermediate press nip, the web is compressed between the above fabrics. Immediately subsequent to the intermediate press nip, the web-conveying fabric together with the web conveyed thereby lap the press roll which engages the web-conveying fabric through an angle which is at least 5 DEG and which preferably is in a range of approximately 7 DEG -30 DEG . The roll which engages the web-conveying fabric is preferably a smooth-surfaced roll, while the other press roll has a recessed water-receiving recess formed, for example, by grooves, blind bores, or the like. |
