An extended press mechanism for removing liquid from a traveling fibrous web (w) including a press nip (P1) formed between first and second members (13, 10) with one of the members being a traveling flexible impervious belt (10) and force means engaging the inner surface of the belt including a sliding shoe (15) facing the belt with the shoe extending transversely across the belt usually of a width less than the belt and also extending in the direction of the belt travel to form an elongated press nip with a means (17) for pressing the shoe toward the belt with a predetermined force, means (20) for providing a film of lubricating fluid between the shoe and the belt and means (22) for removing the excess of lubricating fluid downstream from the shoe including a wiper blade extending toward the belt flexed against the belt to wipe off the lubricant with means (26, 27) to remove the lubricant which is wiped off and means at the side of the shoe to wipe lubricant off the uncompressed portion of the belt and means such as ribs and grooves at the edge of the belt to prevent the lubricant from migrating around the edge onto the web side of the belt. |
