摘要： A system for sealing at least one suction box (3), which adjoins a moving roll sleeve (2) of a suction roller (1) in a machine for producing or processing a fibrous web, such as a paper, tissue or cardboard machine, comprises at least two sealing strips (4) which lie in a sealing manner against the moving roll sleeve (2) via a sealing surface (24) in each case. In the region of the sealing surfaces (24) of the at least two sealing strips (4) and/or on the at least two sealing strips (4) and/or in the at least two sealing strips (4), at least one device (5) for discharging a lubricant (6) coating the at least two sealing strips (4) is provided in each case, said at least one device (5) having a supply line (7) connected thereto, through which the lubricant (6) can be supplied and wherein a separate supply line (7) is provided for each of the devices (5) of the at least two sealing strips (4). The devices (5) for discharging the lubricant (6) are each arranged such that the lubricant (6) can be applied on the run-in side to the at least two sealing strips (4) and, by rotation of the roll sleeve (2), can be transported onto the sealing surfaces (24).

摘要： A paper drying apparatus and method therefor including an infrared drying unit and a vacuum unit, wherein the infrared drying unit emits infrared radiation in a direction toward the vacuum unit. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes between the infrared drying unit and the vacuum unit. The infrared drying unit is positioned on the side of the fabric sheet adjacent to the paper web and the vacuum unit is juxtaposed on the opposite side of the fabric sheet from the infrared drying unit, wherein the vacuum unit draws air through the paper web in a direction from the infrared drying unit toward the vacuum unit. The combination of the infrared drying unit with the vacuum units provides a compact arrangement which efficiently removes moisture from the paper web. After passing by the infrared drying unit, the fabric sheet then conveys the paper web toward a final drying drum where the paper web is transferred from the fabric sheet to the final drying drum through the use of a pressure roll.

摘要： Method and system for applying steam to a paper forming web for the purpose of heating the web to improve the quality of the paper, and withdrawing steam through the use of a vacuum (21) opposite the steam shower (10), by the simultaneously controlled removal of steam at equally spaced increments by the use of a computer based control system (40). The computer based control system (40) uses a selectively actuable stepper motor (110), to effectuate the simultaneous opening of both the steam valve and opposing withdrawal means valve. The system includes a coanda nozzle (18) to cause steam to travel between the sheet (28) and the adjacent surface of the apparatus in a direction opposite to the direction of travel of the sheet (28). Therefore, the apparatus includes a means for creating, housing and providing a supply of steam and a supply of vacuum.
