摘要： Water draining device for a paper machine or the like, in particular for a felted press of such a paper machine, including a receiving tank extending at least essentially over the machine width. The receiving tank includes a first chamber that receives arriving water and is under ambient pressure, and a second chamber that is connected to the first chamber and is under vacuum, into which the water collecting in the first chamber is aspirated and from which the water is eventually drained. A water receiving device of improved efficiency is also provided by forming a water receiving device by at least one suction channel projecting into the wedge-shaped area between the upper press roll and the dewatering belt, and extending transverse to the pulp web, which suction channel is connected to a source of reduced pressure.

摘要： Headbox for a paper-making machine including a nozzle extending transversely to the machine running direction across the machine width. The nozzle has a lower and an upper continuous wall each extending across the machine width. The lower nozzle wall is supported by several separate supporting elements distributed across the machine width on a foundation. The supporting elements are non-rigid or flexible plates to permit bending in a direction transversely to the machine running direction. Alternatively or additionally, a swivelable or pivotable upper nozzle wall is connected by several separate supporting members distributed across the machine width to a transverse bar attached above a swivel axis. The supporting members are non-rigid or flexible plates to permit bending transversely to the machine running direction. Alternatively or additionally, an upper arm and a central part of a central component of the headbox are each segmented transversely to the machine running direction, while an inlet-side central part of the central component and the lower nozzle wall are each designed to be continuous transverse to the machine running direction.

摘要： Twin-wire former for producing a fibrous material web from a fibrous suspension and process for separating upper and lower wires of the twin-wire former. The twin-wire former includes a twin-wire zone composed of a lower wire and an upper wire and a plurality of rolls including an inlet roll and an outlet roll. The upper wire is guidable over the plurality of rolls, the inlet roll guides the upper wire to the twin-wire zone, and the outlet roll guides the upper wire toward the inlet roll. A wedge-shaped inlet zone is formed between the upper wire and the lower wire and has an adjustable inlet wedge angle. An upper wire subassembly includes a drainage box adapted to receive suspension water that flows upwardly through the upper wire, and further includes a pivotable common support device, to which the drainage box and the inlet roll are mounted. A stroke device is coupled to the pivotable common support device to lift the pivotable common support device around a first horizontal axle. In this manner, the inlet wedge angle is varied during former operation. After a maximal inlet wedge angle is formed, continued lifting of the pivotable common support device by the stroke device causes the upper wire subassembly to lift up from the lower wire, thereby separating the upper wire from the lower wire. A second horizontal pivot axle associated with the upper wire subassembly and located in a region of the outlet roll is provided. The separating of the upper and lower wires occurs around the second horizontal pivot axle. The process includes lifting the common support device with the stroke device, such that the common support device is pivotably supported by the first horizontal axle and the inlet wedge angle is increased, and, upon maximally increasing the inlet wedge angle, further lifting the common support device with the stroke device, such that the common support device is pivotably supported by the second horizontal axle and is disengaged from the first horizontal axle. In this manner, the upper wire is lifted up from the lower wire.
