IPC: D21F9/00
Filed: 1999-03-05
Abstract: 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.
