摘要： Twin wire former and method for manufacturing a fibrous material web from a fibrous suspension using same. The twin wire former comprises a movable bottom wire belt and a movable top wire belt converging at a twin wire zone. The twin wire zone has a first section, a second section and an end section. A rotating forming roller is disposed at the first section of the twin wire zone, and the to wire and the bottom wire form a wedge-shaped inlet gap at the first section of the twin wire zone. The inlet gap is adapted to receive the fibrous suspension from a headbox. The bottom wire belt and the top wire belt are adapted to form the fibrous web therebetween at the second section of the twin wire zone, and the second section of the twin wire zone has at least one drainage element. A separating device is disposed at the end of the twin wire zone and is adapted to separate one wire belt from another the wire belt. The twin wire zone has a section disposed in a steep downward direction downstream of the forming roller in relation to the movement of the wires. Also disclosed is a method for manufacturing a fibrous material web from a fibrous suspension using a twin wire former.

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.

摘要： Process for homogenizing the property cross direction profile of a continuous web made of paper or cardboard and a paper machine that is suitable for carrying out the above-mentioned process. The process is characterized in that the shrinkage cross direction profile of the material web is homogenized during its manufacturing process by controlling the local composition of the stock suspension sectionally across the width by changing the proportions of components that have different shrinkage behaviors. The paper machine includes an approach flow system having at least two regions that produce different stock suspensions with fiber mixtures that have different shrinkage behaviors. The stock suspension supplies from the approach flow system to the headbox have at least two branches for the at least two different stock suspensions. Near the headbox, a plurality of sectional mixing points are provided, which combine the stock suspensions that have different shrinkage behaviors. Paper is produced from the process and device.

摘要： A former for a machine for the production of a fibrous web, particularly a paper or cardboard web including a headbox equipped with at least one stock suspension feed, one turbulence block equipped with several channels and/or a tube generator equipped with several channels, and a headbox nozzle whose suspension jet strikes an exposed or open surface of a dewatering belt, specifically a wire. Turbulence generating elements are allocated to at least a section of the channels and/or the headbox nozzle, in order to create turbulent flows in the suspension substreams in the channels, or in the headbox nozzle. The side of the suspension stream facing away from the dewatering belt is covered at least partially by a wall. A danger of the suspension stream bursting open is reduced to a minimum. In addition, swirling motions of considerably higher intensity than occur on conventional Fourdrinier wire formers are now permissible.
