摘要： A head box has a preferably fixed flow-carrying wall (11) and a movable flow-carrying wall (13) defining a nozzle-like stock conduit (14) and an outlet slot (15). The movable wall is provided with an adjustable profile bar (35) at the stock outlet slot. For coarse adjustment of the slot width, two lifting devices (21) act on the movable flow-carrying wall. Fine adjustment of the slot width is performed by adjustment spindles (36) acting on the profile bar.To improve adjustment of the stock outlet slot by the movable wall and to use the profile bar adjustment to perform very small corrections to the slot width, a front end section (24) of the movable wall located in the region of the stock outlet slot is flexibly constructed with respect to the remaining part of the wall, and a plurality of adjustment units (33) are spaced across the machine width and act on the flexible end section directly in front of the stock outlet slot.Thereby the movable wall (33) can be adapted with relatively high accuracy to the contour of the fixed wall (11) on the outlet slot side by the adjustment units (33) acting on the flexible end section (24). The immersion depth of the profile bar (35) into the stock conduit is therefore largely constant over the machine width. Cross currents and variable velocities of the stock flow are avoided and the paper's properties are improved.

摘要： The invention concerns a method of controlling the relative flow speed of the layers in a multi-layer headbox with laminae mounted torque-free between upper and lower lips which are stationary when in operation. The invention is characterized in that a difference in speed is produced between the individual layers by causing the static pressure to change differently in the different layers.

The output channel is delimited by two flow guide walls converging toward one another and as a rule by a rear wall. It is divided up into a number of channel sections (32), preferably autonomous, by subdivision of the flow guide walls into wall sections (30, 31) and preferably by subdivision of the rear wall into rear wall sections (37). Each channel section may have at least one input line (40) of its own, as well as (for adjusting the opening of the output slot) a section of part of the mobile wall (35) and an associated regulating system (38, 39).

摘要： A twin-wire former for the production of a web of paper from a fiber suspension. An upper endless loop of wire belt having a lower horizontal run and a lower endless loop wire belt having an upper horizontal run. Guide rolls support the wire belts to define a twin-wire zone. The upstream inlet wedge of the twin-wire zone is disposed at the outlet from a head box. The initial part of the path of the twin-wire zone has a gradual curvature convexly with respect to the lower wire belt, and in that initial portion are positioned guide tables, suction boxes and dewatering elements. This curved initial part is followed by a forming roll within the loop of the upper wire belt. The twin-wires wrap an arcuate sector of the lower region of the forming roll. A support roll follows the forming roll. The support roll is upraised sufficiently to wrap the twin-wires around the bottom of the forming roll and over an arcuate sector at the top of the support roll. Following the support roll, the upper wire separates from the lower wire. In the continuing generally horizontal, slightly descending path of the lower wire with the web on it are disposed a plurality of suction boxes and a lower wire suction roll to define a final dewatering path after the twin-wire zone.

摘要： A double screen former for the manufacture of a paper web has two continuous screens forming together a double screen zone. The one screen runs in the double screen zone across rigid laths that are arranged on the dewatering box at a mutual spacing. Additionally, the other screen runs in the double screen zone across several laths which are supported by means of flexible elements and can be forced on the screen at a selective force. The space between the flexibly supported laths is at least approximately twice as large as the space between the rigid laths.

摘要： Wire section, guidance device, and process of forming a web in a machine for producing a fibrous material web. The device include two revolving endless wire belts, a twin wire zone formed between the two revolving endless wire belts, and a revolving flexible support belt located in a vicinity of the twin wire zone and positioned to support at least one of the two wire belts in a support region. The flexible support belt is generally guided along an at least essentially circular cylindrical path, and the support region includes a support path having an average curvature radius that is greater than a curvature radius of the essentially circular path. The process includes supporting at least one of the two endless wire belts with the flexible support belt in a support region, rotating the flexible support belt along a generally circular path, and deflecting the support belt from the generally circular path in the support region, whereby the support belt in the support regions travels along a support path. An average radius of curvature of the flexible support belt in the support path is greater than an average radius of curvature of the flexible support belt in the generally circular path.
