摘要： The ledge is arranged transverse to the machine direction in a substantially flexure resistant manner and is adjustable for guiding the wires between which a web of material is formed. The ledge contains a guide surface which faces the wires and has a special contour. For improved control of the pressure changes occurring in the region of the ledge, the ledge contains a supporting member and a pressing member which contains the guide surface. A pressing device is supported at the supporting member and the pressing member can be adjusted in a direction relative to the wires as well as relative to the supporting member by using the pressing device for simultaneously elevating the pressing member and inclining the pressing member with respect to the machine direction. Advantageously the pressing device constitutes a hose which is subjected to a pressurizing medium and thereby deformable. The hose is at least partially imbedded into the supporting member such that its deformation causes movement of the pressing member. For simultaneously inclining the pressing member during such movement, a connecting member is provided between the pressing member and the supporting member. The ledge permits the adjustment of optimum pressures along a sheet forming zone whereby the sheet formation is improved.

摘要： A twin wire former wherein the forming turbulence of a first forming section is quieted by a main forming roller. Behind the main forming roller, as viewed with respect to a predetermined direction of travel of the forming wires, there is accomplished a further forming of the paper web or sheet from the fiber stock suspension in a second forming section. Due to this arrangement there is possible optimum formation of the paper web or sheet with the use of very little dilution water for the fiber stock suspension. Additionally, due to intensive shear forces present in the second forming section flocks formed in the fiber stock suspension and the paper web or sheet at the region of the main forming roller, can be eliminated so that the structure of the paper web or sheet is made more uniform.

摘要： In order to regulate dewatering of the fiber suspension and the formation of the paper web between the upper and lower wires of the papermaking machines, upper ledges are provided along with the upper wire. These upper ledges are particularly constructed so as to have uniform design. Between these upper ledges, there is left free the same distance or spacing. This distance is not smaller than the width of each upper ledge. The individual distances between the upper ledges can be closed by insertable inserts so that the dewatering can be forcibly accomplished at mutually separated zones. Along the lower wire, there are provided lower ledges at a table, and between these lower ledges, it can be adjusted varying distances or spacing therebetween. The mutual distance or spacing between the lower ledges, according to a favorable construction, is always greater than the width of the individual upper ledges plus the distance or spacing of an upper ledge from the next neighboring upper ledge. The lower ledges can be mounted at the table so as to be lengthwise displaceably and individually adjustable in the direction of the lower wire. The table can be selectably positioned vertically as well as horizontally relative to the lower wire. All of these measures also can be accomplished during operation of the papermaking machine. The individual lower ledges are elastically supported against the table and this table is elastically supported against its foundation. It is possible to undertake the web forming operation, during operation of the papermaking machines, in accordance with technological requirements and the time wise as well as localized situations, while protecting the paper web which is to be formed and equally the equipment which is to be operated.

摘要： The de-watering apparatus for a two-wire paper machine is constructed in such a manner that following the convergence of both wires, firstly, a uniform pressure at a forming roll is exerted on the suspension layer located between the wires. Subsequently, both wires pass de-watering rails which may be located in the upper and/or the lower wire. In this case, an under-pressure is exerted at least at the rails located in the upper wire. At least one further de-watering member then follows before both wires are separated again. The de-watering apparatus can also be used after a preliminary de-watering section, for example an endless wire, and also in the direct vicinity of a head box.

摘要： An extended drainage strip (3) is placed next to the primary sieve (5) of a double-sieve mold. It has a liquid-intake space (2), which is disposed between the part of the surface (4) facing the sieve and the sieve (5). Disposed next to the other sieve (6) is at least one adjustable strip (7) arranged so that it can be placed opposite the intake space (2). Intake space (2) has a cross-sectional size that increases, if necessary, in the direction in which the liquid flows. By pressing the adjustable strip (7) against the intake space (2) of the extended strip (3), the shape of the intake space (2) can be controlled, and the suction or intake of the liquid in the intake space (2) is regulated. One object is to achieve steadily increasing suction in the flow direction. This result assists in preventing undesired pressure surges. The drainage device is simplified and thus easy to monitor. Drainage proceeds carefully, with higher retention of fine particles in the sheet of material between the sieves.

摘要： A dewatering device for the web-forming or wet section of a papermaking machine comprises foils arranged transverse to a forming wire, that is to say, extend in the cross-machine direction. Force or powering elements act upon the foils so as to exert a force or pressure upon the forming wire, and thus, bring about dewatering and sheet formation of a layer of fiber stock suspension reposing upon the forming wire. The force elements are constructed and positioned such that additional moments are generated which counteract tilting moments produced by the frictional force present between the foils and the forming wire. In certain arrangements, the force elements also can be interconnected with one another.

摘要： In a multi-ply headbox, the nozzle chamber is subdivided by rigid partition walls into a number of nozzle chambers, and the slice openings or outlet slices are adjustable independently of one another. This is accomplished by providing a pivotable mounting of the partition wall or walls in a guide block, for instance, such pivotable mounting being accomplished by a substantially cylindrical shell or cup bearing structure. The desired pivotable movement or adjustment of the rigid partition wall can be undertaken by an inclined groove-cam guide arrangement effective at a projection of the partition wall or by pressure cushions, such as pressure hoses effective at both sides of the projection.

摘要： The adjusting rod of a lip adjusting mechanism is provided with an indicator which overlies a scale means on which a curved line representative of the lip motion is disposed. Movement of the lip from one position to another is indicated by movement of the indicator along the curved line. A scale is also used with the curved line to measure the displacement of the lip and, thus, the size of the gap defined in part by the lip.

摘要： In a multi-ply headbox of a papermaking machine, a flexible partition foil or sheet is connected by an apparatus to a rigid partition element dividing the nozzle chamber. For rapid replacement of the flexible partition foil or sheet, the apparatus comprises an upper retaining strip and a lower retaining strip which are structured for force-locking or form-closed or form-locking clamping of the flexible partition foil or sheet therebetween and secured at the rigid partition element. Between the upper and lower retaining strips there is provided a pressure chamber of a pressure device, which pressure chamber can be impinged by a pressurized fluid medium for spreading or expanding, if necessary, the upper and the lower retaining strips. The pressure chamber possesses the shape of a continuous groove extending across the entire outlet width of the headbox. This groove is lined with an elastic sealing coating or lining and the space bounded by such elastic sealing coating is connected via lines or conduits to a pressurized fluid medium source.
