摘要： Significant improvements in papermaking control can be achieved by employing an array of sensors that are positioned underneath the wire of the machine to measure the conductivity of the aqueous wet stock. The conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information which can be used to monitor and control the quality of the paper sheet produced. Because CD water weight profile is obtained practically instantaneously, the MD and CD variations are essentially decoupled. Quality improvements to the sheet fabricated will be achieved by providing fast control of the actuators on the machine and by tuning components on the machine to eliminate the sources of variations. Further, the dry stock weight of a sheet of wet stock that is resting on a water permeable moving wire of the papermaking machine can be made employing a water weight sensor element that is positioned adjacent to the wire and that generates signals indicative of the water weight of the sheet of wet stock on the wire. Moreover, the moisture level cross-direction (CD) profile of a sheet of material that is produced can also be measured.
摘要翻译：通过使用位于机器线材下方的传感器阵列来测量水性湿料的导电性，可以实现造纸控制的显着改进。湿料的电导率与湿料中的总水重量成正比; 因此，传感器提供可用于监测和控制所生产的纸张的质量的信息。因为CD水重量曲线实际上是瞬间获得的，所以MD和CD变化基本上是去耦的。通过对机器上的致动器进行快速控制，并通过调节机器上的组件来消除变化的来源，可以实现对制造的片材的质量改进。此外，搁置在造纸机的透水移动金属线上的湿料片材的干燥储存重量可以使用位于铅丝附近的水重量传感器元件来制造，并产生指示水重量的信号的电线上的湿股票。此外，还可以测量所生产的材料片的湿度水平横向（CD）轮廓。

摘要： A papermaking machine including a forming section for forming a paper web, a press section for pressing water from the paper web, and a dryer for drying the paper web is disclosed. The dryer includes a wet end for drying the paper web to at least about 60 percent solids and a dry end for further drying the paper web. The dry end includes at least one series of alternating dryer cylinders and vacuum rolls. A dryer felt transports the paper web as the dryer felt travels about each dryer cylinder and each vacuum roll of the series. In one disclosed embodiment, at least one of the vacuum rolls receives a vacuum of at least about one inch water column (1.5 kilo-pascals, "kPa") to restrain the web as it dries. A method for manufacturing a paper web while restraining it by using the dryer apparatus described above is also disclosed. Drying the paper web under restraint in the dry end of the dryer can substantially reduce cross-machine direction shrinkage and stretch of the web, reduce edge curl, and have other substantial benefits.

摘要： The invention relates to a device and method in a paper machine for guiding a web and in particular in guiding a leader of the web. The device operates in a paper machine in the area between a center roll of the press section and a separate press nip in the press section. The separate press nip is formed between a smooth-faced upper roll and a hollow-faced lower roll. Around this lower roll, a lower felt of the separate press is placed and runs from a suction-transfer roll placed at the proximity of the center roll as a straight run into the separate press nip. At the initial end of the straight run of the felt of the separate press nip, in connection with the guide roll, air-transfer devices are arranged, by whose means a reduced pressure is produced at least across the width of the leader in connection with a closing inlet nip between the felt and the leader and/or in connection with an opening outlet nip defined between the guide roll and the straight run of the felt.

摘要： A regulation system and method in a paper machine for controlling the variation of the basis weight of a paper web in the machine direction in which the basis weight profile of the web is measured by means of a measurement device and a basis weight regulation system receives a signal of the measurement of the basis weight from the measurement device and generates a regulation signal for controlling the flow of thick stock passed into a short circulation circuit in the paper machine by a basis weight valve and/or a regulation pump. The variation of the basis weight in the machine direction in the paper machine is controlled, besides by the short circulation circuit of regulation, also by a substantially faster second circuit of regulation which comprises one or more actuators for controlling the flow rate of the dilution water flow in the dilution profiling system of the headbox and/or the consistency of the dilution water flow across the entire width of the paper web.

摘要： A dryer section employs top-felted and bottom-felted dryer sections each comprised of a single steam-heated drying cylinder with a diameter of about 12 feet. The web is transferred between drying cylinders by a two vacuum roll transfer without an open draw. The dryer fabric wrap on the large dryer cylinders is over 270 degrees resulting in large drying capability per dryer roll. Because each large dryer is followed by another large dryer roll which dries the opposite side of the web, uniformity of drying is maintained. Each dryer cylinder may have its own dryer fabric stretcher and guides. Alternatively, individual dryer fabrics service multiple top-felted dryers and bottom-felted dryers respectively. The web is constrained approximately 96 percent of the time as it passes through the is dryer section. The dryer section can achieve 2.9 inches of dryer surface in the machine direction for every inch of dryer section.

摘要： A method for cutting the leader of the web in a paper or board machine in the dryer section of the machine by a jet of pressurized water. The web is placed against the drying wire when it is being cut, and the jet is directed at the web from the free side of the web. The water jet pressure used is from about 40 bar to about 400 bar, preferably from about 100 bar to about 350 bar, which is produced by an ordinary pressure washer.

摘要： A method for improving the rush transfer of a web, such as a tissue web, is disclosed. The method provides for greater angles of convergence and divergence of the carrier fabric and the transfer fabric at the point of transfer by deflecting the carrier fabric toward the transfer fabric using a deflection element, such as a roll, positioned opposite the vacuum transfer head. The greater angles of convergence and divergence minimize the potential for undesirable macrofolds being formed in the web during transfer.
摘要翻译：公开了一种用于改进幅材（例如纸巾）的纸浆的急转移的方法。该方法通过使用与真空转印头相对定位的偏转元件（例如辊）将载体织物朝向转印织物偏转，从而提供了在转印点处承载织物和转印织物的收敛角度和发散角度。收敛和发散角度越大，转移期间在网中形成不希望的宏观褶皱的可能性就越小。
