摘要： The specification discloses embodiments of a process and related apparatus for conditioning a fibrous web in order to improve the efficiency of drying and calendering thereof. In the process, a moving fibrous web is conditioned after the drier unit of a papermaking machine by applying a flow of moistened gas through one or more arrays of radial jet reattachment nozzles placed in close proximity to the web surface prior to a calendering unit or prior to a steaming unit placed between the nozzles and the calender unit to cool the web and/or increase its moisture content. Webs treated according to the invention exhibit improved properties including less moisture streaking, enhanced smoothness and avoidance of optical property loss.

摘要： A paper web is smoothened by passing the web through a pre-calender device on a paper machine before the application of a coating. The pre-calender device comprises at least one pair of steel rolls, one of which is heated, and a liquid application device which applies a thin film of water to the surface of the web which contacts the heated roll before the web enters the nip between the rolls. The web is then dried after exiting the nip either by wrapping the heated roll and/or by applying heat externally to the web.

摘要： Method for regulating a basis weight of a paper or cardboard web in the manufacturing process. The method includes determining a basis weight at an end of the manufacturing process, calculating a deviation of the determined basis weight from a predetermined target value, adjusting a concentration of a material suspension supplied to a headbox via a first control loop such that the calculated deviation is corrected, one of directly and indirectly measuring a basis weight of a resulting web in a region upstream, with regard to a web travel direction, a drying section, and supplying a signal related to the measured basis weight to a second control loop.

摘要： The moisture application system of the present invention comprises in combination a first means for applying liquid to a paper web and a second means in contact with the web for scraping off excess liquid and spreading the liquid uniformly across the paper web. The moisture application system of the present invention is particularly useful when combined with a machine calender for finishing a paper web.

摘要： A beam with a continuous body (11) of a composite material has end pieces (13) fitted at each end of the body (11) and axle journals (12) fitted on the end pieces (13). Each axle journal (12) is supported on the frame constructions of the machine by means of a support construction (15, 20, 21, 30, 31, 100), in which there are bearing members (21, 31) fitted at a distance from one another in the longitudinal direction of the axle journal (12). The bearing members (21, 31) are fitted in bearing housings (20, 30), and a bending mechanism (40, 50, 60) is fitted in the support construction (15, 20, 30, 100), by which a torque is applied that bends the body (11) of the beam. The beam may support doctor blades, various measurement devices, induction devices, and coating devices.

摘要： A method and apparatus for measuring thickness of a fiber material during manufacture of the fiber material, especially paper in a paper-making machine, comprises a gamma radiation transceiver in communication with a processing/control system. The gamma radiation transceiver is placed at a points along the production path of the web of paper being produced and liberates gamma radiation towards the fiber material. Backscatter of gamma radiation is received by the gamma transceiver also which generates corresponding signals that are received by the processing/control system. The processing/control system processes the signals to determine a thickness profile along a cross-section of the web. The processing/control system may be in communication with or considered a subset of a main processing/control system for the paper-making machine. A gamma radiation shield may be used with the gamma transceiver and is mounted on the side of the paper web opposite the gamma transceiver. The gamma transceiver preferably includes a cover made from a gamma radiation abating material that is selectively positionable over the gamma radiators. Several gamma transceivers may be positioned along the production path of the web of paper and in communication with the processing/control system in order to provide thickness measurement at various points of the web.
摘要翻译：用于在制造纤维材料（特别是造纸机中的纸）时测量纤维材料的厚度的方法和装置包括与处理/控制系统通信的伽马辐射收发器。伽马辐射收发器被放置在沿着正在生产的纸幅的生产路径的点处，并且向该纤维材料释放伽马辐射。 γ辐射的反向散射也由伽马收发器接收，其产生由处理/控制系统接收的相应信号。处理/控制系统处理信号以沿着幅材的横截面确定厚度分布。处理/控制系统可以与造纸机的主处理/控制系统的子集通信或考虑。 γ辐射屏蔽可以与伽马收发器一起使用，并且安装在与伽马收发器相对的纸幅的一侧。伽马收发器优选地包括由伽马辐射消除材料制成的覆盖物，其可以选择性地定位在γ辐射器上方。几个伽马收发器可以沿着纸幅的生产路径定位并与处理/控制系统通信，以便在网的各个点提供厚度测量。
