摘要： In a double wire former of a paper machine, a first continuous wire (1) is fed onto an at least partially curved guiding surface (4) so as to converge with a second wire (2), wherein the guiding surface (4) is movable in a form-locked manner relative to the wires. After the dewatering section described above, a further guiding surface (7) follows which, in advantageous embodiments, has an opposite sense of curvature and is fixedly located.

摘要： In a headbox system for a papermaking machine with an adjustable distribution of the fiber stock suspension or pulp over the web width, the flow in the delivery slice is controlled in such a way that, across the web width, also the distribution of the fibers in respect of fiber orientation and quantity has a desired profile. For this purpose, the flow of the fiber stock suspension is controlled such that in the event of a change in the distribution of the fiber stock suspension across the web width, the horizontal component of the flow direction in the delivery slice remains, at all locations, always in the predetermined machine direction and thus transverse flows are avoided and the flow rate in the delivery slice has a predeterminate profile.

摘要翻译：在用于造纸机的流浆箱系统中，纤维原料悬浮液或纸浆在幅材宽度上的分布可调节，输送片中的流动被控制为使得在幅材宽度上，纤维的分布也在对纤维取向和数量的关注具有期望的特征。为此，控制纤维原料悬浮液的流动，使得在纤维料悬浮液横跨幅材宽度的分布发生变化的情况下，输送切片中流动方向的水平分量在所有位置保持，总是在预定的机器方向上，因此避免了横向流动，并且输送片中的流速具有预定的轮廓。

摘要： A drying section of a paper machine includes a plurality of individual drying groups, wherein the drying cylinders of a drying group are served by 2 respective dryer wire or felt that passes over drying cylinders of the drying group and presses a web to be dried against the surface of the drying cylinders. The invention is adapted for either single tier or double tier drying groups. At least one press roll is disposed between and separates two of the drying groups. In one embodiment, the at least one press roll forms a nip with the adjacent drying cylinder, either upstream or downstream, to define a dewatering nip through which the web passes. A dewatering belt passes over the press roll in the nip. The wire for a respective drying group is guided away from the dewatering nip so that only the web and the dewatering belt pass through the press nip. In alternate embodiments, two press rolls may be disposed between the adjacent drying groups, and the two press rolls define a press nip between them. A respective dewatering belt passes over each of the press rolls. One of those press rolls may also be in contact with and define a press nip with the adjacent drying cylinder in the adjacent drying group. An open draw free path may be defined between one of the press rolls and the adjacent drying cylinder.

摘要： A measuring bridge, fixed in place above a moving paper web and disposed crosswise to it, is provided, having a measuring head, movable back and forth--crosswise to the paper web--, for determining the measuring values for judging the thickness of the paper web at the measuring spots or point on top of which the measuring head happens to be. The measuring device, has a process management system, in which a traversing flow program has been installed, in accordance with which the traversing time and/or the reversing time of the measuring head are changed after each traverse of the measuring bridge. Because of this, the frequency of the measurements along the web becomes irregular. This prevents false evaluations of the cross section and, as a consequence, inappropriate control instructions of a control computer.

摘要： A fiber stock suspension is directed from a guide device through the nozzle chamber of the headbox device and out of the slice opening thereof onto a papermaking machine. This nozzle chamber comprises at least two zones or sections. The first zone subsequent to the guide device possesses a relatively low convergence angle or low angle of wall inclination of the headbox device relative to the direction of flow of the fiber stock suspension. The other or second zone is positioned prior to or immediately upstream of the slice opening and possesses a substantially greater convergence angle or angle of wall inclination. In the first zone subsequent to the guide device, an improved flow stabilization or quieting of the flow of the fiber stock suspension occurs after the deflection of the fiber stock suspension and the creation of turbulence by the guide device. In the second zone prior to the slice opening the fiber stock suspension is strongly accelerated. This results in an improved quality of the formation of the paper web and the longitudinal and transverse strength of such paper web which is formed in the papermaking machine.
摘要翻译：纤维原料悬浮液从引导装置引导通过流浆箱装置的喷嘴室，并从其切片开口引导到造纸机上。该喷嘴室包括至少两个区域或部分。引导装置之后的第一区域具有相对于纤维原料悬浮液的流动方向的流浆箱装置的相对低的收敛角或较小的壁倾角。另一个或第二区域位于切片开口之前或紧邻切片开口的上游，并且具有基本更大的收敛角或壁倾斜角度。在引导装置之后的第一区域中，纤维原料悬浮液的流动的改进的流动稳定或静止发生在纤维原料悬浮液的偏转和引导装置产生湍流之后。在切片打开之前的第二区域中，纤维原料悬浮液被强烈加速。这导致纸幅形成的质量提高以及在造纸机中形成的这种纸幅的纵向和横向强度。
