    摘要： Process and a device for detecting a change in the fiber orientation cross-direction profile of a paper or cardboard web in the manufacturing process on a paper or cardboard machine. It is recognized that a change in the fiber orientation cross-direction profile in the web is inferred or determined by way of a characteristic change in the basis weight cross-direction profile or at least one measurement quantity that correlates to it, and/or by way of a characteristic change in the basis weight in the travel direction of the web or at least one measurement quantity that correlates to it. The device includes an arrangement for detecting a change in the basis weight cross-direction profile and/or a characteristic chronological course of the change in the basis weight, which is characteristic for a change in the fiber orientation.

    摘要： Process for setting a uniform characteristic cross-direction profile for a paper web with regard to at least formation, basis weight, and fiber orientation in a paper machine. The paper machine can include a headbox with an adjustable die exit opening and within which the consistency is sectionally adjustable. The process includes measuring and setting a desired basis weight cross-direction profile by adjusting the sectional consistency in the headbox, adjusting the formation cross-direction profile by adjusting a sectional, specific pulp slurry flow rate at the die exit opening, and one of enlarging the die exit opening at positions along a width of the paper machine in which a pulp slurry flow rate is higher than in other positions along the width of the paper machine and increasing the pulp slurry flow rate for positions along the width at which the die exit opening is larger than at other positions along the width. In this manner, a desired fiber orientation cross-direction profile is attained.

    摘要： The invention concerns the wire section of a papermaking machine and a method of removing water from a fiber web in that section. A fiber suspension is discharged from a headbox on at least one and usually between two wires in the forming section. The fiber suspension is dewatered until it eventually reaches the point of immobility at which the fiber orientation is fixed. The rate of removal of water transverse to the direction of travel of the web is controlled at regions across the web. In particular, the rate of water removal is decreased at the edge regions of the wire and the web, as compared with the center region, to improve the transverse formation profile of the web. Various techniques for controlling the rate of water removal are disclosed including using different mesh of the wire at the edge regions and at the center region, a suction forming roll applying different levels of suction at different zones across the wire and the web, and adjustable ledges engaging one of the two wires and being adapted or adjusted to apply different pressure levels to the wire across the web.

    摘要： A wet part of a paper making machine includes a distributor to which a main stream of a stock suspension is fed and which has a number of connections. The connections are connected by means of split stream lines to a machine-wide flow box which has a machine-wide slice nozzle (headbox). The split stream lines are connected (directly or indirectly) to the flow box. The slice nozzle is connected to at least one continuous web-forming screen. At least one collection trough is connected to the screen, as well as, optionally, to a backwater tank to accept the backwater trapped by the collection trough. Dilution water lines are provided to introduce backwater into the split stream lines to adjust the stock density of the split streams. The dilution water lines are connected directly to the collection trough.

    摘要： A paper machine headbox having divided sections for feeding pulp suspensions with different properties therethrough includes a single inlet line and a plurality of feed lines connected thereto. In at least one of the feed lines, there is a separation device which separates certain pulp suspension components from the pulp suspension flowing therethrough. A discharge line connected to the separation device conveys separated pulp suspension components therefrom. A continuing feed line connected to the separation device conveys the remaining pulp suspension to the headbox.
