Abstract: A system comprising: one or more deckle board that are configured to extend along a machine direction of a paper machine and wherein the deckle board includes a stock side and a non-stock side and the stock side includes a microstructure that generates turbulent flow along a face of the deckle board that breaks up a boundary layer when stock contacts the stock side of the deckle board.

Abstract: A multiple mode headbox is provided including a support surface, two or more chambers, and an adjustable roof. Each chamber includes a plurality of nozzles adapted to optionally supply papermaking fibers to the support surface. The adjustable roof is operably configured to adjust over a range of movement such that it defines a forming zone between the support surface and at least one chamber in a first mode, and between said support surface and at least one different said chamber in a second mode.

Abstract: A pulp former's sealing blades extend between the headbox slice and twin forming wires and are bonded and/or pinned to blade supports which mount the blades to the slice. The blade supports have flat mounting surfaces which extend in the machine and cross machine directions and which overlie or underlie the blades supports. The blades may be affixed to the supports with an adhesive film. The supports are in turn mounted to the upper and lower sides of a pulp former headbox slice. After the adhesive bond is formed, holes are drilled through the flexible blades and into the blade supports. The holes are filled with pins which are mounted flush to the pulp side surfaces of the flexible blades. The holes through the flexible blades may be tapered, and the corresponding tapered portions of the pins may be used to clamp the flexible blades to the blade supports.

Abstract: 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.

Abstract: Plies that are formed by respective formers are couched together in a sheet forming device, specifically a machine for the production of a multi-ply fiber web, particularly a paper or cardboard web, or a packaging paper web. At least one of the formers for forming a multi-ply web includes a multi-layer headbox, to which at least two different stocks, or stock partial streams of different composition for different plies are furnished.

Abstract: Headbox for a machine and process for forming the same. The headbox includes a plurality of channels arranged in rows that extend across a width of the machine and in columns substantially perpendicular to the rows, at least one lamella positioned between adjacent rows, a fixing point for the at least one lamella, and lamellar supports positioned after the fixing point, relative to a headbox flow. This includes arranging a plurality of headbox channels into rows and columns, positioning a lamella between adjacent rows, fixing an end of the lamella at a fixing point, and arranging lamellar supports downstream of, relative to a headbox flow direction, the fixing point.

Abstract: The invention refers to a device for feeding a pulp suspension to a dewatering installation, particularly for a tissue machine. It is mainly characterized by one or several one-piece, wedge-shaped, steel lamella tip(s) being provided to separate the individual sectors in a two-layer or multi-layer headbox.

Abstract: A machine for the manufacture of a multi-layer fibrous web includes at least two fibrous web layers and at least two formers; the fibrous web layers each having a lower fines side with a lower fines content and a higher fines side with a higher fines content; and the formers include a first former and a second former, at least one of the two formers being a gap former, with the second former including a couch roll defining a couching zone whereat the lower fines side of the first fibrous web layer is brought into contact with the lower fines side of the second fibrous web layer.

Abstract: 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.

Abstract: A headbox, preferably for a paper machine, has a nozzle chamber with a slice gap, which is confined by a top and a bottom lip wall and by two side walls. The nozzle chamber is divided for the production of multi-layer fibrous stock webs into two or more machine-wide flow channels. For this purpose at least one wedge-shaped partition wall extends through the nozzle chamber from one side wall to the other, with this partition wall projecting through the slice gap in the direction of flow. Each of the two side walls is subdivided along the partition wall into two side wall sections. The partition wall is clamped between the side wall sections in the area of each side wall.

Abstract: A method and a device for forming a web in a papermaking machine. The stock (2) is sprayed out on the wire (3) through a nozzle (1) and the web is formed in a space (8) between an upper lip (5, 18, 19) and a portion of the wire (3). The dewatering is effected in this space (8) by means of an overpressure between the upper lip (5, 18, 19) and the wire (3).

Abstract: A pair of enclosed explosion chamber flowboxes are combined so that the top exit slice plate of the first chamber provides the lower exit slice plate of the second chamber downstream of the first chamber so that pressurized furnishes for a two-ply web are laid one on top of the other over a very short distance.
