  • Publication number: 20030089479
    Abstract: Device for controlling or regulating a basis weight of a web in a web manufacturing process of a web producing machine. The device includes a first control circuit, adapted to adjust the basis weight, that includes at least one adjustable device for influencing the basis weight and at least one basis weight sensor. A second control circuit having at least one sensor for detecting a concentration of incoming backwater is also provided. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

  • Patent number: 6521089
    Abstract: Device and process for controlling or regulating a basis weight of a web in a web manufacturing process of a web producing machine. The device includes a first control circuit, adapted to adjust the basis weight, that includes at least one adjustable device for influencing the basis weight and at least one basis weight sensor. A second control circuit having at least one sensor for detecting a concentration of incoming backwater is also provided. The process includes measuring the basis weight of the material web, adjusting the basis weight of the web with a first control device having at least one device for influencing the basis weight, detecting a retention change in a second control circuit, and counteracting the retention change by influencing a concentration of a stock suspension placed one of onto a wire and between wires.

  • Patent number: 6299731
    Abstract: Process and apparatus for improving a consistency cross-direction profile of a fiber web in the wet section. The process includes distributing a fiber suspension across a machine width from a headbox to one of on a wire and between two wires, adjusting a cross-sectional basis weight by sectionally mixing, across the machine width, a first suspension having a first solid content and a first percentage composition and a second suspension having second solid content that is one of lower and higher than the first solid content, and a second percentage composition of the solids content of the second suspension differs from the first percentage composition, and sectionally admixing at least a third suspension across the machine width, the third suspension having a solids content that is one of lower and higher than the solids content of at least one of the first and second solids content, and having a third percentage composition that differs from at least one of the first and second percentage compositions.

  • Patent number: 5958189
    Abstract: 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.
