  • Patent number: 11041271
    Abstract: Vibration sensors can be used in paper making systems and methods to determine various aspects of the paper making operation. Vibration sensors, for example, positioned on cleaning blades configured to clean various deposits off of rollers in a paper making system can output vibration data that can be indicative of the vibration of the blade. The vibration data can be analyzed in order to characterize the cause of the vibration and/or the location of the vibration within a paper making system. If the vibration data satisfies a predetermined condition, a corrective action can be initiated. Different corrective actions can be initiated based on the characterized cause and/or location of the vibration in order to effectively improve the operation of the system while minimizing costly system shut downs and major maintenance.

    Abstract: A method includes passing a web of material over a deflector having a backstep, where the backstep causes the web to deflect towards the deflector. The method also includes capturing measurements of one or more characteristics associated with the web at one or more locations downstream of the backstep. In addition, the method includes identifying a cross direction (CD) profile of machine direction (MD) tension on the web using the measurements. The method could further include generating a Coanda airflow between the web and the deflector. The measurements could include pressure measurements identifying air pressures in a space between the web and the deflector and/or deflection distance measurements identifying distances by which the web is deflected towards the deflector.

  • Patent number: 8906202
    Abstract: This invention relates to a method and system for detecting contamination of boiler condensate and/or boiler feedwater in a papermaking process. The method includes measuring an oxidation-reduction potential at one or more locations in the boiler condensate and/or the boiler feedwater of the papermaking process with one or more corrosion stress monitoring devices. A controller is operable to assess whether the measured or a calculated oxidation-reduction potential is within an optimum range. The controller is operable to cause transmission of a signal to direct feeding an effective amount of one or more reductants and/or one or more pH-controlling chemicals into the boiler feedwater and/or one or more a satellite feed locations of the papermaking process.

  • Patent number: 8877010
    Abstract: Properties of an end product, such as paper, paperboard or board, are important for the user of the end product. To be able to manufacture an end product of desired quality, it is important to know what kind of paper pulp used for manufacturing the end product results in a particular kind of property of the end product. Embodiments provide a method and an apparatus for generating a model, which model connects at least one property of the end product with at least one property of the paper pulp. On the basis of the model, also the manufacturing process can be controlled.

  • Patent number: 8871059
    Abstract: Processes for making fluff pulp sheets mechanically eliminate many unwanted fiber-to-fiber bonding (fiber bundles) in the sheet. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break fiber bundles. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. Shoe presses can be used to dewater the web after it is subjected to the pulsating shear forces.

  • Patent number: 8764942
    Abstract: Methods to preserve starch present in pulp are provided and also methods to control calcium precipitation and/or scaling in digesters or BOD systems. The methods can be performed as part of a papermaking process. Process water containing pulp can be treated with a chloramine. Process water containing pulp with native starch can receive a double treatment with at least one biocide, such as chloramine, and at least one oxidant, such as sodium hypochlorite. The treatment can be performed in any suitable manner. The treatment can be performed at one or more stages or locations in a papermaking system. A target residual chloramine value or range can be achieved by the treatment. Packaging sheets/boards and other paper products manufactured using the methods provided exhibit superior strength and other desirable characteristics.

  • Patent number: 8728276
    Abstract: A method includes receiving a measurement associated with an anisotropy of a first surface and a measurement associated with an anisotropy of a second surface of a sheet of material. The method also includes adjusting an operating parameter associated with a headbox based on the measurements. The headbox is associated with manufacture of the sheet. The operating parameter could include a jet speed, a jet impingement angle, a jet thickness, a slice opening, and/or a slice apron projection. Adjusting the operating parameter could be based on a difference between a measured anisotropy of the first surface and a measured anisotropy of the second surface. For example, the operating parameter could be adjusted to achieve a desired difference between the measured anisotropy of the first surface and the measured anisotropy of the second surface. Multiple headboxes could be controlled, such as when different headboxes are used to produce different layers of a multi-layer sheet.

  • Publication number: 20140130996
    Abstract: Apparatuses, processes, and systems for implementing techniques for determining characteristics of a papermaking fabric. The techniques include forming a representation of a portion of the surface of the fabric, with the representation showing the knuckles and pockets in the surface. The representation can be formed, for example, in pressure measurement film, in wax paper, or as a photograph. An image is generated from the representation, and the image is analyzed to determine characteristics of the surface of the fabric, such as knuckle sizes and pocket sizes. The depth of pockets in the fabric can also be determined. The techniques can be used in processes for analyzing wear of a fabric, and for obtaining a fabric for making a paper product with a particular three-dimensional structure.

  • Publication number: 20140110871
    Abstract: Partitioning control of the wet end and dry end, by introducing estimates of physical properties such as dry weight: and percent ash at the wire, allows for machine direction (MD) controls to continue during loss of scanner measurements. A mathematical model estimates the controlled, variables, such as dry weight, basis weight, and ash percent at the wire, and these estimated values are then controlled. When scanner measurements resume, parameters in the model are recursively updated to compensate for any model errors and ensure an accurate model. MD controls consist of a cascade set-up where the estimated wire-dry weight or wire basis weight and estimated wire ash percent are controlled by manipulating stock flow and addition of filler to stock. When scanner measurements are available, they become the downstream variables in the cascade control and are controlled by manipulation of the setpoints for the estimated wire weight and ash.
