Patent number: 11634293Abstract: The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.Type: GrantFiled: July 26, 2022Date of Patent: April 25, 2023Assignee: Kimberly-Clark Worlwide, Inc.Inventors: Ryan A. Petras, Matthew W. Trautschold, Mark G. Dollevoet, Vivek M. Karandikar, Julie A. Hansen, Walter F. Montgomery, Antwain Taylor, Kevin B. Sartain, Justin P. Stergar

Patent number: 9540202Abstract: Registration and inspection systems and methods for use on a winder are disclosed. The systems and methods include scanning a region proximate a winding module with one or more sensors to determine a product defect. The product defect is then associated with a winding process parameter, such as percent roll build information or the identity of the particular sensor to first detect the defect. The winding process parameter is used to classify the defect into one or more defect profiles. The defect profiles can be based at least in part on segmenting the roll build of a web onto a winding module into a plurality of inspection windows and segmenting a plurality of sensors into a plurality of inspection sensor segments.Type: GrantFiled: March 19, 2014Date of Patent: January 10, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Brett Schoenberg, Mark Gary Dollevoet, Jeffrey George Skarda, Matthew Robert Wilson, Kevin B.

Patent number: 9486932Abstract: An apparatus for perforating sheet materials is disclosed. The apparatus includes a perforation blade that defines a plurality of teeth for perforating sheet materials, such as tissue products. Each tooth on the perforation blade is defined by a pair of opposing side walls. The teeth are separated along an edge of the perforation blade by a plurality of recesses. In accordance with the present disclosure, the side walls have a non-zero angle with respect to the length direction of the blade. In one embodiment, each recess can have a slanted U-shape such that all of the side walls are parallel. In an alternative embodiment, the recesses can have a V-shape such that adjacent side walls extend in divergent directions. Perforation blades made according to the present disclosure prevent snagging and picking when a material is perforated.Type: GrantFiled: April 16, 2014Date of Patent: November 8, 2016Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Leo Baggot, Walter F.

Patent number: 7079263Abstract: A measurement system for measuring a parameter of a log is provided. A measuring device produces an emission in a direction of the log. A portion of the emission measures the parameter, such as log diameter, and communicates the diameter to the measuring device, which in turn communicates the diameter to a controller to selectively adjust converting equipment to vary the diameter.Type: GrantFiled: June 14, 2002Date of Patent: July 18, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Kevin B.

Patent number: 6732452Abstract: A paper web drying apparatus and process is provided in which the heated air drying medium is replaced with between 10 percent to 100 percent of live steam. The addition of a steam component to the drying medium provides for a higher drying temperature to be supplied to the wet moving web. The introduction of live pressurized steam contributes to the load of force of the drying medium, thereby decreasing the energy requirements of blower motors. The introduction of pressurized live steam also lowers the free atmospheric oxygen content of the drying medium which reduces the burning or scorch hazard associated with high temperature drying of a cellulose web.Type: GrantFiled: December 21, 2001Date of Patent: May 11, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Philip S. Lin, Ronald F. Gropp, Kevin B. Sartain
