Patents by Inventor Daniel Robert Sprangers

Daniel Robert Sprangers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Through-air drying apparatus and methods of manufacture
    Patent number: 10240292
    Abstract: Unlike conventional through-air drying processes the instant invention utilizes at least two through-air driers where the first dyer is at least partially encircled by a first through-air drying fabric and the second dyer is at least partially encircled by a second through-air drying fabric. By providing each through-air dryer with its own fabric the overall drying performance may be increased. Additionally, in certain embodiments, the first and second fabrics may be different to optimize both the drying performance and/or tissue product properties.
    Type: Grant
    Filed: February 29, 2016
    Date of Patent: March 26, 2019
    Assignee: KIMBERLY-CLARK WORLDWIDE, INC.
    Inventors: Mark John Hassman, Peter John Allen, Frank Stephen Hada, Robert James Seymour, Richard Allen Zanon, Richard Mark Hansen, Nathan John Haiduk, Samuel August Nelson, Daniel Robert Sprangers, Paul Timothy Baker

  • Surface treating tissue webs via patterned spraying
    Patent number: 7988828
    Abstract: Tissue webs, such as are useful for making bath tissue, can be surface-treated in a pattern with selected papermaking chemicals, such as debonders and strength agents, to selectively improve the directional properties of the resulting tissue product, particularly the cross-machine direction strength properties. The pattern can be applied to the tissue sheet by spraying the selected chemical outwardly through a pattern of open areas in the shell of a rotating hollow roll, where the pattern of open areas corresponds to the desired pattern of chemical deposited on the surface of the tissue web.
