Patents by Inventor James S. Rugowski

James S. Rugowski 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).

  • Patent number: 5593545
    Abstract: A method for making uncreped throughdried tissues is disclosed in which the dried tissue sheet is fully supported by a fabric up to the reel. This method eliminates the open draw between the throughdryer and the reel and thereby eliminates sheet breaks normally associated with such open draws. In addition, the machine direction strength of the sheet can be reduced since the added strength is not needed to traverse the open draw normally present in current processes. Reducing the MD strength in turn enables the production of more square, less stiff sheet, which improves the tactile properties of the product.
    Type: Grant
    Filed: February 6, 1995
    Date of Patent: January 14, 1997
    Assignee: Kimberly-Clark Corporation

  • Patent number: 4967805
    Abstract: A forming fabric for use in papermaking machines for making tissue products in which the fabric is a three-ply fabric. The upper ply has its machine direction (MD) filaments arranged in groups so that wide channels are provided through the ply between the groups and narrow channels are provided through the ply within the groups. Cross direction (CD) filaments in the upper ply provide CD knuckles spanning across the channels to provide a gridwork for supporting fibers separated from the water of the slurry deposited on the forming fabric, the fibers having a greater density in bands overlying the wide channels than in the intermediate bands overlying the narrow channels. The lower ply is a porous fabric which further controls the flow of the water discharged from the pulp through the upper ply. The two plies are interconnected by integrated binder filaments which cooperate to maintain the groupings of the MD filaments in the upper ply.

  • Patent number: 4942077
    Abstract: Creped tissues having improved perceived softness and appearance are made from tissue webs having at least a machine direction broken line pattern of individual densified areas containing higher mass concentrations of fibers. The broken line pattern of densified areas creates a pleasing appearance and influences the creping to provide a more uniform crepe and hence improved tissue softness.
