Patent number: 5948507Abstract: Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form.Type: GrantFiled: July 13, 1998Date of Patent: September 7, 1999Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Fung-jou Chen, Jeffrey Dean Lindsay

Patent number: 5693403Abstract: High sheet count rolls of spot-embossed, soft bathroom tissue suffer from embossing patterns becoming pressed out by the high winding tension necessary to confine the size of the roll to a diameter of about 5 inches. This size is necessary in order for such high sheet count rolls to fit within the bathroom tissue dispensers found in most households. However, by embossing the tissue between a resilient back-up roll and an engraved embossing roll having short male embossing element heights of only from about 0.005 to about 0.035 inch, the tissue sheet becomes simultaneously calendered, which lowers the sheet caliper (as measured under a compressive load). Because of the resulting lower caliper, the embossed sheet can be wound into the required roll size with less tension on the sheet, such that the embossing pattern for tissue sheets within the roll remains well defined.Type: GrantFiled: March 27, 1995Date of Patent: December 2, 1997Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Joseph William Brown, Jerome Steven Veith, Thomas Allan Eby, Joel James Banda

Patent number: 5490902Abstract: A method and apparatus for embossing paper products, such as paper towels or toilet tissue, in which the tensile strength extending in the machine direction is modified such that after embossing, the tensile strength in the machine direction is more nearly equal to the tensile strength in the cross-machine direction. During embossing, selected portions of the embossed pattern are embossed more deeply to fracture fibers extending in the machine direction, thereby modifying the tensile strength in the machine direction. An improved paper product is thereby formed having a machine direction:cross-machine direction tensile strength ratio which is more closer to 1:1.Type: GrantFiled: October 18, 1994Date of Patent: February 13, 1996Assignee: James River Corporation of VirginiaInventor: Galyn A.
