Patent number: 6344111Abstract: A novel paper article, a method of making a paper product, and an embossing roll are disclosed for providing a paper surface region having a minority of fiber to fiber bonds broken in the paper surface region to a depth less than about 0.02 mm from the paper surface. In one aspect, the roughened embossing roll includes protuberances or depressions sized at less than about 0.1 mm. In one aspect, the roughened embossing roll includes protuberances or depressions adapted to produce paper product surface deformations in the paper surface, wherein the paper product surface deformations are invisible to an unaided human eye. The present invention provides a paper product having higher perceived softness while maintaining tensile strength.Type: GrantFiled: April 1, 1999Date of Patent: February 5, 2002Assignee: Kimberly-Clark Wordwide, Inc.Inventor: Lee Delson Wilhelm

Patent number: 6343420Abstract: The method includes sliding a first shim onto the support shaft until it abuts a shoulder. The first shim has a predetermined thickness. A bearing is then slid onto the tapered surface and a lock nut is tightened onto the threaded portion of the shaft. As the lock nut contacts the inner race of the bearing it causes the inner race to contact the first shim and also to radially expand outwardly, thereby preloading the bearing. The outer race of the bearing is then connected to a motor and the motor is operated at a predetermined, constant speed. The torque required to rotate the outer race of the bearing is measured and compared to a predetermine torque range to determine if the bearing is precisely preloaded.Type: GrantFiled: November 15, 1999Date of Patent: February 5, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Mark William Beduhn, Jimmy Harrell Howard, Jr.

Patent number: 6319347Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to transferring discrete parts to a continuous web, whether paper, film, composite, or the like. Specifically, the invention relates to methods and apparatus for taking discrete parts from a source in a taking zone, optionally taking the discrete parts as components of a continuous web, onto a transport head on a transfer assembly, severing the discrete parts from the continuous web if received as part of a continuous web, rotating the transfer assembly about a first axis and correspondingly rotating the transport head about a second axis radial to the first axis, to thereby present the discrete parts to a receiver in a transfer zone, and transferring the discrete parts to the receiver in the transfer zone.Type: GrantFiled: January 31, 1995Date of Patent: November 20, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Gregory John Rajala, Paul Martin Niemi, Daniel James Oshefsky

Patent number: 6318727Abstract: An apparatus is disclosed for maintaining a fluid seal with a moving substrate. The apparatus includes an enclosure and a cap. The enclosure has a first surface and a second surface with the first surface being in sealing contact with the moving substrate. The cap seals off the second surface of the enclosure. The cap is secured to the enclosure at at least two spaced apart locations and has a non-secured portion that is capable of deflecting independently of the enclosure. The apparatus further includes means for introducing a pressurized fluid into the enclosure. The pressurized fluid creates a net force on the enclosure of zero and a force on the cap which causes a portion of the cap to deflect. The deflection of the cap allows the first surface of the enclosure to remain in sealing contact with the moving substrate.Type: GrantFiled: November 5, 1999Date of Patent: November 20, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Frank Stephen Hada
