Publication number: 20030113507Abstract: A wrapped absorbent structure that includes two or more absorbent materials to maximize the absorbent functionality of the structure without sacrificing integrity. The structure includes an absorbent core surrounded by an absorbent wrap. The absorbent core is primarily intended to provide absorbent capacity while the absorbent wrap is used to maintain wetness integrity, although the absorbent wrap also provides a considerable amount of absorbent capacity. The absorbent structure is particularly suitable for use in absorbent swimwear.Type: ApplicationFiled: December 18, 2001Publication date: June 19, 2003Inventors: Michael John Niemeyer, Kent Allan Franklin, Robin Kurt Nason, Susan Elaine Shawver, Paul Windsor Estey, Larry N. Barnett

Patent number: 6537401Abstract: This invention pertains to apparatus and methods for creating ultrasonic bonds in sequentially advancing absorbent article workpiece segments, in a bonding nip. The ultrasonic bonding apparatus comprises a frame, anvil support apparatus, horn support apparatus, closure apparatus, a load cell support member, and a load cell. The ultrasonic horn and the anvil roll collectively are mounted and configured such that the ultrasonic horn and the anvil roll can be brought together, via the closure apparatus, to define the nip therebetween. The load cell is mounted to the load cell support member such that force representative of force exerted on the anvil roll at the nip is detected by the load cell. In preferred embodiments, the invention includes outputting information from the load cell and adjusting force in the nip in response to the information received from the load cell.Type: GrantFiled: November 30, 2000Date of Patent: March 25, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jack Lee Couillard, Kent William Abel, Joseph Daniel Coenen, Michael Lee Lohoff, Robin Kurt Nason, Dan James Sorensen

Patent number: 6517650Abstract: This invention pertains to apparatus and methods for intermittently creating ultrasonic bonds in sequentially advancing work piece segments, in a nip. The work piece segments are up to about 0.25 inch thick. The apparatus comprises a frame, anvil support apparatus supporting an anvil, and horn support apparatus supporting an ultrasonic horn. The ultrasonic horn and anvil are collectively mounted and configured such that the ultrasonic horn and anvil can be brought together to define the nip. The frame, anvil support apparatus, and horn support apparatus collectively are sufficiently rigid that the horn and anvil can be brought together with interference levels of about 0.000 to about 0.008 inch at a raised bonding portion in combination with defining sufficient nip pressure to develop ultrasonic bonds in work piece segments passing through the nip. The method comprehends bringing a back-up roll, mounted above the ultrasonic horn, into engagement with the ultrasonic horn, to directly support the horn.Type: GrantFiled: November 30, 2000Date of Patent: February 11, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jack Lee Couillard, Kent William Abel, Joseph Daniel Coenen, Michael Lee Lohoff, Robin Kurt Nason, Dan James Sorensen

Patent number: 6454890Abstract: Bonding apparatus and methods for creating up to full-width ultrasonic bonds in an advancing web. The bonding apparatus comprises a first nip, defined by, in combination, a first set of bonding elements comprising a first rotary ultrasonic horn and a first rotary anvil, and first engagement apparatus bringing the first horn and first anvil into effective bonding engagement with each other. The first horn and anvil being supported from support structure and rotating in common with each other thereby to convey the web through the first nip. The bonding apparatus also comprises a second nip, defined by a second set of bonding elements comprising second separate and distinct horn and anvil, and second engagement apparatus bringing the second horn and second anvil into effective bonding engagement with each other.Type: GrantFiled: November 30, 2000Date of Patent: September 24, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jack Lee Couillard, Robin Kurt Nason, Kent William Abel

Publication number: 20020121128Abstract: A quantitative method of evaluating swimwear for underwater leakage using a mechanical test mannequin, a water tank, a fluorescent bowel movement simulant, and a fluorescence meter. More particularly, a swimwear garment is applied to the mannequin, the fluorescent bowel movement simulant is inserted into the swimwear garment, the mannequin and the swimwear garment are submersed into water within the water tank, and a motion mechanism attached to the mannequin moves the mannequin up and down, thereby simulating typical water play movements. The fluorescence meter can be used to quantitatively determine the amount of leakage of the fluorescent bowel movement simulant from the swimwear garment.Type: ApplicationFiled: December 29, 2000Publication date: September 5, 2002Inventors: Sherry Ann Van Dyke, Robin Kurt Nason, Daryl Steven Meyer, David W. Koenig, Thomas Mathias Kolb, Cynthia Helen Nordness, Marcille Faye Ruman, Faith Eileen Cochrane, Jesse Paul Sorenson, Devertt DeWayne Woolwine, Jerome James Workman

Patent number: 6123792Abstract: This invention relates to apparatus and methods for intermittently bonding a substrate web in fabricating a blank subassembly for an absorbent article. The invention comprises ultrasonic bonding apparatus including an anvil roll, a substrate web thereon, and at least one rotary ultrasonic horn. The substrate web can comprise at least first and second layers of material. The rotary ultrasonic horn, in combination with the anvil roll, ultrasonically bonds intermittent segments of the first and second layers of the substrate web to each other. Such intermittent bonds can comprise end seals for the absorbent articles. The ultrasonic horn and anvil roll are periodically separated from each other to provide the intermittent bonding of the substrate web. An actuator apparatus periodically moves the anvil roll and ultrasonic horn from engaging contact with each other preventing bond formation.Type: GrantFiled: August 14, 1998Date of Patent: September 26, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jeffrey Joseph Samida, Robin Kurt Nason, Daniel Hoo, Chris Lee Heikkinen, Jack Lee Couillard, Chinmay Suresh Betrabet, James Melvin Gaestel, Paul Gordon Klemp
