The pants-type diaper is composed of a body fluid absorbent pad member curved in a U-shape, a front waist member and a rear waist member extending around front and rear waist-halves, respectively. The front and rear waist members are obtained by feeding first and second elastic members in parallel to each other in a machine direction so as to describe substantially sinusoidal curves, respectively, securing these elastic members to one surface of a web fed in the machine direction and then transversely bisecting the web between the first and second elastic members. The first and second elastic members are symmetric to each other about a center line bisecting the web but phase-shifted with respect to each other in the machine direction by half a cycle of the substantially sinusoidal curve.Type: GrantFiled: March 11, 2002Date of Patent: December 7, 2004Assignee: Uni-Charm CorporationInventors: Toshifumi Otsubo, Hiroki Yamamoto

Patent number: 6824638Abstract: Methods of forming composite graphic images on a substrate using a plurality of films that are applied and registered with each other under tension are disclosed. The films may include registration marks distributed along their lengths and those registration marks can be used to vary the tension under which the films are dispensed during application to a substrate. By detecting the registration marks on a film already applied to a substrate and detecting corresponding registration marks on a film being dispensed and applied to the substrate, registration between the different portions of the composite image on the different films can be maintained over the length of the films and, therefore, the length of the resulting composite image. That registration is controlled by varying tension of the film being applied.Type: GrantFiled: July 27, 2000Date of Patent: November 30, 2004Assignee: 3M Innovative Properties CompanyInventors: Conrad V. Anderson, Brett A. Behnke, John R. David, Ronald S. Steelman

Patent number: 6808582Abstract: A method of applying leg elastics to absorbent garments involves varying the number and position of feed nips and idler rolls and optimizing the tension between multiple elastic members. The elastic members are bonded to a substrate with variable tension. More particularly, higher tension is provided in the areas of the garment where greater gasketing pressure is required, while lower tension is provided in areas where greater comfort is desired and high gasketing pressure is not needed. Furthermore, each elastic member may vary in degrees of tension from the other elastic members. The resulting garments have optimized comfort, fit and containment about the leg openings.Type: GrantFiled: March 17, 2003Date of Patent: October 26, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Robert Lee Popp, Joseph D.

Patent number: 6803113Abstract: A multilayered packaging film having good antifog performance that is suitable for use in food packaging. The multilayered film comprises an outer film attached to an inner film, which outer film is a combination of a first nylon layer, an ethylene vinyl alcohol layer attached to a surface of the first nylon layer and a second nylon layer attached to the ethylene vinyl alcohol layer. The inner film is a combination of a third nylon layer having a silicone oil on a first surface of the third nylon layer, and a sealant film on a second surface of the third nylon layer, attached either directly or via an intermediate adhesive layer. An antifog composition is either contained within the sealant film or is coated on a surface of the sealant film opposite the third nylon layer. The silicone oil effectively blocks the migration of the antifog composition into an adjacent nylon layer when the multilayered film is stored in roll form.Type: GrantFiled: September 13, 2002Date of Patent: October 12, 2004Assignee: Honeywell International Inc.Inventors: Simon J.
