  • Patent number: 6974514
    Abstract: A method is disclosed for the production of an air-permeable laminate film with a textile surface and elastic and non-elastic regions. At least one film strip that is elastic in the crosswise direction is introduced, as an elastic insert, between two material webs of fiber non-woven fabric having a web width greater than the width of the film strip. The segments of the material webs made of fiber non-woven fabric that are in direct contact next to the insert are connected, forming a non-elastic region of the laminate film. Subsequently, the laminate passes through an ultrasound bonding station, in which the elastic insert is melted by means of point-shaped bonds, while maintaining the substance of the fiber non-woven fabric, thereby connecting the elastic insert with the fiber non-woven fabric cover layers at discrete points and forming air-permeable structures.

  • Patent number: 6969441
    Abstract: In the invention, a method is provided for producing a composite nonwoven fabric. A polymer is extruded into heated continuous filaments, possibly elastic, from the die head to a first chilled roller, wherein the extruder is configured to provide the continuous filaments to the chilled roller in a canted direction that is at a tangent or angle to the surface of the first chilled roller. The filaments are conveyed in a downward direction by way of chilled rollers to a nip. In a next step, the nonwoven web is sprayed with an adhesive and is laminated on the continuous filaments in the nip to form a composite nonwoven fabric. The continuous filaments move vertically downward approximately in line with the lamination process, facilitating automatic re-threading of filaments when they are broken or interrupted in their travel downward onto the chilled rolls.

  • Patent number: 6827806
    Abstract: The present invention provides a method of placing elasticized areas in a nonwoven web construction such as may be suitable for the waistbands or leg openings of disposable absorbent pant garments, cuffs on sleeves of medical garments, or the like. A web, or webs, of extendible nonwoven material which make up the substrate for the elasticized area are printed with an elastic adhesive in its fluid or semi-fluid and untensioned state to provide a tensioning force against distension of the web during wearing of the garment for conformable, well fitting, elasticized cuff areas and may further be used to reinforce biaxially extendible web components such as the backsheet web.

  • Patent number: 6827804
    Abstract: A process for making a pants-type diaper without generation of waste material. 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.

  • Patent number: 6824638
    Abstract: 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.

  • Patent number: 6808582
    Abstract: 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.
