  • Patent number: 11033439
    Abstract: An elastic laminate including a first nonwoven layer, a second nonwoven layer, and a plurality of elastic strands arranged in parallel with one another between said first and second nonwoven layers is disclosed, as well as a process for the production of the laminate. The elastic laminate includes elastic strands that are stretched and individually coated with an adhesive. The first and second nonwoven layers are attached to the stretched elastic strands to provide a corrugated elastic laminate when the elastic strands are relaxed. At least one of the nonwoven layers is attached to the strands at distinct adhesive bonding points in a repeating predetermined pattern in a lengthwise direction along the strands to form a predetermined corrugation pattern, and the nonwoven layers are substantially free of adhesive, except in the adhesive bonding points where the layers are attached to the elastic strands.

  • Patent number: 10449098
    Abstract: A wearable disposable absorbent article includes a front panel, a back panel, and a crotch panel bridging and at least partially overlapping the front and back panels. A backsheet of the crotch panel has a laminate structure including a liquid barrier sheet and a nonwoven layer arranged on top of each other. The liquid barrier sheet extends over the entire length of the crotch panel and further over at least a portion of each of the front and back panels. The nonwoven layer extends at least over the entire length of the crotch panel but not over a length of more than 40 mm over each of the front and back panels. The width of the nonwoven layer is smaller than the width of the liquid barrier sheet.

  • Patent number: 10201458
    Abstract: A method for producing pant-type articles having a waist-encircling portion and leg-encircling portions. The method includes forming a chassis structure and at least one elastic panel being formed by providing a first web, which is an elastic web including at least one layer of an elastic material. The first web is stretched at least 70% in at least one direction. The stretched first web is bonded while the first web is held in the stretched state to a second web. The second web includes at least one layer of an elastic or non-elastic material, and the bonded first and second webs form an elastic composite web. The elastic composite is relaxed in the at least one direction by at least 4% of the stretched length of the stretched first web. The chassis structure is assembled from chassis components including the stretched and relaxed composite web.

  • Patent number: 9060902
    Abstract: A disposable absorbent article intended to be worn around the waist of a wearer. The article includes a chassis having a front portion, a back portion, and a crotch portion there between, and optionally includes a waistband. A printed tag is arranged on the inner wearer facing side of the chassis in at least one of the front portion, back portion or the waistband. The tag has a Surface roughness or Friction according to Kawabata which differs at least 10% from the Surface roughness or Friction respectively according to Kawabata of the surrounding area of the chassis to which the tag is attached. This enhances the possibilities to localize the tag by the fingertips and thus make it possible for a person with poor eyesight and under bad light conditions to differentiate between the front and back of the article.

  • Patent number: 8652113
    Abstract: A disposable absorbent article intended to be worn around the waist of a wearer includes a chassis having a front portion, a back portion, and a crotch portion there between, and optionally a waistband. A printed tag is arranged on the inner wearer facing side of the chassis in at least one of the front portion, back portion, and the waistband. The tag has at least one first area which is fixedly attached to the chassis and at least one second area which is unattached. The first fixedly attached area covers an area of at least 5% of the total area of the tag and the second unattached area has a length extending along a side edge of the tag of at least 5 mm and a width of at least 1 mm. The tag as described makes it easier to differentiate between the front and back of the article.

  • Patent number: 8545654
    Abstract: A method for producing pant-type absorbent articles, each article including a chassis structure having at least one elastic panel and an integrated absorbent core component, the method including a continuous pant-forming process including forming the chassis structure and incorporating the absorbent core component into the chassis structure. The at least one elastic panel is formed by a) separately producing a two-layer laminate having a first non-elastic fibrous nonwoven web and an elastic film, b) activating the two-layer laminate by incremental stretching in at least one activation direction to render the two-layer laminate (elastically stretchable, c) stretching the activated two-layer laminate by 35-200% in the activation direction, d) introducing the two-layer laminate in the pant-forming process, and e) laminating the elastic film of the stretched two-layer laminate to an elastic or nonwoven chassis component. An absorbent pant-type article produced in accordance with the method.

  • Patent number: 8449519
    Abstract: A seam joining together at least two web materials in an overlapped manner by ultrasonic welding, heat bonding or the like, in a bonding pattern, which includes comprising a first bonding pattern and at least one second bonding pattern extending in a longitudinal direction along and adjacent at least one side edge of the overlapped portion. The bonded area of the second bonding pattern occupies more than 30% of the combined bonded area of the first and second bonding patterns. The bonding elements of the first bonding pattern have a mean area that is at least 2 times the mean area of the bonding elements of the second bonding pattern. The contact area of the bonding pattern, as seen in transverse direction of the seam, is between 10 and 30% of the width of the bonding pattern at any given point along the length of the bonding pattern.
