Patent number: 10201458Abstract: 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.Type: GrantFiled: November 3, 2008Date of Patent: February 12, 2019Assignee: ESSITY HYGEINE AND HEALTH AKTIEBOLAGInventors: Ulrika Carlson, Hans Een, Margareta Wennerbäck

Patent number: 9060902Abstract: 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.Type: GrantFiled: October 30, 2008Date of Patent: June 23, 2015Assignee: SCA HYGIENE PRODUCTS ABInventors: Inge Gabrielii, Ulrika Carlson, Hans Een

Patent number: 8652113Abstract: 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.Type: GrantFiled: October 30, 2008Date of Patent: February 18, 2014Assignee: SCA Hygiene Products ABInventors: Inge Gabrielii, Ulrika Carlson, Hans Een, Maria Bogren, Sofia Hermansson

Patent number: 8449519Abstract: 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.Type: GrantFiled: December 20, 2007Date of Patent: May 28, 2013Assignee: SCA Hygiene Products ABInventors: Hans Een, Marcus Lehto, Ulrika Carlson

Patent number: 8439813Abstract: A method of manufacturing a top sheet material or back sheet material for use in the manufacture of disposable absorbent articles including the steps of: a) splitting a continuous first web of sheet material having substantially straight side edges into a second and third continuous web by an alternating concave-convex cutting line cut in a longitudinal direction along the continuous first web, the cutting line being distanced from both side edges of the continuous first web; b) shifting the second continuous web in a lateral direction in relation to the third continuous web so that the substantially straight edges of the second and third continuous webs are parallel to and adjacent to each other and longitudinally shifting the second continuous web so that the series of concave edge portions and the series of convex edge portions of the second and third continuous webs are longitudinally aligned with each other; c) directly or indirectly joining the substantially straight edges of the second and third continType: GrantFiled: June 4, 2009Date of Patent: May 14, 2013Assignee: SCA Hygiene Products ABInventors: Lucas Bäck, Ulrika Carlson

Patent number: 8282615Abstract: An absorbent article includes a front region (2), a back region (3) and a crotch region (4) there between. The article further includes substantially longitudinally extending inner (12) and outer (13) leak barriers alongside each side of the absorbent core (9). The inner and outer leak barriers are spaced from each other in the transverse direction (x) of the article. The inner leak barriers (12) extend at least along the part of the crotch region (4) having the narrowest width (w1) in the transverse direction (x), and along a length (b) of at least 5 cm, and the outer leak barriers (13) extend along at least a part of the front region (2) and/or back region (3) of the article, while at least a part of the crotch region (4) along which said inner leak barriers (12) extend is free from raised outer leak barriers (13).Type: GrantFiled: April 11, 2007Date of Patent: October 9, 2012Assignee: SCA Hygiene Products ABInventors: Hans Een, Jan Wästlund-Karlsson, Ulrika Carlson, Sue Uner

Patent number: 8246595Abstract: An absorbent article having a front region, a back region and a crotch region there between, said article has substantially longitudinally extending leak barriers, each of said leak barriers having a free laterally inward elasticized side and a laterally outward side, the elasticized side of the leak barrier being raised from the inner cover of the absorbent article. The crotch region along a length of at least 2 cm, preferably at least 5 cm and more preferably at least 10 cm, in longitudinal direction is free from raised leak barriers, while raised leak barriers are present in the front and/or back regions of the article.Type: GrantFiled: April 5, 2006Date of Patent: August 21, 2012Assignee: SCA Hygiene Products ABInventors: Ulrika Carlson, Hans Een, Jan Wästlund-Karlsson
