  • Publication number: 20240277529
    Abstract: A method for continuously producing disposable pant-type articles from webs moving in a machine direction, the method including attaching a non-elastic crotch web between a tensioned elastic front panel web and a tensioned elastic rear panel web to form a coherent chassis web of interconnected precursor articles and attaching a pair of stretched crotch elastic members to the chassis web in each precursor article with the crotch elastic members being arranged in a cross machine direction, whereafter leg cuts are formed in the chassis web between the precursor articles, the chassis web is folded along a fold-line extending in the machine direction, first and second side seams are formed in each precursor article, along dividing lines between the precursor articles, the side seams being formed from the aligned waist edges of the precursor articles, to the leg cuts, and finally severing individual pant-type articles from the chassis web.

  • Publication number: 20240252368
    Abstract: A disposable pant-type article including a front body panel and a rear body panel, each being elastically stretchable in a transverse direction, and a crotch region being located between a front panel crotch edge and a rear panel crotch edge. The article has first and second leg edges, each leg edge constituted by a front leg edge section, a rear leg edge section, and a crotch leg edge section. Each front leg edge section has an inner point located at a greater distance from a side seam than from a longitudinally extending centre line, the inner point being closer to the front waist edge than an outer point on the front leg edge section. Each crotch leg edge section has an intermediate point located between the front and rear crotch edges which is closer to the longitudinal centre line than a front endpoint of the crotch leg edge section.

  • Publication number: 20240245557
    Abstract: A disposable pant-type article including a front body panel and a rear body panel, each being elastically stretchable in the transverse direction, and a crotch region being located between a front panel crotch edge and a rear panel crotch edge. The article has first and second leg edges, each leg edge constituted by a front leg edge section being arranged in the front body panel, a rear leg edge section being arranged in the rear body panel; and a crotch leg edge section being arranged in the crotch region. A pre-tensioned first crotch elastic member is arranged extending in the longitudinal direction along the first leg edge and a pre-tensioned second crotch elastic member is arranged extending in the longitudinal direction along the second leg edge. The crotch leg edge section of the leg edges extends completely or partly in the respective crotch elastic member.

  • Publication number: 20240216186
    Abstract: Pre-tensioned first and second crotch elastic members are arranged extending in the longitudinal direction along the leg edges in the crotch region, the leg edges in the crotch region extending partly or fully in the corresponding crotch elastic member. The crotch region is generally hourglass-shaped with a narrow intermediate portion. The crotch elastic members have first side edges at least partly coinciding with the corresponding leg edge in the crotch region. A distance as measured in the transverse direction between the first side edge of the absorbent core and the first side edge of the first crotch elastic member and a distance as measured in the transverse direction between the second side edge of the absorbent core and the first side edge of the second crotch elastic member varying with at most 30 millimetres along a full length of the crotch elastic members.
