  • Patent number: 11857399
    Abstract: Disclosed is a method for transferring cut-out nonwoven material members, the method including feeding a continuous web of a nonwoven material towards cutter and anvil roll, passing the continuous web between the cutter and anvil roll, the cutter roll having knives protruding from the circumferential surface, the knives having an edge with a first outline shape seen in a circumferential direction of the cutter roll, cutting the continuous web thereby forming cut-out nonwoven material members having a second outline shape corresponding to the first outline shape of the respective edge of the knives, and transferring the cut-out members to a vacuum roll having an outer circumferential surface that includes a plurality of vacuum ports arranged in a pattern, the pattern including pattern units each having a third outline shape, the pattern units fitting within the second outline shape of the cut-out members.

  • Patent number: 11395771
    Abstract: The present invention relates to a disposable hygiene article comprising a pair of curved compression lines in a rear portion of the article. The article has a core with a first region which has its narrowest width (M) in the transverse direction (x) in a front portion or at a location of a transition between the front portion and a crotch portion of the article. The absorbent core in the rear portion comprises the first (L1, R1) and second (L2, R2) pairs of rear compression lines, which extend in a longitudinal direction (y) between respective front and rear endpoints. A transverse distance (G3min) separates the rear endpoints of the pair of compression lines whilst a second, larger distance (G3max) separates the front endpoints of the compression lines.

  • Patent number: 11141323
    Abstract: A disposable hygiene article having an absorbent core with a first region which has its narrowest width (M) in the transverse direction (x) in a front portion or at a location of a transition between the front portion and a crotch portion of the article. The absorbent core comprises a high-density first region and a low density second region. The absorbent core in the crotch region has first and second rear compression lines. The compression lines mutually diverge in a direction towards the core front edge. Each line has a diverging angle (?2; ?3) of from 15-60° with respect to a centre line (A). The second region has an average density which is at least 20% lower than the average density of the first region.
