  • Patent number: 8469192
    Abstract: A method for packaging an absorbent article assembly that includes following the steps. First and second breast milk absorbent pads are fed onto wrapping sheet web. Next, the first breast milk absorbent pad is displaced from a transverse center line toward an upper end by ¼ of a dimension thereof as measured in a longitudinal direction, and the second breast milk absorbent pad is displaced from a transverse center line toward an lower end by ¼ of a dimension thereof as measured in a longitudinal direction. Next, the first and second breast milk absorbent pads are folded back from the upper and lower ends toward the transverse center line. Next, the upper and lower ends of the wrapping sheet web are folded back toward the transverse center line. Next, a joint zone is formed between the first and second breast milk absorbent pads and the pads are cut apart.

  • Patent number: 8450557
    Abstract: The top sheet for an absorbent article has a plurality of fused compressed sections, wherein the fused compressed sections are located on the lowermost side in the thickness direction of the top sheet, and the back side of the top sheet has recesses or low density regions having the lowest density within the top sheet, surrounding the fused compressed sections. The top sheet for an absorbent article having a plurality of fused compressed sections can be produced by a process wherein a top sheet is situated between a member with multiple protrusions and a member with multiple recesses that engage with the multiple protrusions, and the protrusions are pressed into the recesses.

  • Publication number: 20120167736
    Abstract: A cutting system (1) is provided with a cutter roll (2) and anvil roll (3) rotating in opposite directions to each other about substantially parallel axes of rotation. These cutter roll (2) and anvil roll (3) respectively carry a cutting blade (2e) and a receiving blade (3e). A material to be cut which is fed between these cutter roll (2) and anvil roll (3) is cut by the facing cutting blade (2e) and receiving blade (3e). The receiving blade (3e) can elastically displace in a radial direction of the anvil roll (3).

  • Patent number: 8201386
    Abstract: The present invention includes following the steps of: In a first step, first and second breast milk absorbent pads 2(i), 3(i) are fed onto wrapping sheet web 29. In a second step, the first breast milk absorbent pad 2(ii) is fed so as to be displaced from a transverse center line 32 toward an upper end 30 by ¼ of a dimension H thereof as measured in a longitudinal direction Y, and the second breast milk absorbent pad 2(ii) is fed so as to be displaced from a transverse center line 32 toward an lower end 30 by ¼ of a dimension H thereof as measured in a longitudinal direction Y. In a third step, the first and second breast milk absorbent pads 2, 3(iii) are respectively folded back from the upper and lower ends 30, 31 toward the transverse center line 32 in two-ply fashion. In a fourth step, the upper and lower ends of the wrapping sheet web 29 are folded back toward the transverse center line 32.
