  • Patent number: 8663420
    Abstract: A rotation device includes an endless guide that defines a continuous circular path, a plurality of moving sections whose movement is guided by the endless guide, and a plurality of pads. Each pad is capable of carrying an article thereon, and each pad is mounted to a respective moving section. A method for producing a worn article using such a rotation device includes the following steps: (i) rotating a fixed pivot point about a first axis where a link connects the pivot point to the moving section; (ii) guiding a moving section along the path defined by the endless guide, where the endless guide has a second axis parallel to but offset from the first axis; (iii) receiving an article by the pad, where the rotating and guiding steps change a spacing interval between adjacent pads; and (iv) releasing the article from the pad after the spacing interval has changed.

  • Publication number: 20110212818
    Abstract: A method for producing a wearing article of the present invention includes the steps of: supplying an elastic member; stretching the elastic member; placing the stretched elastic member so that the elastic member spreads across a plurality of first webs divided in a transport direction; making a part of a second web loose in the transport direction while transporting the second web, thereby forming a loose portion; placing the first webs, on which the elastic member is disposed, on non-loose portions before and after the loose portion of the second web; and cutting the elastic member between adjacent first webs of the plurality of first webs.

  • Publication number: 20040102756
    Abstract: An absorbent article (1) includes a cuff (30) and a liquid-holding absorbent (5). The cuff (30) is provided on a surface of a sheet (3) covering the liquid-holding absorbent (5). The cuff (30) is obtained by folding the sheet, which faces a surface of a body of a wearer, and folding back the sheet so as to form a two-folded shape. An adhesion section (37) for keeping the two-folded shape of the cuff is provided at least near a base portion of the cuff.

  • Patent number: 6604623
    Abstract: With an article transfer apparatus 1 of the present invention, when a negative pressure is applied on an air outlet 20 in a non-attracting state, the amount of air that is sucked through suction holes 6 in a front attracting section 2f is greater than the amount of air that is sucked through suction holes 7 in a rear attracting section 2b. Therefore, the suction amount through the front attracting section 2f is increased while reducing the suction loss of the attracting pad 2, thereby improving the reliability of the attraction operation.
