Patent number: 8663420Abstract: 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.Type: GrantFiled: April 14, 2011Date of Patent: March 4, 2014Assignee: Zuiko CorporationInventors: Masaki Nakakado, Yuzo Ichiura, Satoshi Tanaka, Ikuo Tachibana

Publication number: 20040102756Abstract: 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.Type: ApplicationFiled: November 17, 2003Publication date: May 27, 2004Inventors: Yuzo Ichiura, Masaki Nakakado, Kazutoshi Makimura, Syuhei Kurata

Patent number: 6604623Abstract: 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.Type: GrantFiled: January 23, 2002Date of Patent: August 12, 2003Assignee: Zuiko CorporationInventors: Isamu Sumi, Yuzo Ichiura, Hiromi Mae
