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.
