摘要: A method and apparatus for selectively orienting an article (28) can include a selective indexing of movable carriage (94) between first position at least second position, thereby providing selected face-alignment datum surface (74) the article. In particular aspects, be configured to provide first, twist displacement article, second, with directionally opposite displacement. another aspect, wheel (120). further one set twist-belts (66) connected (94).
