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