Abstract: A method of sorting articles having major and minor surfaces such that they normally assume a position presenting one major surface against a support surface and an opposed major surface spaced from said support surface wherein the articles are aligned on a support surface and advanced in a guided single file past a discriminating means which alters the path of advance of those articles having a first given orientation of its major surface relative to the guide means. The articles of the opposite major surface orientation relative to the guide means support surface are thus segregated. Both segregated groups of articles can be merged following their orientation to a like major surface relationship to a reference support surface.A turntable imposes centrifugal forces on the articles to be sorted to pass them to a tangential guide chute in single file.
