Abstract
The invention relates to a method and apparatus for opening packaged articles, particularly packs and cartons of cigarettes, in which such items are ripped open and broken apart sufficiently to allow the contents, e.g. tobacco, to be separated and recovered. The apparatus aspects of this invention involve a ripper fan, a recycling air leg, and a cyclone separator from which the materials are recovered for further processing.
