  • Patent number: 5718030
    Abstract: A dry abrasive delabeling apparatus for both plastic and glass bottles, sometimes called a label stripper, in which the bottles are fed by an in-feed starwheel to a circular starwheel which rotates the bottles slowly. Within the starwheel are wire bristle brushes rotating at a high speed against the bottles to flick off paper, foil, or plastic from the label on the bottle while restraining the bottle in close contact to the ends of the wire bristle by means of a rubber bladder to press against the bottles. The bottles are held against the wire bristles while the bottles are rotated as they are held against the bladder. The debris is vacuumed away from the apparatus.
