  • Patent number: 5601004
    Abstract: A tire cutting apparatus for severing the tread portion from the sidewall portion of a tire. The severed tread is cut transversely so that it can be extended and placed flat down and used to form a wall, fence or the like. The apparatus includes cutting wheels and roller receivers which are in vertical alignment therewith. Between the cutting wheels is a driver roller which causes the tire carcass to rotate around the roller receivers. A cutter blade is provided to transversely cut the tread portion. The cut is made at the juncture of the tread portion and the upper sidewall portion.
