  • Patent number: 5102057
    Abstract: The present invention is directed toward an apparatus for compressing plastic waste for the purposes of minimizing space, maximizing manageability and otherise improving the logistics of household recycling. The claimed invention is an electrically powered machine that rotates a plurality of converging, tapered cylinders. Each cylinder has chisel pointed teeth arranged in a helical pattern along the surface of each cylinder. Once a piece of plastic material is placed between the cylinders, the motor is turned on. The cylinders all rotate in the same direction. The pointed teeth on the cylinders grab the plastic material, forcing it deeper between the converging cylinders. The rotation of the cylinder, with the protruding teeth, cause the plastic material to twist as it is pulled downward. Eventually, the plastic material is passed through the bottom of the converging cylinders, wherein the plastic material is oriented in a tightly compressed and twisted cylindrical form.
