  • Patent number: 6427845
    Abstract: A method and apparatus for separating cans or bottles from plastic bags and plastic bag parts, including a frame and a perforated drum operably rotatably attached to the frame. The drum has a circular cross section. A divider member is disposed in the interior of the drum with edges of the divider member being in close proximity to the inside of the drum. A vacuum device is connected to one side of the divider creating a lower pressure section of the drum whereby cans or bottles and plastic bags falling onto the rotating drum causes the plastic bags to attach to the exterior of the drum on the lower pressure section thereof. This allows the plastic bags to be released on the other side of the drum from the pull of the lower pressure as the drum is rotated, by having a low pressure and high pressure side of the drum.
