ABSTRACT:
A method and apparatus for rupturing refuse carrier bags to expose the potentially salvagable materials therein is disclosed. A transport tube is provided with an inlet end having an upper circumferential portion cut away to receive carrier bags placed therein and an outlet end having an opening for expelling the contents of the carrier bags. A screw impeller means is rotatably supported in the transport tube. Drive means are provided for rotating the screw impeller within the transport tube to advance the carrier bags from the inlet end toward the outlet end. A sleeve means is formed is about the screw impeller between the inlet end and outlet end of the transport tube. The sleeve is slightly larger in diameter than the screw impeller. The upper portions of the carrier bags engage the sleeve and are thereby prevented from being further advanced through the transport tube. The screw impeller then ruptures the carrier bag to expose the contents therein.
