A support table (26) is attached to the frame (14) for receiving a bale of used paper product (28) that is held together by banding material (30). As the bale (30) is moved past the band breaking blade (42), a band retention notch (68) engages a band (30) and by stretching it, breaks the band (30). Once a band (30) is broken, an extensible/retractable band catch (18) extending from the surface of the mandrel (16) engages the band (30) and facilitates the winding of the band (30) around the mandrel (16). Once all bands (30) have been removed from the bale (28), the band catch (18) is retracted to a position within the mandrel (16), a protective hood (47) is pivoted away from the mandrel (16), the mandrel (16) is elevated to meet the mandrel cleaning plate (36) and the cleaning plate (36) is moved axially along the mandrel (16), sweeping the bands (30) off a free end of the mandrel (16). This process is repeated to remove bands from other surfaces of the bale, thereby releasing the waste paper in preparation of processing.</p> |
