  • Upper conveyor deck having at least one diverted belt section and a scrap deflector at the diverted belt section and conveyor including the upper conveyor deck
    Patent number: 12589960
    Abstract: An upper conveyor deck includes a plurality of belts each supported by an upstream end pulley and a downstream end pulley which belts are configured to be driven along a closed path having an interior such that a lower run of each of the belts travels in a downstream direction and an upper run of the each of the belt travels in an upstream direction. A first diversion pulley in the interior of at least one of the belts contacts the lower run of that belt, and a diversion guide outside the interior of the belt contacts the belt downstream from the first diversion pulley. A deflecting device at the first diversion pulley is configured to prevent scrap material from becoming pinched between the belt and the first diversion pulley.
