ABSTRACT:
Systems, methods, and devices for preventing the misalignment of sheet material in hoppers adapted to feed sheet material to disk separators are disclosed. In one aspect, a floating backguide is provided. The floating backguide moves independently of the hopper with which the backguide is associated. The floating backguide may be pivotally mounted at a first end and free to deflect to a limited degree at a second end. In one aspect, the deflection of the second end is limited in the horizontal direction by two stationary bars and in the vertical direction by two stops. The vertical deflection of the second end of the backguide may also be limited by a resilient material, for example, a spring or an elastomer. A method for feeding sheet material to a disk separator using a floating backguide is also provided.
