ABSTRACT:
A paper shredder includes a lower cabinet and an upper hood for covering the cutting rollers, The hood has a supply duct for material to be cut which conically narrows toward the cutting roller intake gap, The supply duct has an inlet opening whose upper edge in vertical projection is located laterally offset relative to the cutting roller intake gap, The supply duct for the material to be cut has a funnel-shaped cross section and a bottom side of the supply duct extends initially approximately horizontally and is then arc shaped and leads into the essentially vertically directed cutting roller intake gap. A duct wall extending from an upper side of the hood and forming the upper edge of the inlet opening of the supply duct is formed by a ledge member which is a separate component,
