Abstract
A file shredder has an integrated unit for automatic feed of sheets of paper or similar materials. An upper device part contains a cutting mechanism, at least one drive, and a control device. A feed shaft leads from the top of the upper device part, and a secondary channel leads from a chamber-like intake opening disposed on the side, to the cutting mechanism. A hinged lid pivotable about an axis is assigned to the chamber-like intake opening, and the upper device part sits on a lower device part. A barrier is disposed near the front, lower edge of the face surface of the hinged lid, and along this edge. The barrier rests on the top sheet of the stack of sheets laid into the chamber-like intake opening, and removes any objects still adhering to this sheet, particularly staples, when the sheet is drawn in toward the cutting mechanism.
