  • Patent number: 4901981
    Abstract: Device for removing a staple from a stapled bundle of sheets by moving the bundle over a supporting element past a staple removing strip. The strip extends above the supporting element at a small acute angle therewith and is fixed to an arm which is rotatably mounted on a shaft positioned at the side of the strip facing away from the acute angle and below the supporting element. The strip is moved upwards when a stapled bundle of sheets, with the legs of the staple facing downwards, is fed between the supporting element and a wedge-like tapered end of the strip, which end presses onto the supporting element. When in this way the staple is positioned in front of the wedge-like tapered end of the strip, the bundle is pulled towards the strip, the end of the strip penetrates between the crown of the staple and the bundle and the staple thereafter is pulled out of the bundle. The pulled-out staple drops in a receiving tray formed beneath the supporting element.
