Abstract: A shredding machine for domestic or office use having a feed passage 3 leading to a cutting mechanism 10, 11 powered by an electric motor, has a thickness measuring device 15 for measuring the thickness of bundles of paper fed through the feed passage and the machine is controlled by a microprocessor which receives signals from the thickness measuring device and prevents the cutting mechanism from being energized if the thickness measured is above a threshold determined by the microprocessor. The microprocessor varies the threshold in accordance with electrical supply voltage, the electric motor temperature and the electric current drawn by the motor during a previous shredding operation, so that the maximum thickness the shredder will accept can be reduced automatically when motor temperature increases or as the effectiveness of the machine deteriorates throughout its working life.

Abstract: A shredder has cutter elements for destroying articles (paper) and a feed mechanism for advancing paper from a stack in a tray into cutters for shredding. The feed mechanism has a feed member provided adjacent to the tray with an elastic arm for engaging and disengaging the stack.

The elastic arm can include a protruding tip that is inserted into the stack. The tray includes a curved feed bed to assist in feeding paper into the cutters and deforming the elastic arm. A pivot arm can also move the feed member relative to the tray (e.g., vertically). A disengagement mechanism can hold the feed mechanism in an inoperable feeding position when a drawer or tray is moved into an open position.
