ABSTRACT:
A device for the destruction of microfilm and similar data carriers with microimage impressions which is designed to shred the data carriers by means of a rotating shredding cutter in the form of a plain milling cutter whose teeth move past a transversely extending stationary cutting edge. A strip feeding unit advances the data carrier strip past this cutting edge along a guide plate, said unit including a driven endless conveying member which forms a conveying gap with the guide plate. A second stationary cutting edge forms a second cutting point behind the first cutting point. The strip feeding unit is self-contained and movable against a spring bias in relation to the main frame and its guide plate, so that a safety switch, responding to such movement, stops the device when too many data carriers are fed into the device simultaneously.
