ABSTRACT:
A microfilm destructing apparatus with a case and with a feed shaft disposed at the case for feeding of one or possibly more film cards along a cutter plate to a rotating milling cutter, which disintegrates the film card into fine particles; and which a complete and interference free removal of the generated microfilm particles is assured. The exhaust shaft is connected near the output end of the milling cutter, and is also connected to a suction blower. An air stream passes through the air gap slot, which is formed between the milling cutter teeth and the tip of the cutter plate. A pressure air stream may be employed fed from the input side to the milling cutter or if a suction air stream is present, it functions at the output end of the milling cutter. It is preferred if the exhaust shaft is disposed in immediate proximity, that is, in the direction of the stream, behind the milling cutter, such that the sucked off particles pass with as favorable a flow pattern as possible in free fall into the exhaust shaft.
