Abstract (en)
[origin: US4355227A] Microfiches to be destroyed by heat treatment are placed within a disposable tube fitted with a sealing plug, then baked to a sufficient temperature to cause melting and discarded. The apparatus comprises an electric heating resistor and a tubular heating jacket for receiving the disposable tube, the sealing plug being forcibly engaged in the tube by means of a cap which is screwed down by hand. All negative sheets and documents having a photosensitive surface such as microfiches are destroyed economically without any contaminating waste products.
