<p>In the method for the destruction of plastic microfilms, the microfilms are subjected to a hot-air flow on a depository grating (4) and are melted, and the melted material drops through the depository grating (4) into a collecting vessel (5) and solidifies in this. A hot-air melting furnace (1) suitable for carrying out the method consists of a melting chamber (2) equipped with a depository grating (4), of a collecting vessel (5) arranged under the depository grating (4), of a hot-air generator (6) and of devices which convey the hot air through the melting chamber (2). <IMAGE></p> |
