ABSTRACT:
The method of detecting plastics material, in particular for a postal sorting installation through which articles pass, is intended to distinguish automatically between articles having an outside surface made of plastics material and articles having an outside surface made of paper. The method consists in moving each article past an electrostatic generator, and then past a member for evaluating electrostatic charge so as to compare the charge on the article with a reference value in order to detect whether the article is a plastics article or a paper article. The method increases the reliability of detection.
