In a machine for processing mail articles, the method of distinguishing between mail articles (P1, P2, P3) contained in envelopes made out of paper and mail articles contained in envelopes made out of plastics material, consists in displacing each mail article in front of a pressure member (5) so as to produce an acoustic signal that results from a suction effect of the pressure member on one face of said article while it moves in front of said pressure member, and in comparing said acoustic signal with a reference signal in order to detect whether the envelope of said article is made out of paper or out of plastics material.
Le procédé pour discriminer dans une machine de traitement d'articles de courrier, des articles de courrier (P1, P2, P3) mis sous enveloppe en papier et des articles de courrier mis sous enveloppe en matière plastique, consiste à déplacer chaque article de courrier devant un organe à dépression (6) afin de produire un signal acoustique résultant d'un effet de succion de l'organe à dépression sur une face dudit article alors qu'il est en mouvement devant ledit organe à dépression, et à comparer ledit signal acoustique avec un signal de référence pour détecter si l'enveloppe dudit article est en papier ou en matière plastique.
