Abstract

L'invention est relative à un procédé et à un dispositif pour déceler des défauts dans l'enveloppe d'articles à fumer. Selon l'invention chaque article à vérifier est soumis isolément à un premier contrôle par la formation d'un premier gradient de pression et la formation d'un premier signal de contrôle, tandis qu'une valeur-limite supérieure est arrêtee pour la perméabilité à l'air de l'enveloppe, et qu'un article soumis au contrôle est jugé conforme, si le signal de contrôle se situe en-dessous de la valeur-limite superieure, les articles étant soumis à un second contrôle dont la sensibilité est la plus grande dans le secteur de la zone de perméabilité à l'air désirée, par la formation d'un second gradient de pression et la formation d'un second signal de controle, tandis que des variations du second signal de contrôle sont captées. Le procédé et le dispositif sont utilisables pour contrôler la qualité de cigarettes, cigares, cigarillos et analogues.The invention relates to a method and a device for detecting defects in the casing of smoking articles. According to the invention each article to be checked is subjected in isolation to a first control by the formation of a first pressure gradient and the formation of a first control signal, while an upper limit value is stopped for the permeability to the air of the envelope, and that an article subjected to the control is considered to conform, if the control signal is below the upper limit value, the articles being subjected to a second control whose sensitivity is the larger in the area of the desired air permeability zone, by the formation of a second pressure gradient and the formation of a second control signal, while variations of the second control signal are sensed. The method and device are useful for controlling the quality of cigarettes, cigars, cigarillos and the like.
