A method for detecting faults in sheet material, particularly folds in steel sheet which is being rolled to final specifications, consists in coupling a sensor which is sensitive to vibration in the rolling apparatus and monitoring an oscillating electric signal generated from the sensor to detect spikes which correspond to faults in the sheet material. A system for implementing the method is also provided.

L'invention concerne un procédé permettant de détecter des défauts dans un matériau en feuille, en particulier des plis dans une feuille en acier enroulée selon des spécifications finales, qui consiste à coupler un détecteur sensible aux vibrations dans l'appareil de laminage et à surveiller un signal électrique d'oscillation émanant du détecteur qui repère des pointes qui correspondent à des défauts dans le matériau en feuille. L'invention concerne également un système permettant de mettre en oeuvre ledit procédé.
