<p>The present invention provides a method for detecting defects in conveyor belt splices having magnetically permeable metal cords embedded therein as the conveyor belt advances through a conveyor system, said conveyor belt having at least one splice, wherein a first set of magnetically permeable metal cords coming from a first side of the splice extend into a second side of the splice and have ends which are embedded in the second side of the splice, wherein a second set of magnetically permeable metal cords coming from the second side of the splice extend into the first side of the splice and have ends which are embedded in the first side of the splice, said method comprising magnetizing the first set of magnetically permeable metal cords and the second set of magnetically permeable metal cords, and monitoring the magnetic image generated by a first pole at the ends of the first set of magnetically permeable metal cords and a second pole at the ends of the second set of magnetically permeable metal cords with a magnetic sensor to detect magnetic anomalies generated by cord defects, with the proviso that if the first pole is a positive pole that the second pole is a negative pole, and with the proviso that if the first pole is a negative pole that the second pole is a positive pole.</p> |
