摘要： A driving belt (2) operatively mounted on at least a first (3a) and second (4) pulleys electrically insulated from each other, is provided with an electrically conductive covering fabric acting in contact relationship with the pulleys. By applying an electric voltage to the pulleys (3a, 4) the electric resistance value offered by the belt (2) is detected and this value is compared with a reference value to which a given degree of wear of the belt corresponds. When the detected resistance value is greater than the reference value, a danger signal is emitted. The danger signal is inhibited during the belt operation and during a predetermined waiting time starting from the moment of the belt stopping in order to avoid the resistance detection to be altered by electrostatic charges present on one of the pulleys (3a, 4) and/or the high temperature in the vicinity of the belt (2).
