A detecting mechanism in a film magazine spooling machine for detecting a missing or displaced film end portion of a film magazine. The detecting mechanism comprises a sensing mechanism movable to a position for sensing the edge of an accurately positioned web end portion. If such web end portion is missing or displaced, and hence not sensed, a signal generated by the sensing mechanism inhibits a machine function logic control circuit inhibiting machine functions, such as the operation of an end cap staking mechanism. The signal further actuates a diverting mechanism for diverting the defective magazine, and an annunciator to alert the operator. |
