  • System for detecting jams and other malfunctions in container processing equipment
    Patent number: 4720797
    Abstract: A control system is provided for a processing container line to detect the occurence of a jam or other malfunction within the line. The system compensates for the initialization of the line when a number of containers enter the line before any are discharged therefrom. The system also allows for a tolerable limit on the number of containers which may become "lost" in the processing line without indicating a jam in the line.
