摘要： A method of operating a packaging line comprises the following steps:(a) sensing the absence and presence of an operationally sufficient quantity of wrapper sheet supply for a bag making station of the packaging line;(b) sensing the absence and presence of an operationally sufficient quantity of bulk material supply in a metering and filling station of the packaging line;(c) sensing the absence and presence of the bags on a first conveying lane of the packaging line;(d) sensing the quantity of the bags on a second, accumulating conveying lane which adjoins the first conveying lane and receives the filled and closed bags therefrom, to determine a receptiveness or non-receptiveness of the second conveying lane;(e) allowing a start-up of the packaging line only if the sensing steps (a) and (b) determine a presence of bags on the first conveying lane and the sensing step (d) determines a receptiveness of the second conveying lane; and(f) allowing the stoppage of the packaging line only if the sensing step (c) determines an absence of bags from the first conveying lane.
