  • Patent number: 5085377
    Abstract: Process for feeding paper rolls for supplying web-fed rotary presses with paper rolls and for disposing of remnants from web-fed rotary presses, comprising a control system, which stores data on the location and the type of all paper rolls and disposal containers at any point in time. The system is designed to be so redundant such that partially manual or completely manual operation is possible in the case of failure of one or several components, as a result of which printing of the jeopardized publication is possible even in case of emergency, and the safety and ergonomic aspects are also not neglected even in an emergency situation.
