Tail threading ropes are used in a board machine when the sheet is fed through the machine after a standstill or a web brake. AI-technology has been adopted to avoid unplanned shutdowns caused by breaking of the tail threading ropes. Twelve cameras are connected to the AI-based machine vision system, which constantly monitors tail threading ropes. The AI-based machine vision analyses video material and when the risk of tail threading rope breaking is high operators are alerted. This enables operators to do a controlled replacement of the tail threading rope and avoid unplanned machine downtime.
