Abstract (en)
[origin: EP0829352A2] A performance monitor/diagnostic system for a four colour rotary printing press enables the presence of damage or wear to the various rotating components to be detected. Each printing unit (2) has a bridge assembly of paired rolls symmetric to the track (1) comprising the rubber cylinders (4), plate cylinders (6) and the respective colour and humidity mechanisms (7,8). The cylinders (4,6) are mechanically coupled and their dynamic relationships are monitored via optically marked discs on the cylinders (4) scanned by the opto-electronic transducers (18,19,21,22) for evaluation (2) and comparison (34) with stored norms comprising previously established characteristic frequency spectrum.
