Abstract
A manufacturing system includes rollers having synchronization marks to indicate complete rotations. Synchronization mark readers read the synchronization marks of the plurality of rollers and output roll synchronization signals. An encoder outputs a position signal indicative of a down-web distance of the web. An inspection system inspects the web and outputs anomaly data identifying positions of anomalies on the web. A synchronization unit receives the position signal from the encoder and the plurality of roll synchronization signals from the synchronization mark readers and converts the occurrence of each of the roll synchronization signals into down-web positions within a coordinate system associated with web process line. An analysis computer processes the anomaly data and the synchronization signals to identify repeated anomalies and to determine which of the rollers caused the repeated anomalies.
