| Abstract: |
A system and method for generating a time-to-break prediction for a paper web in a paper machine. This invention uses principal components analysis, neuro-fuzzy systems and trending analysis to form a model for predicting the time-to-break of the paper web from sensor measurements of paper machine process variables. The model is used to isolate the root cause of the predicted web break.

What is claimed is:
1. A system for predicting a paper web break in a paper machine, comprising:
- a plurality of sensors for obtaining a plurality of measurements from the paper machine, each of the plurality of measurements relating to a predetermined paper machine variable;
- a processor for processing each of the plurality of measurements into modified break sensitivity data; and
- a break predictor responsive to the processor for predicting a time-to-break of the paper web from the plurality of processed measurements.
