Abstract

In a monitoring system ( 1 ) for an apparatus ( 2 ) for producing and/or processing a material web ( 4 ), the monitoring system has at least one processor ( 10 ) and is equipped to perform a state and process monitoring step at the apparatus by detecting and synchronously visualizing signals, which can be generated by at least one first analysis device ( 5 ) for detecting tearing of the material web ( 4 ) in the apparatus ( 2 ) and by a number of further analysis devices ( 6 a, 6 b, 6 c, 6 d ) for detecting physical measurement and influencing variables in the region of the apparatus.

First claim

What is claimed is:
