Fully digital break event recording technology, using the latest CCD cameras, now offers papermakers a new means of solving the causes of breaks. These systems are now able to continuously monitor, in realtime, all of the critical locations from the wet end to the dry end of the paper machine and coater. When a break occurs it is automatically stored into a permanent hard drive memory making it possible to fully analyze the events leading up to and following the break. This allows the papermaker to take the necessary corrective steps to prevent the break from occurring again.

A further advancement is real-time analysis is the ability of the cameras to analyze the image in real-time for any changes, and alarm the operator when they occur.

By using the latest technological advancements in digital image processing, these systems are now able to offer very high image resolution and can analyze the image for holes, edge faults and other operating disturbances.

This technology has rapidly gained acceptance in the last two years, and based on the rapid payback, mills have been steadily increasing their investments. There are now estimated to be over 200 digital systems in operation on all types of paper machines and coaters.

This paper discusses the latest available techniques in paper machine event capturing technology, their applications and the results that have been achieved to date.
