<%=company%> WebVision Digital Break Recording System provides the latest technology and tools to record, analyze and determine the cause of costly sheet breaks. Using CCD camera technology and high-speed digital signal processing, the system continuously monitors all of the critical locations on the paper machine, coater, winder, etc.
Over the last 3 years, Papertech has become the most experienced and widely used supplier of event capturing technology. Our advanced, fully digital technology leads the industry in offering papermakers the fastest and most complete way of solving the reasons causing breaks.

WebVision offers the following capabilities and features:

  • Components designed specifically for harsh paper machine operating conditions.
  • High-image resolution, exceeding 300,000 pixels per image.
  • Cameras record a minimum of 2 minutes (at 60 images/sec NTSC, 50 images/sec PAL) or 4 minutes (at 30 frames/sec) of history.
  • Industrial water and heat resistant compact camera enclosures, along with effective lens cleaning methods to allow monitoring of all required locations.
  • Intuitive Windows NT operator interface that includes a customized paper machine schematic for quick access of each camera location.
  • Large capacity break library for storing breaks over several weeks.
  • Camera-to-camera synchronization & grey scale image analysis for holes, edge faults, etc, complete with region-of-interest feature.
  • Multi-level, high resolution zoom.
  • Easily upgradable to include additional cameras.
  • A variety of unique techniques to assist in finding the reason for the break.
  • Ability to download & upload data from a millwide system.
  • Available in both NTSC and PAL standards.
  • Fully UL/CSA/CE compliant.

Results
To date, event monitoring systems have provided papermakers an exceptional tool to reduce breaks. With a sufficient number of cameras correctly placed, the ability to see breaks is 95% to 100%. Reduction in breaks from previously unknown causes has ranged from 20% to over 80%, resulting in payback periods of less than 3 months.
Conclusions
Minimizing all sources of paper machine breaks mean dramatic increases in operating efficiency and production. WebVision camera recording and software technology offers users effective and reliable event capturing to locate and solve the source of their breaks.

Using the latest camera technology and high-speed digital signal processing, the system continuously monitors all of the critical locations on the paper machine, coater, winder, etc. With the use of "instant replay", you can view the complete break event in slow motion. The system offers many powerful features such as camera-to-camera synchronization and gray scale image analysis that make it very fast and easy for the operator to find the source of the problem.
