Web Guiding Monitoring - Roll-2-Roll Technologies LLC at Converters Expo 2022

Yes, we skipped exhibiting at Converters Expo last year, but we are back. After the hiatus in trade show attendance, it’s good to see Converters face to face. Better yet, we enjoy helping Converters solve problems that might seem unsolvable. 

This year we are sending two of our experts to work with you in solving your problem in web guiding and monitoring. Whether it’s an issue with edge, center or line guiding in a specialty area, or a difficult monitoring application, we have developed the technology to solve many problems in the industry.

Web Guiding Applications and Advanced Web Guiding Concepts - Single Edge Guiding

In 2020 we hosted a webinar on web guiding applications and advanced web guiding concepts as a continuation of the educational series web guiding fundamentals. This webinar was the follow up on our seminar on Web Guiding Fundamentals, presented earlier that year, and commented in a series of blog posts in 2021. We would like to share some comments on the points presented in this webinar in the form of a series of blogs.

Contrast Guiding Application - Using a Continuous Edge Contrast to Guide or Monitor a Web.

Another Option in Contrast Guiding when there is no Feature that could Mimic a Line.

In a previous post on contrast guiding we discussed using the negative space between straight edged labels as an intermittent linethat can be tracked by our sensor/camera and control system for web guiding applications. However, our system allows for other ways of using a contrast application that do not require a negative space that has characteristics of a line for the purpose of tracking.

Contrast Sensing Application - Guiding on Negative Spaces

Contrast sensing allows for a variety of applications to guide or monitor your web. These applications help you eliminate the need for a printed line. Eliminating the printed line saves the cost of ink to print the line and the web material where the line would be printed. 

A contrast is any visible printed, embossed or laminated feature on a web. Most of the time, a visible feature is understood to be visible with the naked eye. However, it can include UV printed features that are not visible to the naked eye, but are detectable for a UV type of sensor or camera.

CASE STUDY: Web Guide Upgrade Kit for Aging Web Guides

A major printer in the New England region had several web guiding systems with failing controllers, sensors and actuators. We were approached by their engineering department and we offered them the option of using upgrade kits with drop in actuators. This would allow them to keep the web guide mechanism and they would upgrade their sensor, controller and actuator to the latest technology in the industry.
