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

Guiding a web by the edge of labels that have color changes

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. 

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.
