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.

Why is WPS being replaced by ODC? And what does it mean to existing customers?

Couple of weeks ago we made an announcement about our new Roll-2-Roll® Sensor product line ODC. We also announced the transition plan for existing customers using WPS to eventually transition to ODC. This caused some confusion and in this blog  we will address this.

ODC Linear Camera product line - replacement of the WPS Sensor product line

ODC Linear Cameras are single dimension cameras for web edge and contrast detection. They will have the same compact enclosure design of the WPS Sensor product line allowing for placement in spaces that fork style sensors and other vision systems cannot be placed.

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. 

Vacuum web guiding

Converting applications will typically require some type of guiding. It can be in the form of terminal or intermediate web guides, each with the peculiar conditions required to provide an effective placement of the web guide. However, all these applications are used in environments subject to atmospheric conditions. One of the most challenging web guiding applications deals with vacuum web guiding.

Negative Space Web Guiding - Consistency of the negative space

In negative space web guiding dealing with the consistency of the negative space is the same as if we were dealing with the consistency of a printed line for line guiding. 

The line has to be of the same width and color in order for the sensor to track it. Any variation and the sensor will not recognize it. The same thing happens when using the negative space as guiding feature.
