Web Position Sensor

How Accurate can you Guide a Web?

In this webinar episode on web guiding fundamentals, we delve into the accuracy of web guides, discussing various factors that affect their performance. We explore how steady state and transient errors can influence guiding accuracy and highlight the importance of machine quality, material properties, and proper installation. Additionally, we cover the design requirements necessary for achieving optimal web guide performance, emphasizing the need to understand conditions like web speed, thickness, and tension.

Importance of Sensors in Web Guiding Systems

In this episode of our webinar series on web guiding fundamentals, we dive into the critical role of sensors in web guiding systems. Learn about various sensor terminologies such as range, resolution, accuracy, and linearity, and understand the importance of accurate measurement for effective control. We discuss different sensor technologies including infrared, optical, and ultrasonic, and explore the challenges they face including issues with temperature drift and material properties. Discover why precise sensing is essential for guiding performance in web handling applications.

Single Edge Web Guiding Essentials

This episode is part of the ‘Web Guiding Applications and Advanced Web Guiding Concepts’ series and focuses on advanced edge guiding techniques, specifically single edge web guiding. The video explains the use of web guides and edge sensors for feedback in guiding mechanisms. It covers the positioning of sensors, the importance of alignment, and the common practice of repositioning sensors during web width changes. The episode also addresses potential operator errors and their impact on web guiding performance during product changeovers.

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.
