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.

Pneumo-Hydraulic Web Guides

What are Pneumo-Hydraulic Web Guides?

Many displacement guides, steering guides, unwind / rewind guides manufactured in the 1960’s, 1970's, 1980’s and 1990's were controlled using both pneumatic and hydraulic control systems which are often referred to as pneumo-hydraulic web guides. These web guide were really common before the mass adoption of the electronic (analog and digital) controllers and electric actuators. A lot of these units were predominant in blown film lines, extrusion lines, flexographic printing presses and even in paper converting machines.
