Normal Entry Rule for Webs: Essential Principles Explained

Dive into the fundamental 'Normal Entry' rule for webs traveling over rollers in this episode of 'Web Guiding Fundamentals.' Understand how a web always aligns itself perpendicular to the axis of a roller's rotation, even in cases of misalignment. Learn about the beam-like behavior of the web, the dynamics of its movement, and the importance of these principles for successful web guiding applications.

Understanding the Key Components of a Basic Web Guide System

In this episode, we delve into the essential elements of a basic web guide system. We explore the four main components: the guide structure or mechanism, the actuator, the sensor, and the controller. Learn how each component plays a crucial role in ensuring precise web positioning, from making physical contact with the web to providing feedback and executing corrective actions in a closed-loop feedback control system.

This video delves into the necessity of web guiding, covering key reasons such as material imperfections, machine variations, tension control issues, and operator errors. It explains the significance of web guides at different machine locations, differentiating between intermediate and terminal guides, and uses lamination as an example to illustrate the need for precise web alignment. Join us as we explore why and where web guides are essential in the roll-to-roll process.

Understanding Terminal and Intermediate Web Guides

In this video, we delve into the basics of web guides used in roll-to-roll machines. We explore various terminologies and types of web guides, including terminal guides like unwind and rewinds, as well as intermediate guides such as offset pivot guides and steering guides. Key distinctions and common applications in different industries are highlighted, providing a comprehensive overview of these essential components in web handling.

AIMCAL R2R 2020 Conference: Advanced Web Guiding Applications and Concepts

The webinar will cover sensing and measurement technology that are used in Roll-2-Roll® Sensors.

The presentation will cover:

• the fundamental working principle of the patented fiber optic technology
• how it differs from the conventional sensors
• benefits of the fiber optic technology
• application of the fiber optic sensor technology for sensing and measurement applications such as edge detection, width measurement, registration mark detection, flag detection, void/hole detection, tear detection, etc.

Web Guiding Applications 

• Edge Guiding
  • Straight edge
  • Fuzzy edge
  • Jagged edge
  • Wrinkles
• Center Guiding
  • One sensor measuring two edges
  • Two sensors, one each for an edge
  • Moving sensor center guiding (mechanical sensor repositioning)
  • Electronic guide point adjustment
• Line guiding
  • Contrast/pattern guiding
  • Line/contrast/pattern guiding on unwinds and rewinds
• Mechanical chasing application
