Unwind/Rewind Guide

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.

Join us in this informative episode of our 'Web Guiding Fundamentals' webinar as we delve into the intricacies of guides structures of terminal web guides, otherwise known as unwind and rewind web guides. Learn about the various components, including the role of actuators and sensors, the design considerations for mechanical rigidity, and the importance of actuator sizing. Gain insights into the differences between guiding and chasing the web, and understand the advantages and disadvantages of these systems.

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.
