rewind guide

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.

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.

Roll-2-Roll Technologies doesn't just cater to the narrow web guide applications. Our line of actuators can help you in both narrow and wide web applications at any point in your converting process that requires accurate and precise positioning of your web.

Electromechanical actuators are used when quick reactions to changes in the web position are needed. The actuator connects directly to the control unit.

Do you have an existing unwind or rewind guide with outdated sensors and control unit? We now have a solution with our rewind/unwind replacement kits featuring ARIS web positioning sensors and control units for all electromechanical, pneumohydraulic rewind/unwind systems, providing advanced edge and center guiding.
