In this video, we explore the two main reasons for using center guiding in web handling systems, focusing on the advantages it brings when dealing with varying web widths and poor edge quality. The SCU6x Controller's advanced sensor technology allows seamless adjustments without the need to move sensors, accommodating significant width changes efficiently. This ensures high response times and minimizes wear on actuators. Additionally, for materials with irregular edges, center guiding helps average the measurements from both sides, leading to smoother edge profiles and improved roll quality. Learn how the SCU6x Controller can enhance your web handling process.
