What Is a Web Tension Controller?
A web tension controller is a crucial device utilized in web processing machinery like printing presses and papermaking machines to regulate the tension of the web material.
Its primary function is to prevent sagging or breakage of the web material and ensure stable production. Two main methods of operation are employed: closed-loop control and open-loop control. In closed-loop control, sensors detect the tension of the web material, whereas in open-loop control, motors or brakes are adjusted based on preset values.
Web tension controllers find applications across various industries including printing presses, papermaking machines, packaging machinery, textile machinery, and plastic film manufacturing. Key features include stable production, precise tension control, versatile functions such as setting value adjustment, alarm systems, and data recording, as well as labor-saving capabilities and preventive measures against operational issues.
