Automatic Web Tension Controller for Precise Closed-Loop Web Tension Control

The XWDGM Automatic Web Tension Controller is a high-performance closed-loop tension controller designed to deliver accurate and stable web tension control throughout the entire production process. It is widely used in slitting, rewinding, printing, laminating, coating, paper converting, flexible packaging, textile, and lithium battery manufacturing industries.

By receiving real-time feedback from a Through-Shaft Tension Sensor and load cell system, the controller continuously monitors actual web tension and automatically adjusts connected magnetic powder brakes, magnetic powder clutches, pneumatic brakes, servo drives, or frequency-controlled motors. This ensures constant web tension regardless of roll diameter changes, machine speed fluctuations, or material characteristics.

Compared with conventional manual tension control systems, the XWDGM Automatic Web Tension Controller provides faster response, higher accuracy, and improved production efficiency while significantly reducing web breaks, wrinkles, telescoping rolls, stretching, and material waste.

Frequently Asked Questions

What is an Automatic Web Tension Controller?

An Automatic Web Tension Controller is a closed-loop control device that maintains constant web tension by processing signals from load cells or tension sensors and automatically adjusting brakes, clutches, or drive systems.

How does a Closed-Loop Tension Controller work?

The controller continuously compares actual tension feedback with the target tension value. It automatically adjusts output torque to maintain stable web tension throughout the production process.

What is the difference between open-loop and closed-loop tension control?

Open-loop systems estimate tension based on roll diameter calculations, while closed-loop tension controllers use actual feedback from tension sensors or load cells to achieve higher accuracy and stability.

Which machines use Automatic Web Tension Controllers?

Automatic Web Tension Controllers are widely used in slitting, rewinding, printing, laminating, coating, flexible packaging, paper converting, and lithium battery manufacturing equipment.

Can this controller work with magnetic powder brakes and clutches?

Yes. The XWDGM Automatic Web Tension Controller is designed to work seamlessly with magnetic powder brakes, magnetic powder clutches, pneumatic brakes, and other torque control devices to achieve precise web tension regulation.

Can the controller connect to load cells and tension sensors?

Yes. The controller supports load cell feedback and various tension sensor configurations, enabling highly accurate closed-loop tension control for demanding industrial applications.
