In modern production plants, processes are to large extending automated with manual interventions being reduced as far as possible. Hence automatic web tension controlling is essential if expectations in this respected are to be satisfied 

CPT series controls Unwind, Rewind and intermediate web tension automatically.

Just set the desire tension and the controller maintain it by automatically compensating for various roll diameters, speed, web material etc. actual tension and set tension is displayed on digital meter. Standard features include auto / manual, tension on/off, manual setting pot, soft start and mains on/off. Available with enclosure .Outputs available to control motor drives, powder brakes, pneumatic brakes etc.

FEATURES

Ø       Modular Design, allows the controllers to be configured to exact application

Ø       All customers' adjustments are on board to simplify set-up.

Ø       Microprocessor based control, can be used in any tension zone (Unwinder, Re-winder & intermediate).

Ø       To enter data using keypad allows the user to scroll through the selections and values, making set-up easy.

Ø       Indication and correction will be reliable, and efficient.

Ø       Close loop control by measuring web tension by two load cells, insures that malfunction or wrong web tensions are corrected.

We are one of the leading manufacturing companies engaged in the sphere of tension control system that is mainly used for precise tension & torque control solution in web converting industries during any web process.  It is very essential to maintain uniform tension for better quality and higher production & less wastages. Our tension control system is very useful for any winding & unwinding application to maintain tension uniformly throughout the process. Our Tension Control System is easy to install and operate.  

We offer different types of system like magnetic powder brake with:

Ø       Load cell feed back

Ø       Diameter computation feed back

Ø       D.C. regenerative brake

Ø       A.C. motor based

An Automatic Tension Controller (ATC) is a device used to automatically regulate the tension of a web (such as paper, film, foil, textiles, or plastic) during processing in various manufacturing operations. It plays a crucial role in industries that handle continuous materials, ensuring that the web moves smoothly through machines without overstretching, breaking, or causing misalignment.

Tension control is vital for maintaining product quality, preventing defects, and ensuring efficient operation of machinery. An ATC continuously monitors and adjusts the tension applied to the web to maintain the desired setpoint, improving the accuracy and consistency of the production process.

1. Sensors:

   • The system uses tension sensors (typically load cells or torque sensors) to measure the tension of the web in real-time. These sensors detect the force being applied to the material as it moves through the system.

2. Controller:

   • The controller processes the data from the sensors and compares the measured tension to the pre-set target value. If the actual tension deviates from the target, the controller makes adjustments by sending signals to the control mechanisms (such as brakes, motors, or dancers).

3. Actuators:

   • Actuators (such as pneumatic or electric brakes, motors, or dancer rolls) adjust the tension based on commands from the controller. For example, if the tension is too high, the system may apply a brake to reduce speed; if the tension is too low, it may increase the speed of the web or apply more force to the rollers.

4. Feedback Loop:

   • The system operates in a continuous feedback loop. As the tension changes, the sensors detect the change and send updated data to the controller. The controller then adjusts the actuators to correct the tension until it stabilizes at the target value.
