Tension Control Unit

Tension Control SystemTension Control SystemIn 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. 

Tension Control SystemJust 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.


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

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

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

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

v Indication and correction will be reliable, and efficient.

v 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. Manufacturer of Tension Transducer, Magnetic Particle Brake. Hence automated Web tension controlling is essential if objectives in this well known are to be pleased CPT series controls Unwind, Rewind and intermediate web tension.  

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

v Load cell feed back

v Diameter computation feed back

v D.C. regenerative brake

v A.C. motor based

Application Information: 

Tension Control System For Unwinder Unit And Rewinder Unit Of Converting Machines Constant Tension During Converting Process Is One Of The Main Criteria In Ensuring Good Quality End Product. Tension Of Web Is Decided By The Braking/Driving Torque Applied To The Roll Shaft And The Roll Radius. 

Tension = Torque / Radius. 

As The Roll Diameter Starts Reducing From Full Diameter, Or Increases From Core Diameter, The Torque Should Be Adjusted From Time To Time In Order Maintain Constant Tension. With Conventional Brake System, The Machine Operator Adjust The Brake In Steps Due To Which Tension Will Not Remain Constant During The Process.  

Our System Help Convertors Achieve Higher Productivity, Lesser Wastes And Increased Profits By Maintaining Constant Tension During Running Process. 

The Following Are Major Components Wit Tension Controller System:

v Tension Controller

v Tension Transducer

v Magnetic Particle Brake/Clutch/Motor/Pneumatic Brake 

Some Of The Major Benefits Achieved When Using Tension Controller Are:

v Set Value Of Tension Is Maintained Constant During The Process.

v Wastages Are Reduced Since The Roll Can Be Used Until Last Few Layers.

v Line Speed Can Be Increased.

v Operator Can Focus On Other Critical Parameters Of The Process During Machine Running Condition.

v Constant Tension Helps In Reducing Major Shift In Registration While Printing Which Normally Occurs When Frequent Adjustments Are Done With Manual Systems.

v Payback Period Is Usually Between 6 Months To 2 Years Depending On Type Of Material

Automate Web Tension Controller Operating Principle:

Material Tensions Set By Set Tension Potentiometer, The Set Value Is Compared With Actual Tension Value (Signal Come From Tension Transducer), The Compared Signal Will Give Error Signal, This Signal Is Amplified And Given To Brake /Motor. Special Electronic Circuit Will Compare With Actual Tension Value And Maintain The Same By Adjusting The Braking Torque Or And Speed Of Motor.
