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
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

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.
