TENSION CONTROL SYSTEM

Tension control system automatically controls tension during manufacturing and various treatment processes of paper, sheet steel,firm, foil, rubber, fabric, textile, ...

Tension Control Applications

  • Web-fed offset printing
  • Web- fed rotogravure press
  • Business form printing press 
  • Slitter
  • Coater
  • Laminator
  • Winder
  • Cutter
  • Calender
  • Corrugator

When a web of these materials is unwound or rewound the web tension varies as the roll diameter of the material of the material changes. Web tension must be maintained at a constant level to prevent wrinkles, sags, changes in width or thickness, or breakage of the web. In printing processes, variable tension causes a paper web to stretch or shrink, causing sudden register errors. This problem necessitates tension control.

 

Tension sensors are mounted at both ends of a sensor roll. The tension controller can be operated simply a stable proportional + integral action with a constant loop-gain circuit. This configuration provides both responsivity and stability regardless of roll diameter.

 

The actuators include both an electromagnetic brake and pneumatic brake for use when unwinding.  The electromagnetic brake can be connected directly from the controller but the pneumatic brake must be used with an electro-pneumatic converter. Winding can be achieved using many systems, including an electromagnetic or pneumatic clutch, and electromagnetic coupling motor or a torque motor.
