In a corrugated board production line, a Tension Controller is mainly used to control the web tension of the base paper during unwinding, conveying, preheating, corrugating, and laminating processes. It is an important control component for ensuring stable paper web running and consistent finished-board quality.

Key Features

• Stable tension control: Continuously monitors web tension and automatically adjusts braking force or driving force to maintain the desired tension level.

• High-precision control: Minimizes tension fluctuations and helps prevent problems such as loose or excessive tension, web misalignment, wrinkles, and paper breaks.

• Automatic closed-loop control: Typically consists of tension sensors, a controller, and an actuator. The system uses feedback signals to automatically regulate tension.

• Fast response: Quickly adjusts the output when production speed, roll diameter, or paper load changes.

• Adaptable to different paper grades: Tension parameters can be adjusted according to different paper weights, paper grades, web widths, and production speeds.

• Reduced paper waste: Stable tension helps minimize web breaks, wrinkles, stretching, and deformation, thereby reducing raw material waste.

• Improved board quality: Consistent web tension contributes to better flatness, bonding quality, and dimensional stability of corrugated board.

• Easy integration with production lines: Can typically be integrated with PLCs, frequency converters, servo systems, tension sensors, and other automation equipment for centralized line control.
