Tension Control Systems
Web control systems include tension control and web guide systems for the web industry.
Tension Control Clutches
Rewind operations require smooth, consistent torque to wind roll of all types of materials. Continuous slip applications also need clutches to efficiently dissipate heat. Nexen tension control clutches, with closely held flatness and finish tolerances, combined with specific friction materials provide ultimate web tension control.
Tension Control Brakes
Unwind applications need brakes with consistent torque and good heat dissipation. Nexen tension control brakes have finned and/or drilled rotors engineered to remove heat effectively. Four unique designs and fourteen model sizes provide excellent performance and long life. Each brake series has multiple friction facing choices to suit specific tension applications.
Sensors
Web tension and control sensors are the input devices used with tension control systems and web guide systems. Nexen’s web tension sensors include load cells for measuring the force applied to a sensor roller, roll diameter sensors, and rotary sensors used with dancer systems. Nexen’s web guide sensors include both edge and line following sensors.
Tension Controllers
Precise tension control is vital to any web or strip fed operation, the product must be fed under tension, processed under tension and wound up again under tension. Tension controllers are an integral part in maintaining this set tension. Nexen tension controllers range from simple systems with diameter feedback (open loop), to dancer control systems, and the highest precision systems using web tension sensor feedback (closed loop).
Tension Meters and Amplifiers
Often times, you need to only measure the tension in a web, not control it, or integrate low voltage tension sensors into a user-designed control system. Nexen’s tension meters and amplifiers precisely measure web tension, while the meters provide an additional function of a live tension readout.
Auxiliary Controls
Auxiliary web controls, such as web break and splice detection, help yield high quality products with less machine down time.
Web Guide Systems
Controlled lateral alignment of the web is essential for providing high quality product and reducing scrap and waste. Nexen offers small to large web guides with or without the AE120 controller, in self-contained or free-standing units.
