Original Press Release:
No More Erratic Dancing
(Vadnais Heights, Minn. - November 20, 2003) Nexen Group, Inc., today announced their new RSD250 Dancer Unwind Package. This package contains a totally pre-configured system that is simple to install, requires minimal calibration and keeps your web tension rock steady. The components include the controller (RSD250), pressure converter (EN50), air filter, dancer position sensor (DPS60) and all the cables and air line tubing.
The RSD250 uses air pressure to either increase or decrease the pneumatic brake torque, allowing the dancer roller to remain at it's mid-travel position in order to provide consistent tension during the unwinding process of paper, film, foil, or fabric. If the dancer arm position changes, Nexen's position sensor senses the movement and sends a signal to the RSD250, which provides a corrective signal to the tension brake to adjust and maintain the proper web tension. The RSD250 controller is housed inside an enclosure that requires either 120 or 240 VAC service. All DPS60, EN50, and external signals connections are made to the RSD250 via pre-wired connectors. All the pneumatic connections are made using tool-less quick connect fittings; making connecting components together fast and easy.
The only calibration the user needs to adjust is minimum and maximum travel position of the dancer roll. Based on machine type, the user can set the RSD250 for either momentary or maintained start/stop signal, adapting to any tension situation. The RSD250 package includes all the necessary components except the brake. The RSD250 Dancer Unwind Package is ideal for unwind stands with pneumatic brakes used to control the tension of paper, plastic, textile, or non-woven materials.
