Published: April 16, 2009, By By Greg Cober, Warner Electric One of the challenges in working with tension control systems is working with closed loop dancers. While dancers are a seemingly simple mechanism, there are complexities below the surface that can impact system performance significantly.

Although closed loop tension control systems offer the most advantageous method of providing web tension control, be it dancer or load cell, there are some limitations to each type of system. In dancer systems, more space is required in the machine to accommodate the dancer arm and rollers, and some method, preferably an air cylinder

QB3 High Flow (30 SCFM) Electronic Pressure Controller. Select options. A single QB3 electronic pressure regulator can be used to control the tension of a dancer arm by controlling the pressure of a cylinder. A rotary angle position sensor then sends feedback to the controller. In this application, the position of movable roller ...

Dancer system Let's look at a typical dancer control system. Figure 1. In this system, the restraining torque is provided by a pneumatic brake, which is operated by a currenttopressure proportional valve, being controlled by the dancer tension controller. A magnetic particle brake could also be used, in which case, the I to P valve is not ...

Abstract The plant considered in this paper is an industrial winding system with pendulum dancer mechanism. Such dancer have been rarely presented and modelized in publications. Transport system dynamics change dramatically due to the wide variation in roll radii and inertia. Industrial systems typically use decentralized PID controllers.

Two different ways of regulating the paper web tension in an offmachine coater, by using either a tension controller with load cells, or a position controller using dancer rolls, are compared. The two systems are analyzed from the regulation point of view: system stability and response times. The stability and response analysis was performed on a computer model using data from an offline ...
