Dover Flexo Electronics Announces Release of EasyWeb(TM) Torque Controller
Press release date: February 18, 2014
Rochester, NH – Dover Flexo Electronics, which manufactures, sells, and services a complete line of tension measurement, tension display, and tension control products for a wide variety of industries worldwide, announces the release of its EasyWeb™ Torque Controller.
The EasyWeb™ Torque Controller is a lower-cost solution for applications in which precise tension control is not essential. The EasyWeb™ is an open-loop torque controller that maintains constant web tension and provides taper tension to center-driven rewind or unwind applications. Web tension is regulated by controlling motor or brake torque based on varying levels of roll diameter. An inertia compensation parameter is provided to obtain greater control of web tension during changes in line speed.
The EasyWeb™ can accept signals from a direct diameter sensor or calculate diameter using line and roll speed signals. The user interface provides a bright OLED display for easy viewing in any light and from any angle, while a large front dial allows fast, easy scrolling through the user menu.
DFE offers both open-loop and closed-loop automatic tension controllers to meet the application needs and budgets of almost any printer, converter, or web processor. DFE's SteadyWeb5 Tension Controller is an example of a closed-loop tension controller that employs a feedback mechanism to directly measure web tension and transmit that value back to the tension controller.
But that level of precision is not necessary in all applications. When a slight amount of tension deviation can be tolerated, an open-loop controller like the EasyWeb™ Torque Controller—which achieves the same continuous tension adjustment on the web—provides a powerful yet economical solution for many customers.
