Dover Flexo Electronics - Major Events since Start Up

  • 1974 -  DFE opened for business, in a garage in Somersworth, NH.         

  • 1976 -  Introduced the "RTC" and "UTC" lines of rewind and unwind tension controllers. These were relatively small modular devices having plug-in circuit cards. The only other manufacturer, at the time, offered their devices in quite large enclosures and did not offer them without enclosures. Ours were much easier to install and service.

  • 1978 -  Dover Flexo Electronics incorporates.

  • 1983 -  Kenneth Ekola bought his partner's DFE stock and became the sole owner.

  • 1983 -  Introduced the "P3" pneumatic tension controller. It was even smaller than the RTCUTC controllers and utilized an advanced servo valve which was also used in jet engines. It was available without an enclosure and with a remotely located operator panel, for the first time.

  • 1985 -  We moved to our present location which had 3 times the space of our old one. 

  • 1986 -  Designed and introduced our first tension transducer, the Model "U" (universal). Patented in 1987.

  • 1987 -  Invented and introduced the Model "TR" Tension Roll® transducer which combined a dead (non-rotating) shaft idler roll and tension sensors in one easily-installed package. Patented in 1988.

  • 1988 -  Designed and introduced the Model "DS" transducer, for dead shaft idler rolls.

  • 1989 -  Designed and introduced our own pneumatic, dual-disk tensioning brakes .

  • 1990 -  Introduced the Model "C" (convertible) tension transducer for both dead- and live-shaft idler rolls. It has become an industry standard. Patented in 1992.

  • 1994 -  Introduced the "SteadyWeb2" analog tension controller . The first device capable of use in all three tension zones: unwind, intermediate, and rewind. It was a big hit and we have sold thousands.

  • 1995 -  The "SteadyWeb Microprocessor" controller was introduced. It was our first digital controller. It featured a knob for scrolling up and down instead of buttons. Customers liked that.

  • 1996 -  We doubled the size of our building and built a test facility for product development and training.

  • 1998 -  The "WebHandler2" small analog tension controller was introduced for use in all tension zones.

  • 2003 -  Introduced the "WebHandler3" , an advanced small digital controller.

  • 2007 -  Invented and introduced "Quik-Cal " on our Ti17C TrueTension amplifier. This is a time-saving and labor-saving pushbutton tuning feature. It is now used on all new DFE amplifiers, indicators and controllers.

  • 2011 -  Introduced the "SteadyWeb5 " digital tension controllere for use in all tension zones. A graphic display, instead of a a simple tension meter, makes it very easy to use and program. A knob is used for menu-item scrolling, instead of buttons.

  • 2011 -  Invented and introduced the "Silencer Pad " for our pneumatic brakes. It easily eliminates the squeal common to all pneumatic dual-disk tension brakes. Patent pending.

  • 2013 -  Introduced the "EasyWeb Torque Controller ". A lower-cost open-loop diameter calculator controller for tension control in less demanding applications.

  • 2014 - The intrinsically-safe tension amplifier FireGuard2™ receives UL certification and is released to the market. The FireGuard2 limits the energy to tension transducers in a manufacturing area with flammable vapor present to reduce fire or explosion risk.

  • 2014 -  DFE, the tension control specialists , celebrate 40 years of tension equipment service, manufacturing excellence and design innovation.

  • 2015 - DFE reaches a production and sales milestone by shipping the 10,000th Tension Roll Transducer to a North American manufacturer of printing presses. Over 86,000 DFE tension transducers have been sold over the past 40 years.

  • 2016 - DFE is issued U.S. patent for the Silencer™ no-squeal friction pad technology used with Dover's pneumatic disk brakes. The company has a 100% success rate in eliminating unwanted brake noise with Silencer™ pads installed. DFE guarantees that if a customer experiences a squeal problem on a DFE brake that the company can't resolve, a full refund of the brake cost will be issued.


    This list describes only a sampling of the multitude of product designs DFE has produced over the years. Many new concepts and products are currently in the works to assist our process manufacturing customers with their web tension issues.
