What Dover Flexo Electronics does

Dover Flexo Electronics (DFE) designs, manufactures, and sells tension measurement and control systems for continuous web, ribbon, and filament processing machinery. The company was founded in 1974 in a garage in Somersworth, New Hampshire, incorporated in 1978, and relocated to its present 300%-expanded Rochester, NH facility in 1985. It is a private, family-held company that has been independently owned for its full 50-year history, most recently transitioning ownership in 2020 from founder Kenneth Ekola to long-tenured employee Glenn St. Peter and his wife Cindy St. Peter. DFE employs 11–50 people and operates from a single US headquarters.

DFE's product portfolio is an integrated stack of complementary components: tension load cells and transducers (the patented Tension Roll®, Segmented Tension Roll®, Model C, Model F, Narrow Web, Very Narrow Web, and TriWheel™ filament and ribbon families); signal conditioners and amplifiers (TA1, TA500-EIP with EtherNet/IP, TA500-ECAT with EtherCAT, and the TI22 iAMP2); tension indicators with color touchscreen displays (TrueView™ 1100 and TriView™ TI31); closed-loop and open-loop tension controllers (SteadyWeb™ 6 digital and EasyWeb™ torque); and mechanical actuation via five sizes of dual disc pneumatic brakes, magnetic particle brakes and clutches, and hysteresis brakes. The architecture is protected by five US patents, including the original Tension Roll® integrated load cell/idler roll design and the Silencer™ brake pad system. Target end markets are OEMs, operators, and controls engineers in printing, coating, laminating, extruding, slitting, rewinding, battery manufacturing, wire and cable, fiber optic cable, nonwovens, flexible packaging, flexible displays, and composite materials production.

DFE generates revenue primarily through one-time hardware sales — load cells, amplifiers, indicators, controllers, and brakes/clutches — sold direct and through a network of regional manufacturer representatives at quote-based pricing, backed by an industry-leading 5-year warranty. A secondary aftermarket services stream covers equipment repair, refurbishment, and replacement, with a $150 evaluation fee for out-of-warranty products. The company has reported cumulative shipments of more than 86,000 tension load cells and claims the #1 position in tension roll transducers. There is no external investment, no public listing, and no disclosed revenue figure.

Its offering covers the full signal chain — tension load cells/transducers, signal conditioners and amplifiers, tension indicators/displays, and closed-loop tension controllers — paired with mechanical actuation including pneumatic disc brakes, magnetic particle and hysteresis brakes and clutches, and aluminum idler rollers. Products are sold direct and through manufacturer representatives to OEMs, machine builders, and end-user operators in printing, coating, laminating, slitting, rewinding, battery manufacturing, wire and cable, and flexible packaging.

Product overview

Dover Flexo Electronics (DFE) is a manufacturer of precision tension measurement and control systems for web processing and finishing applications. The product portfolio is organized as an integrated system of complementary components: tension load cells (including patented Tension Roll®, Segmented Tension Roll®, Model C, Model F, Tri-Wheel™, and narrow/very narrow web transducers) that measure web tension; signal conditioners and amplifiers (TA1, TA500-EIP with EtherNet/IP, TA500-ECAT with EtherCAT) that process and transmit measurement data; tension indicators (TrueView™ 1100, TriView™ TI31) that display tension values; and tension controllers (SteadyWeb™ 6 digital controller, EasyWeb™ torque controller) that automatically regulate tension. Mechanical actuation is provided through pneumatic disc brakes (60, 90, 110, 130, and 1800 series), magnetic particle brakes/clutches, and hysteresis brakes. All products are backed by an industry-leading 5-year warranty and manufactured in the USA.
