Sometimes, when running web wider than a few feet, you can spot some unexpected bagginess, wrinkles or curl on one edge of the web that doesn't exist on the other. For diagnosing tension differential between both edges of your running web, or just to verify the tension is even from edge to edge, new TriViewTM LRT (Left-Right-Total) Tension Indicatoris the right device for the job.
TriView's user-friendly touch screen displays total tension, and shows the web's left- and right-side measured tension values, OR it shows a balance indication with any deviation between the left and right edges measured by an installed tension-sensing roll. Access to features and swapping view modes is a simple screen tap.
An idler roll with integrated tension transducers built into each end, the Tension Roll transducer is famous for being extremely rugged and long-lasting. It is the most reliable device of its kind in the converting and printing industries, while also being available on short lead times. Because Dover Flexo Electronics uses state-of-the-art roll production equipment, and has also recently increased its capabilities to machine raw stock, the company can meet demanding specifications and delivery requirements.
Need your tension rolls to be longer or to have a specialty finish or covering, or be able to operate at high speed? We welcome the opportunity to meet your strictest requirements.
Are you running idler rolls in pillow-block bearings on your machinery? The F transducer is a heavy-duty flat-style transducer that accurately measures web tension in machines using live-shaft idler rolls. One F transducer mounts under the pillow block bearing at each end of the roll shaft. Designed for use in demanding tension measurement environments—like paper processing—these transducers are built to last. The F transducer is housed in a rugged, corrosion-resistant base with a tethered stainless-steel top plate.
The heavy-duty F-type Tension Transducer replaces DFE's earlier model UPB transducers.
Pneumatic brakes can sometimes generate unpleasant noise for machine operators due to a variety of factors including vibration and friction pad wear. Brake manufacturers like DFE have spent years researching methods to counter squealing brake issues for customers. Three years ago our engineering team developed a squeal-killing cure with the design of a special friction pad that we call the Silencer™.
The FireGuard2 indicator measures process tension while providing peace of mind to converters, printers, coaters and laminators whose machines and operators may be exposed to flammable solvent vapor.The FireGuard2 shares the same footprint as original FireGuard Indicator, but runs on 24 VDC power.
Customers can usually save about 50% of the cost of a new Tension Roll Transducer by sending in an existing Tension Roll Transducer for refurbishing service (includes refinishing). Is it worth it? Check out a couple recent DFE Tension Roll transducer repairs with refinishing here .
The EasyWeb Torque Controller keeps tension stable, and within a desired tension range by tapering the torque down or up on a center-driven unwind or rewind based on an input signal from line-speed and roll-speed tachs, or from an ultrasonic sensor or rider roll.
The EasyWeb calculates the change in roll diameter throughout your winding or unwinding process and adjusts the torque output to your drive, clutch or brake to effectively taper web tension and keep your web from breaking, stretching, wrinkling, or curling. It allows the machine operator to focus on other aspects of your process than having to manually adjust the web tension for a quality outcome.
The SteadyWeb5 digital tension controller maintains set tension on a web in any zone to improve process consistency. The controller's new web-server option allows Ethernet communication for setup and control via connected PC or remotely from a wi-fi-enabled smart device.
For setup and configuration, SteadyWebTM5 users have a choice of the onboard graphic interface with a color backlit LCD and convenient scroll knob, or a communications option.
With closed-loop digital PID control the SteadyWebTM5 maintains set tension on the web to improve process consistency. The large, bright LCD display with color graphics simplifies setup and configuration, so that production engineers and maintenance techs can get machine operators trained in less time. The large front-panel knob allows quick and easy navigation and tension adjustment.
Like DFE's Ti11 Dual Indicator, the new TwinAmpTM Tension Amplifier is a versatile, rack-mount tension transducer interface for monitoring web tension in any two sensing zones simultaneously. Two Independent circuits on one card give the user cabinet space savings and lower cost than two separate amplifier cards.
TrueViewTM is a compact, low-cost general-purpose web tension amplifier and display for printers, converters and web process manufacturers.
The TrueView indicator amplifies a web tension signal from tension transducers in a process web path and displays the true tension reading on an analog or digital meter in the users preferred units....[more]
DFE has released a new line of narrow web tension transducers that can measure light to heavy running tension on web widths from six inches to twenty inches on printing presses and converting machinery.
