At April's International Converting Exhibition in Orlando, Florida from the 25th - 27th, attendees will be able to get some hands-on interactive time with the new tension measurement and control solutions from Dover Flexo Electronics (DFE).
TriView™ LRT (Left-Right-Total) Tension Indicator
Dover Flexo Electronics is pleased to introduce the TriView™ LRT (Left-Right-Total) Tension Indicator in an interactive demonstration at booth 102. TriView incorporates a user-friendly touch screen that can display tension in one of two ways. Total tension is always displayed; the machine operator can select between viewing the roll's left end and right end measured tension values, OR a balance indication that shows any deviation between the left and right ends of the roll. OR you can switch between the two views.
This ability to view any tension variation across the length of a tension transducer roll makes it possible for machine operators to equalize the tension at both web edges by making appropriate manual or automatic machine adjustments. TriView is an especially useful diagnostic tool on wider web machines that may be experiencing uneven web tensions at the edges.
Obviously, your ability to maintain consistent tension in your converting, printing, or finishing process directly effects the output consistency of your products. Visitors can see the controller output effects of a web tension setpoint change on a live interactive demo machine. Through our new linear translation demo stage, you'll get a clear idea of how well the SteadyWebTM5 tension controller adjusts on the fly to perfectly maintain your set tension on a web like the one in your own production facility.
The SteadyWeb5 controller with Quik-Cal™ is configured in the demonstration to take a tension input signal from a Very Narrow Web (VNW) tension transducer mounted on the new demonstration machine. Controller output changes are then reflected in a moving carriage on a horizontal slide rule. Visitors will see the carriage position change which corresponds directly to the control's output changes when the tension setpoint is adjusted.
Working with a tight budget AND require tension control for consistent finish quality of your label press output? Try installing a new EasyWeb Torque Controller on your web press or machine.
The EasyWebTM keeps your 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.
This open-loop controller calculates the change in roll diameter throughout the 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.
The FireGuard2™ tension amplifier 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 FireGuard2is an Intrinsically Safe, UL listed electronic device for measuring process tension from a Class I Division I or 2* manufacturing area. FireGuard2connects to tension transducers and a tension display installed in the hazardous area. Bylimiting energy delivered into the area to below the level required for spark ignition, FireGuard2significantly reduces the risk of fire and explosion when used with Dover's tension transducers.
