The benefits of a high-quality tension control system include: © 2021 Montalvo Corporation. Overall, installing a web tension controller can decrease the variation of tension significantly. Maintaining proper tension gets increasingly difficult as roll diameters decrease and changes happen more frequently. When installed in place of a standard dead shaft idler roller, the MAGPOWR Tension Sensing Idler Rolls deliver precise web tension measurement. The core of T-one is the P.I.D. It can also output 0-10V voltage signal to control vfd, servo motor or other actuators to perform high-precision tension control on the coil material. Web tension control refers to the process of controlling tension while transporting a web. Web Tension Controllers by Double E. Double E offers a variety of web tension control systems available using load cells, dancers, ultrasonic sensors, and amplifiers. This means that as a roll diameter increases or decreases, torque must be adjusted to maintain tension at the optimal value, or setpoint. As a roll diameter increases or decreases, torque must be adjusted to maintain tension at the optimal value, or setpoint. Posted by Bryon Williams & filed under Article Library, Montalvo News, Web Tension Control Blog. The sensor provides a high precision signal with high speed and can be applied in conjunction with magnetic powder brakes, pneumatic brakes, electric motors, etc. Closed Loop Tension Control refers to a continuous flow of communication from a web tension measurement device, to a torque controller, to a torque device. Quality tension control helps to eliminate these scrap producers by creating a uniform and consistent process. In the sysem, dual tension signal was sent to the controller, the controller compares the target tension with the actual tension and calculates the output with a build-in PID algorithm, then output a compensating signal to a tensioning device such as a powder brake, clutch or a DC drive to get the accurate control of tension. Often we find that due to their manufacturing process or poor tension control, manufacturers are not able to run their material rolls all the way down to the core affecting both productivity and profitability. This more or less is leaving money on the core, only to end up as scrap. So in a basic sense, by controlling the torque in a uniform manner in relation to the roll, we control tension. This ensures that throughout your entire process your tension is consistent, uniform and precise. ), Automated, consistent and continuous production. Basics of Web Tension Control Summary Presenter: Darrell Whiteside, Sales Channel Manager – Tension Control Maxcess International This presentation is intended to take the mystery out of web tension control. This paper is a review of the fundamentals of web tension control, covering the following topics; Machine sections (unwinds, rewinds and driven m… Tension is the pull or strain put on a web of material that tends to stretch it in the machine direction. The LCD and indicators make the user can opearate the controller easily without long time learning. The web must be “in traction” with all machine idler rolls and driven rolls to ensure proper web handling and control. Tension control and regulation are necessary to keep constant the desired web tension, avoiding the possibility of material breaks in any phase of web … Load Cells measures Tension ! The production of high quality laminates requires a precise detection and control of the tension of a web.The more influent parameter is the tension of the material, for this reason it’s necessary to have a tension regulator that ensures a correct and constant value during the whole working process. Web Tension Controllers. Web@tens has been appropriately designed for the web tension control in closed-loop systems. Web Tension Controllers Web tension has an important role in the sectors of converting, paper and carton board, aluminium foil, textile, wire and cables. The measuring force is detected via a bi-directional strip to which the strain gauges are applied, as a result of which an analogue measured signal proportional to the web tension is output. Function. These controllers are made in accordance with the set industry norms using the sturdy raw material. In your current application could you double your speed without sacrificing end product quality? As the roll diameter builds, with a fixed torque, tension will decrease as the roll diameter increases. Web tension controller DC 62; Product description For use in the paper, film and textile industry ; Simple and fast commissioning of the web tension control ; Variable control structure for different application scenarios: "open loop" and "closed loop" Technical Specifications Web tension controller for sale, LCD display, high precision, multi-function, full digital intelligent automatic tension control, send 0-24VDC control voltage command for magnetic powder clutch/brake. ABB’s web tension system is the perfect choice for measuring web tension in paper mills or converting applications such as printing, laminating, coating, slipping, sheeting etc. An optimized web tension control system will ensure that the correct tension is maintained for any type of material, at any section of the machine and regardless of speed or process conditions. We can help you with a web tension control system, tension indicators, tensions controllers, as well as rebuild or repair your older Comptrol web tension control products. Buying Web Tension Controllers. We can replace other transducers / load cells on machines as well, try our web tension control system configurator, to choose a load cell that will work best for you. Web Tension Control The BXCTRL Web Tension Control is a solid state electronic control that receives a signal from dancer input sensors or two load cells (customer supplied).
