AT, Auto Tension Control, Web Tension, Powder Brake: Output Current: 5 Amps: Keeping the track of latest happening in this domain, we are engaged in manufacturing and supplying the premium quality of Torque Web Tension Controller.

The offered web tension controller is used for manual controlling of torque and tension. The Mechanical of Tension Control. Web tension and control sensors are the input devices used with tension control systems and web guide systems. Nexen’s web tension sensors include load cells for measuring the force applied to a sensor roller, roll diameter sensors, and rotary sensors used with dancer systems.

Nexen’s web guide sensors include both edge and line following sensors. The significance of web tension control Web tension effect achieved when opposing longitudinal forces are exerted on any substrate (e.g. paper, film, board, cable etc.). Experts in the converting and printing processes know how critical good tension control is to their process and that tension can represent a.

Web Tension Control Basics. Posted by Bryon Williams & filed under Article Library, Montalvo News, Web Tension Control Blog. What is Tension. Tension is the pull or strain put on a web of material that tends to stretch it in the machine direction.

It can be measured in pounds, ounces, grams, kilograms or newtons across the width of the web. THE MECHANICS OF TENSION CONTROL By Jeff Damour CONVERTER ACCESSORY COPORATION Wind Gap, PA USA Introduction This presentation is a basic tutorial in the mechanics of web tension control.

We will discuss: 1) What is tension. 2) Why is tension important to me. 3) Where is tension control important in the process. 4) How do tension controls work. Fitting the HTU module under the bearing to control web tension of paper during production: The HTU measures force in both vertical and horizontal directions.

This makes it possible to calculate the exact web tension and resulting force, even in the presence of alternating web angles. The low height of the HTU module makes it easy to fit into.

Tools. Montalvo has created a variety of tools to assist you in your web tension control calculations. Easy to use reference guides, formulas, and calculators help you keep your machines running at maximum productivity while utilizing only the proper equipment based on the needs of.

Actual tension and set tension is displayed on the digital meter. Standard features include auto/ manual, tension on/off, manual setting pot, soft start and mains on/ tension Controller ATC series is an enclosure which contains the outputs to control motor drive, powder brakes, pneumatic brakes etc.

Tension and roller weight Web tension and the mass of the roller are entered in Newton. If the roller weight is present in SI units (e.g. kg) please be sure to recalculate the mass to Newton before using the value in this software.

Then web tension to be entered is the total maximum tension. If the ten. Reference Book “The Mechanics Of Proper Web Tension Control Highly Extensible Webs cut at an angle so that the web tension deflects the lands outwards, carrying the web with them to provide the spreading action.

The amount of spreading is a function of. The goal is to provide ongoing constant tension control. Servo motors with closed loop control provide a solution for continuously making adjustments in these situations.

After constant tension unwinding, servo motors can really shine by dialing the web strains up or down, finding adjustments to make a strain-matched, no curl laminate. With open-loop web tension control, a device is installed to measure tension (e.g.

tension transducer). The measurement is available for reading on a meter or some type of display. Using this measurement, the operator of the machine may adjust the device manually to match the tension to the desired value as closely as possible. Tension Control - Foundations of Web Handling; Drives - Strategies for Global Tension Control; Nip Mechanics - Nip Load Quality Control; He has authored eight books and more than papers and articles such as his monthly Web Works column in Converting magazine.

His background includes a variety of web manufacturing and converting experiences.

roller via speed control faster or slower than the web. We would control the tension by controlling the amount of elongation in the material. The formula opposite describes this relationship.

V2 is our controlling function. Suppose we want to increase the speed of the material from m/min to m/min and EA is N.

For simplicity let T1 =0. The tension sensor is 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. Area of use. Block load cells are used for web tension control in practically all production plants where web-type materials are processed or.

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). It integrates two separate Digital PID Controllers and two separate Open Loop controls.

nAll set-up is done via SD card or computer. web tension control application for plastic, paper & packaging industries sun instrumentation and control offers a broad line of industrial control and automation solutions such as engineered systems, motion controllers, tension controllers, web tension control, tension transducers and load cells.
