Many industrial processes involve handling material in web form, commonly requiring the material to be unwound and rewound on spools and bobbins.
Variable Speed drives are ideally suited to provide accurate and effective control of material tension and have become the standard solution for winder applications, providing:
The final tension control solution will depend upon the material to be processed, the speed and diameter range over which it is to be run. Simple low performance systems can be based upon straight forward open loop torque prediction, while more sensitive applications may require the tension loop to be closed by feedback from a load cell. Some materials are better handled by running the drive in speed control with a dancer roll measuring the tension and modulating the winder speed.
Control Techniques has solutions that caters for all these options and are easy to set up and integrate into your any machine. Interfacing can be analog or digital, making the solution equally suited to refurbishment projects or new systems employing HMI and different fieldbus technologies.
Winder application solutions are available for Control Techniques AC, DC and servo drives. For more information click on the Contact Us link and a Control Techniques representative will contact you.
This video demonstrates the precision with which our winder solution tracks spool diameter, motor shaft speed, and dancer tension control.
