Today, the manufacturers and users of machines for processing web-type materials are confronted with ever increasing demands: production processes should be even faster, while at the same time performed with greater precision, the quality of the finished product further improved while personnel, waste and, above all, downtimes, should be reduced to a minimum. A decisive contribution to the fulfillment of these prerequisites is made by web tension control systems by Erhardt+Leimer.

Controlled web tension is essential
Typically, web-type materials are fed from a roll to the machine, finished and then rewound. At each stage, web tension errors may occur that may lead to malfunctions and quality impairments. The elimination of these sources of error and ensuring a constant web tension during the production process is the task of E+L web tension control systems. Depending on the material type, application and task, Erhardt+Leimer offers a variety of systems with the latest technology: For decisively more quality and productivity that pays off.
Web tension after the unwinder
- Insufficient web tension causes slack in front of the transport drive
- If the web tension is too high, longitudinal creasing and textile web deformation may be caused
Web tension on the rewinder
- If web tension on rewinding is insufficient, roll telescoping may occur
- Excessively high tensile forces damage the inner windings
The solution: a continuous control loop
Any automation of a controller is based on the principle of a simple control loop. Even the most complex of tasks may be reduced to this control loop.
"As the market leader in automation and quality management, we know that precise web tension in the production process is the key to your product quality. Accuracy, reliable measuring equipment and state-of-the-art technology are the guarantees of success that all Erhardt+Leimer customers can count on."
