Rotary Die Cutting Tension Control

Rotary die cutting is a versatile manufacturing process that is used in a variety of industries such as packaging, labels, automotive, medical, electronics, textiles and aerospace. Controlling tension is crucial to ensuring the best die cutting performance in web fed processes. Closed-loop tension control systems maintain constant tension on materials being fed into rotary die cutters. This ensures a smooth, even feed of material, reducing the risk of jams or wrap-ups that can lead to downtime and waste.

Precise tension control utilizing load cell feedback also enhances rotary die cutting accuracy, resulting in a finished product that is more consistent in terms of shape, size and quality. Improvements to quality such as reduced stretching and tearing during material processing also translates into less scrap and more efficient use of materials.

By ensuring a consistent, even feed of material, a closed-loop tension control system also helps to reduce wear and tear on machine components such as rolls, gears, bearings, motors, brakes and dies. These holistic benefits help to preserve registration and die synchronization, while increasing machine life and decreasing maintenance issues.
