Managing web tension across multiple winding stations requires a mechanism that offers dynamic adjustment and consistent control. The Differential Shaft by Cbbmachine provides this solution by allowing independent rotation between cores while maintaining balanced torque—an essential feature in slitting, rewinding, and laminating applications where product variation is inevitable.

This specialized shaft uses friction rings or ball mechanisms to permit controlled slip between cores on the same shaft. As a result, each roll can rotate at a slightly different speed, compensating for material thickness, diameter variance, or winding irregularities. This flexibility prevents wrinkles, tension spikes, and misalignment, which are common issues in high-speed converting lines.

Its construction is optimized for repeatable performance, with a core-locking structure that ensures secure grip without damaging the material. Operators can easily change or reposition cores during operation, making the shaft a practical choice for jobs involving frequent setup adjustments or variable batch sizes.

The design supports both paper and film processing, as well as more delicate substrates like non-wovens or foil. Whether you're working with lightweight materials or dense laminates, the shaft's self-compensating mechanism ensures even torque distribution across all cores, regardless of line speed.

For facilities using fully automatic systems, the differential shaft integrates smoothly into existing drive configurations. It requires minimal manual intervention and can often help reduce web breaks or downtime caused by uneven roll build-up. This improves overall output and reduces waste, especially in large-scale production environments.

With growing demand for flexible manufacturing, a tool that simplifies web control while improving quality is a valuable asset to any converting setup.
