When managing web processing across multiple rolls, the Differential Air Shaft from Cbbmachine offers a practical response to challenges involving uneven core sizes, slippage, and tension consistency. Engineered to accommodate multiple reels on a single shaft, it allows independent torque adjustment without compromising on stability or structural simplicity.

At its core, the design combines pneumatic expansion with precision torque balancing. This enables each roll to operate semi-independently, accommodating tension shifts in real time. Whether dealing with films, foils, papers, or textiles, this approach minimizes material deformation and helps maintain alignment across all winding layers.

A defining feature of this system is its ability to operate under varying air pressures, creating adaptive holding forces on different cores. This flexibility ensures that reels with slight diameter differences still rotate uniformly without compromising edge alignment. The result is more predictable winding and smoother end-product quality.

This system also simplifies setup and maintenance. Unlike traditional fixed-core solutions, which often require manual tension adjustments or separate shafts, the differential air shaft streamlines configuration. Operators can quickly insert or remove cores, minimizing downtime during material changes and enabling more frequent format shifts without resetting the entire mechanism.

The shaft's design is compatible with both automatic and manual tension control systems. This duality makes it suitable for converting lines, lamination units, slitting machines, and other modular equipment where adaptability is valued. Its wear-resistant surface finish also enhances longevity, even under frequent inflation-deflation cycles or high-speed operation.

As the need for multi-format flexibility and precision continues to shape modern production environments, shaft systems that balance adaptability with control will gain increased relevance. This air-powered differential solution reflects that shift—efficient, responsive, and integrable.
