In roll-to-roll processing systems, the Differential Air Shaft developed by Cbbmachine enables consistent tension distribution across multiple rolls, even when core diameters or material behavior varies during high-speed production.

This specialized shaft uses a combination of air pressure and friction control mechanisms to independently regulate torque for each core mounted on a shared axis. Unlike traditional shafts, which rotate uniformly, this design allows for controlled slippage between cores—crucial for preventing wrinkles, stretching, or misalignment during winding or unwinding operations.

The differential mechanism automatically adjusts to the changing conditions of each roll. This dynamic response is particularly valuable in slitting lines, laminating machines, or any process where multiple strips of material are wound simultaneously. It ensures that every roll, regardless of slight variations in thickness or length, maintains optimal tightness from start to finish.

The structure typically includes air bladders, slip rings, and adjustable friction elements. These parts work together to manage slip torque with precision, without the need for constant manual readjustments. Not only does this simplify the operator's job, but it also reduces machine stoppage, material waste, and the risk of roll deformation.

Versatility is another strength. Whether you're handling paper, plastic film, or foil, this shaft adapts to a wide range of materials and core sizes. The quick air-pressure control function allows for fast core loading and unloading, improving efficiency while reducing downtime. In high-output environments where speed and accuracy are equally important, this adaptability proves essential.

When every roll must meet strict quality standards without slowing production, smart tension control becomes non-negotiable.
