Cbbmachine’s Differential Air Shaft for Perfect Web Tension

In high-speed converting and slitting operations, the Differential Air Shaft from Cbbmachine offers a reliable solution to the ongoing challenge of maintaining consistent tension across multiple webs. This precisely engineered shaft ensures that each roll—regardless of its diameter or material thickness—receives the right amount of torque, resulting in smoother, more accurate rewinding processes with minimal manual intervention.

At the core of this shaft’s performance is its integrated air-pressure and friction-based mechanism, allowing independent torque control on each core. When air is applied, the internal mechanism activates friction elements that intelligently adjust the torque transferred to each roll. This eliminates issues like uneven winding, core slippage, or web misalignment that often occur in conventional setups.

The Differential Air Shaft is especially valuable for production environments handling mixed-width rolls or materials with varying elasticity. It compensates for subtle differences automatically, preventing common problems such as telescoping, scalloping, or web wrinkles. The outcome is increased product consistency, reduced material waste, and enhanced machine uptime.

Designed for durability and ease of use, the shaft’s lightweight aluminum body houses precisely machined internal components that resist wear over extended use. It allows for quick changeovers between jobs, thanks to user-friendly inflation valves and friction ring designs compatible with standard cores. This flexibility reduces downtime and supports leaner, more responsive production workflows.

Another advantage lies in its adaptability. Whether installed on new equipment or retrofitted to existing machinery, the shaft integrates seamlessly without requiring major modifications. Its dependable performance makes it ideal for flexible packaging, label stock, medical film, and other sensitive roll-to-roll materials that demand tension precision.

By delivering balanced torque to each roll and maintaining uniform winding density, this shaft plays a critical role in boosting output quality and operational consistency. It's not just an accessory—it's a productivity multiplier.
