When converting and slitting operations demand precision and adaptability, the Differential Shaft from Cbbmachine delivers a high-performance solution engineered to optimize tension control across multiple rolls. This innovative shaft system is designed to resolve issues common in multi-reel rewinding—such as uneven tension, misalignment, or speed variation—by enabling independent rotation of each core while maintaining uniform torque.

Ideal for film, foil, paper, and nonwoven industries, the differential shaft uses friction-based tension adjustment to ensure balanced rewinding across all lanes. Its core-slipping mechanism automatically adjusts to discrepancies in roll diameter or material elasticity, reducing web breakage and material waste. The result is higher productivity and improved final product quality, especially in operations running at high speeds or with delicate substrates.

This shaft type stands out for its reliability and ease of integration. Its modular design allows for easy adaptation to various machine widths and core sizes, while its robust construction supports long-term, heavy-duty performance. The reduced need for manual tension correction lowers operator fatigue and error, making it an ideal choice for modern, automated production environments.

Another key advantage is the smooth and quiet operation, even under fluctuating loads. Its internal components are engineered for low-maintenance functionality, with easy access for cleaning or part replacement. By allowing each roll to rewind at its own pace while remaining synchronized, it eliminates the compromise between speed and consistency.
