What is a Differential Shaft?

A Differential Shaft is a precision winding shaft that allows multiple slit rolls to maintain independent winding tension during the rewinding process.

Unlike conventional winding shafts, a Differential Shaft automatically compensates for material thickness variations and roll diameter differences by allowing controlled slip between individual cores and the shaft body.

This technology helps:

• Improve winding quality
• Reduce telescoping rolls
• Eliminate wrinkles
• Maintain uniform roll hardness
• Increase production efficiency
• Reduce material waste
