The Daven Differential Shaft allows for the simultaneous rewinding or unwinding of multiple rolls on the same shaft.

Suitable for a full range for slitting and converting production operations. Its universal design is available for any core width and diameter.

Different core widths can be simultaneously wound on the same shaft. Amount of core slippage is a function of the air pressure applied with preset regulator.

Manufactured to your specifications to suit your equipment, including cantilevered or custom designs.
