Expandable Sleeves

Hutchinson expandable sleeves are designed for coil winding and unwinding operations involving steel strips and sheets. Installed on uncoiler and recoiler mandrels, they ensure strip stability while protecting metal surfaces.
Compatible with all mandrel diameters and expansion ranges, they help standardize coil diameters. They replace metal spacers, standardize coil diameters, and contribute to improved process quality and reliability.

Main Benefits

Standardization of coil diameters
Optimal preservation of metal strip surface quality
Excellent grip during winding and unwinding
Minimized marking on the first coil wraps
Resistance to harsh industrial environments
