Wedge Uncoiler

Hayes Wedge Uncoilers are a 6-tonne capacity single capstan uncoiler operating using a hydraulic wedge system that provides a sturdy and reliable grip on coils.

A 4-leaf mandrel mounted to the top of the Uncoiler body via two large heavy duty captive bearings expands and retracts to hold the coil via a hydraulically operated wedge and drawbar system powered by a dedicated onboard hydraulic powerpack mounted inside the Uncoiler body.

The Uncoiler is controlled by a standalone operator console that also houses all necessary electrical equipment and can be operated in manual or automatic mode in tandem with Rollforming machinery.
