Abstract
The invention concerns a method and a coiler mandrel for coiling metal strip (), wherein the coiler mandrel () comprises a mandrel body (), a plurality of radially expandable segments () arranged around the mandrel body (), and a plurality of hydraulic cylinders () by which the segments () can be moved in the radial direction. To be able to coil the metal strip with a circular coil eye even when the friction varies in the individual cylinders, the invention proposes that each cylinder () of the plurality of cylinders be individually controlled.
