Abstract

The invention concerns a method and a coiler mandrel for coiling metal strip (110), wherein the coiler mandrel (100) comprises a mandrel body (120), a plurality of radially expandable segments (115) arranged around the mandrel body (120), and a plurality of hydraulic cylinders (116) by which the segments (115) 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 (116) of the plurality of cylinders be individually controlled.
