THIN ROLLED STOCK REELER Russian patent published in 2012 - IPC B21C47/04 

FIELD: process engineering.

SUBSTANCE: proposed device comprises drive articulated with band reeling mandrel with band start locking slot made at mandrel center. Roll with accurate OD and ID is produced due to use of disk-like mandrel with annular groove of inner and outer diameters exceeding required diameters of the roll after its removal from mandrel by amount of elastic deformation. Proposed device is furnished with thrust, drive to displace mandrel along the axis against the stop and band tensioner. Aforesaid thrust is provided with a slot to feed band into mandrel slot while tensioner is made up of immobile curved slot where through band is fed.
