Abstract In a reeling installation for winding metal strips, a drivable and spreadable reeling mandrel (2) is provided, upon which an exchangeable lining (5) made of elastomer material is arranged. A reeling mandrel lining of this type treats the strip to be wound or unwound gently and compensates the differences between the internal diameter of the coil (4) and the external diameter of the reeling mandrel (2). In order to create absolute protection for the strip starts of the coil in addition to these advantages, the elastomer material of the reeling mandrel lining (5) is made soft in the outer region as far as the outer surface of the lining. In the inner region as far as the inner surface of the lin- ing on the other hand the elastomer material is made hard in order to ensure the necessary rigidity and dimen- sional stability of the lining. Consequently a gentle embedding of the strip start into the soft outer layer occurs, whereby marks in the convolution regions of the coil located above the strip start are prevented.
