A rewinder for rewinding a web into one or more rolls on separate cores, includes at least one rewinding mandrel having a distal end. The rewinder also has a supply device for supplying the web to the rewinding mandrel, and a drive device. The drive device can (a) rotate the rewinding mandrel in order to wind at least a portion of the web onto the rewinding mandrel, and (b) axially retract the mandrel to unload the portion of the web wound on the mandrel. Also included is a holder for holding the one or more rolls. The rewinder also has a lifter for (a) raising the holder to support the portion of the web wound on the mandrel, and (b) lowering the holder. This rewinding mandrel is rotated in order to wind at least a portion of the web onto the rewinding mandrel. The holder is then raised to support the portion of the web wound on the mandrel. Next, the mandrel is axially retracted to unload the portion of the web wound on the mandrel, before lowering the holder.
