A rewinder mandrel system for winding paper into rolls on a mandrel (10, 20, 30, 40, 50, 60) is provided. The system includes a turret assembly having at least one mandrel rotatably affixed thereto. The rewinder mandrel system can also include a gas circulation system that can aid in the positioning, loading, and removing of paper or paper cores located on the mandrel. In particular, the gas circulation system can contain one or more gas flow control devices configured to provide positive pressure and a suction force. In one embodiment, a gas flow control device rotatably affixed to the turret interacts with a second stationary gas flow control device to provide air circulation to the mandrels.
