A mandrel wheel for producing packages is illustrated and described, including: a mandrel wheel shaft having a central axis, a plurality of mandrels attached to the mandrel wheel shaft, an inflow for a coolant and an outflow for the coolant. The mandrels form at least one mandrel group, the mandrels of which are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft. Each mandrel has a hollow space for the coolant, which is connected to an inlet and to an outlet separate from it. At least one distribution element is provided, which connects all inlets of a mandrel group to the inflow and which connects all outlets of the same mandrel group to the outflow, so that the mandrels can be cooled more effectively.
