Each curved plate (5) is provided with alternating projections (50, 54) and slots (52, 56) making the curved plates capable of fitting into each other. By utilizing the air shaft, a web material can be wound en the air shaft directly without the need of mounting a roll on an outer surface of the air shaft.
