In order to make an optimum air-mass flow available to a particular measuring step, the flow cross-section of the orifices is adjusted as a function of a test program. A blade which extends in the shape of an arc in the ball head portion when seen in the axial direction and which extends at the radial coordinate of the largest outer diameter in the axial cutting portion is provided on each cutting wedge outer edge facing the flute in the right-hand rotational direction. The outline of the inner panel 4 between the outer peripheral seamed portions when the inner panel is deployed in a plane is formed into a shape following a straight line connecting the outer peripheral seamed portions. The invention also comprises a nail and cuticle conditioning composition and a semi-permanent film forming composition containing the fluorinated oil. The temperature of the melt in the second crucible is initially higher than the growing temperature of the first melt and causes the growing end of the boule to melt.
