The cake (7), fitted with the rough pressing (71) of the stem parison (61) is situated on the ring (8) where by the action of its own gravity, it streams off till the rough pressing (71) fits into the cavity (41) of the bottom mould (4). There the rough pressing (71) is fastened by the underpressure and the air is blasted into the flask (6) and, in the same time, the bottom mould (4) is forced downwards. When the orifice (42) of the cavity (41) comes on the level of the surface (51) of the bottom opening of the glass-blowing mould (5), the glass-blowing mould (5) is closed and the air is blasted into the flask (6) until it obtains the shape of the inner wall (52) of the glass-blowing mould (5).
