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 ).
