Abstract: A process and device for the mechanical formation of aerosols are disclosed, whereby the formation of a downwardly flowing liquid film is effected on the slanted surface of a downwardly widening mouthpiece of an air supply line, which mouthpiece points downwards and the breakup of the film at an annular edge of the mouthpiece by an airstream which escapes under slight excess pressure from the interior of the at least approximately cone-shaped hollow space inside the mouthpiece, whereby the film is atomized in the form of an essentially vertically downwardly directed spray cone. A limiting body may be inserted in the mouthpiece to direct the airstream essentially entirely toward the interrupting edge of the mouthpiece.
