Abstract

The present invention relates to a process for producing a flow of airborne fibres, characterized by the following stages: a) a continuous length (2) of a thread bundle of fibre material is fed from a stock (1) of fibre material through a roll press (4), which rotates at a rate of feed and with the thread bundle held fast in the nip between its rollers (11, 12), b) on emerging from the roll press (4), individual fibres are broken off from the thread bundle by means of a tearer (5), c) the individual fibres broken off by the tearer are carried away from the tearer by means of an air flow.
