Abstract

A process and an apparatus is proposed for the production of very fine filaments in the form of endless filaments or of very fine melt-blown fibres, for which the melt or spinning holes of the spinneret are in each case surrounded individually by a preferably annular blow nozzle. In this way the emerging filaments are in each case surrounded by concentric flows of gas which help to draw the filaments. <IMAGE>
