The process consists in generating at least one pair of gas jets (a - a) with kinetic energies per unit volume and dimensions which are substantially equal, whose axes are situated practically in the same plane, the two jets converging to form a combined flow after their impact and in conveying the ductile substance (S) into a zone of gases induced by one of the two jets, which zone is situated outside the angle included between these jets. In a second stage the combined flow enters a main gas stream (10) to form a zone of interaction into which the partially drawn fibre is introduced in order to be subjected to additional drawing therein. The process is employed especially for making fibres from glass. <IMAGE> |
