IMPROVEMENT IN THE PROCESS FOR THE MANUFACTURE OF FIBERS FROM AN ATTENUABLE MATERIAL AND APPARATUS FOR THE MANUFACTURE OF FIBRES FROM AN ATTENUABLE MATERIAL BY SAID PROCESS

摘要

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.
