FORFARANDE OCH ANORDNING FOR TILLVERKNING AV FIBRER AV ETT DRAGBART MATERIAL MED HJELP AV GASSTRALAR

摘要

The process consists in generating neighbouring gas jets (b, c, d, e, etc.) adjacent to a convex guiding surface (14), in diverting the jets and the streams which they induce by flow and adherence along the guiding surface and in bringing laces of ductile substance (s) into the streams induced by the jets in zones situated between the latter on the convex surface. In a second stage each jet enters a main gas stream (B) forming a zone of interaction and entraining the partially drawn fibre therein; the latter is then subjected to additional drawing in the interaction zone. The process is employed especially for making fibres from glass.
