ABSTRACT:
The invention relates to an improvement of a manufacturing process for making a filament directly from a molten material. The process consists of the ejection of a liquid filament which solidifies in air by making a rotating disc touch the surface of a liquid. The improvement consists in the stabilization of the meniscus which appears upon the wheel near the surface of the liquid and thereby fixing the point where the filament leaves the wheel in order to obtain a constant cross section of the filament. The meniscus is stabilized by the interposition of a body: a rod or a convex piece of a material which does not react with the melt.
