Abstract

A process for producing tapered windings of glass threads consists, downstream from a drawing device of glass filaments joined into a thread, in making the thread pass to the end of the arm of a dancing roller, then winding it on a support attached by one of its ends to a rotationally driven spindle. The thread is distributed on said support with the help of a thread guide reciprocated in parallel to the axis of said support, so as to obtain a winding tapered over at least part of its height.
