Abstract

A process for producing different types of windings, especially a flyer winding or a composite winding, in the formation of a spool on a core sleeve of a spindle in a draft-twisting machine or frame in which, instead of displacing the ring rail over the full height of the spool to be formed, the full height is subdivided into zones and the ring rail is reciprocated in each of these zones only through a fraction of the total structure of the ring rail. During the winding in each zone, the spindle speed is held approximately constant and the spindle speed is changed only upon a transition from one zone to another.
