Abstract

An S-Z twisting machine including a twisting disc operated reversibly at the speed n.sub.1 and a tubular accumulator driven with the lower speed n.sub.2. The elements to be twisted which are applied to the tubular accumulator via an aperture guide disc, are preferably conducted through a further aperture guide disc which is rigidly connected to the tubular accumulator near its center to insure that the loops before and behind the further guide disc are equal per unit length of the tubular accumulator.
