Abstract
To be able to correct irregularities in the length of lay, which result from the reversal of the twisting device in SZ twisting devices with very large storage capacity, a post-twisting device is arranged after the SZ twisting device, the post-twisting device including a retwisting disc with an equalization section in the back thereof. The length of the equalization section is at least five times the resulting length of lay; the speed of rotation of the post-twisting device is equal to the difference between two successive speed steps of the SZ twisting device and direction of rotation of the post-twisting device is changed in the same rhythm as the rotary motion of the SZ twisting device.
