Abstract
Abstract For SZ stranding, the stranding elements which remain united in the stranding or twisted unit are led in a stretched twisted condition to a twisting device which twists the twisted unit in sections, each of a multiple of stranding strokes. The twisting device is positioned closer to the takeup point than to the payout point of the twisted unit. A longitudinal section of the twisted unit has a minimum length equal to the distance between the takeup point and the twisting device and a maximum length equal to three times the distance between the twisting device and the payout point.
