ABSTRACT:
For the layer-wise SZ-stranding of elements to be stranded about a core strand, the elements to be stranded are first temporarily cabled onto the core strand with a long lay and alternating direction of lay, subsequently roped down from the core strand by means of a first cabling disc and fed, parallel to the core strand, to a second, oscillating cabling disc by means of which the final stranding is accomplished. The two cabling discs advantageously form the end faces of a twisting cage which revolves with alternating direction of rotation, with the distance of a first twisting closer, into which the core strand and the elements to be cabled enter, from the first cabling disc and the distance of the first cabling disc from the second cabling disc larger than the distance of the twist reversal points in the finished stranded material.
