The invention is concerned with a continuous cable core stranding technique, wherein thick cable cores are concentrated into a bundle or bunch at a first stranding point, and hauled off therefrom by one or more gripping jaw or tong haul-off assemblies, which rotate about the bundle axis to S-Z strand the cores and which retain the stranded material in a torsion free state over a predetermined distance. From these retaining means, the material is advanced to a second stranding point. According to the invention, the interval (l) between the end of the retaining means and the second stranding point is an even-number multiple of (i.e. at least twice) the storage length, the latter being the distance lsp from the beginning to the end of the one or more haul-off assemblies mentioned above. This measure makes it possible to minimise "waviness" in the cable core bundle or bunch. The cores concentrated into a bundle or bunch at the first stranding point may, immediately after leaving the latter, be wrapped with one or more retaining helices, whereby deviations of the stranded elements from their desired positions in the stranded assembly may be minimised, even with stranding elements of large cross-section. <IMAGE> |
