Cable-Laid (Twisted)

The twist direction is indicated by the capital letters “S” and “Z”. When the rope is held vertically, the twist spires in the consecutive rope parts are in the same diagonal direction as indicated with the letter “S” (left hand) or “Z” (right hand). The most common final twist for cabled ropes is “Z”.

The opposite twists result in a “balanced” rope. Varying the number of twists results in a more soft- or hard-laid rope - according to the customer's preference. Without extra specifications, the rope is always produced as “medium” lay. The lay-length is then between 2,8 and 3,5 times the diameter.
Lay length - 3 strand

Composition of a right hand twisted rope:
    Single yarn: bundle of filaments twisted “Z” (right)
  • Cabled yarn: composed of “S”-twisted yarns subsequently twisted together in the “Z” (right) direction
  • Strand: assembly of yarns twisted “S” (left)
  • Rope: assembly of strands “Z”-twisted together - for specific use cabled rope also exists in “S” lay
To avoid kinking it is recommended to uncoil “Z” twisted rope
by pulling out the inner end of the coil counterclockwise.
