Preforming Process in Wire Rope Making

Wire rope is a product made by combining numbers of strands together. As these strands are laid over central core by spinning process, there is a tendency of these strands to open up or unlay. To avoid unlaying, strands are given a pre-helix (permanent deformation) which we call it as a preforming. As name suggest this process of preforming is carried just before the actual formation of the rope.
