Buncher

A machine that forms individual strands or cables into a desired geometrical formation. They can be single-twist (also referred to as cablers) or double-twist bunchers (DTB). The DTBs were once used nearly exclusively for non-critical twisted or bunched wire products (such as steel cord, welding wire and grounding cables), but have evolved to where they have replaced single-twist bunchers and more traditional stranding methods for demanding products, such as LAN, Cat. 5, Cat. 5e and Cat. 6 cables, building wire, appliance wire and machine tool wire. The DTBs are able to run much faster yet with limited elongation loss.
