The Bartell high-speed tubular stranders are constructed with durability and efficiency in mind to meet the most demanding production requirements. The tubular stranders are ideal for many industries and products such as copper, steel, stainless steel, gold, silver, jewelry, medical, automotive, aerospace, musical instrument wire, magnet wire, and fiber optic, push-pull cables, and many other specialty products and operate with 100% backtwist movement. With a state of the art design manufacturers can produce a quality product at higher speeds than ever before. The new ergonomically designed guarding package allows for easy string-up and maintenance. With the optional sound proofing, the noise level of the machine can be dramatically reduced. Available in configurations for the production of large wire conductors, round wire armoring or fine wire the Bartell tubular stranders set the standard for high-speed concentric stranding.

  • Loading/unloading system
  • Wire tension monitoring
  • Wire straightening assemblies
  • Pre-forming heads
  • Sound proofing packages
  • Magnetic particle brake for each bobbin.
  • An additional bobbin assembly located at the rear of the machine to provide the capability for an additional wire.
  • Air operated clutch that links the capstan to a belt driven take-up.
  • An integral core payoff assembly provides the means of placing a larger reel of core product in the first cradle position, thus providing a means to present the core product with zero twist induced. The other bobbin wires are routed around the core product position, before entering the die.
  • Many versions of take-up assemblies available
