Double Twist cabstan single bow

Double twist bunching machine single bow, fully motorized with cabstan

The double twist bunching machine is made to bunch copper wires.

The main characteristics of the Altec double twist are:

  • Energy save thanks to the single bow made in carbon fiber and aerodynamic profile and high performance motor
  • Bunching pitch set by HMI
  • Traversing pitch and bobbin limits set by HMI
  • Bow with ceramic dies

The single bow with aerodynamic profile, made in carbon fiber, and the perfect balancing of the rotors reduce the installed power of the main motor saving the electrical power consumption and halving the axial pull on the rotor’s bearings.

The stranding pitch is set from the HMI and the electrical axis between the main motor and the double haul-off takes it constant during the production of the bunched wires. A dancer with loading cell control the tension on the take-up.

The traversing pitch and the limits of the bobbin are set also from the HMI and can be modified during the machine running.
