Rotating Machines

Double Twist Bunchers

Sampsistemi supplies a complete range of double-twist bunchers to strand copper, aluminium and relevant alloy wires and lay up insulated conductors.
Sampsistemi bunching machines guarantee best product quality in high performance lines.
Our double-twist bunching machines are designed with a view to produce less stressed strands at increasingly higher speeds, i.e. to produce more efficiently and with higher quality.

Advantages at a glance:

  • Compact design;
  • Low energy consumption thanks to high performance motors and bows;
  • Large diameter ceramic rotor pulleys for maximum strand quality;
  • Accurate control of take-up pull and of the main machine functions;
  • Limited number of brush collectors;
  • Sampsistemi tube-type closed bows available (better resistivity and lower consumption).
Standard double-twist bunching machines BM 800, 630, 560, 355
The Sampsistemi double twist bunching machines are easy-to-maintain, high-performance and compact machines with low consumption rates. All machines are equipped with PLC control. Sampsistemi bunching machines are completed by a specific range of motorised static and dynamic pay-offs, as well as equalizers and compacting devices.
