Wire Wrapping Machines for Polyimide Tape application

These WTM cable taping machines are designed specifically for the application of polyimide composite tapes on flat and round wires, and its subsequent sintering process.

It is a complex wire taping line, typically with horizontal design, whose layout normally include:

  • Cable pay-off and take-up unit, with standard wire guide or traversing movement, in order to maintain the wire in straight direction without any deviation from its axis;
  • Wire straightening unit with steel rollers and clearing device with brushes, for ensuring the best cable preparation;
  • One or more taping units, with taping heads suitable for big cross wound spools or heavy pads, where WTM dynamic dancer maintains the tape tension constant and stable, guaranteeing a perturbation-free process that is highly appreciated in case of flat wires with a high width/thickness ratio;
  • Pulling units (capstan, one or two caterpillars or combined caterpillar/capstan system), for controlling precisely the linear speed and the wire tension;
  • Fast pre-heating process with high frequency induction heater and following infrared or molten salt bath sintering ovens;
  • Cooling system, with recirculated cold water and air wipers for drying the cable;
  • Compacting units, that allow the complete adhesion of polyimide layers on the conductor;
  • In-line quality control by means of laser gauges, spark tester and WTM Visio System with camera, offering the possibility of product certification and reporting;
  • Paper feeder installed on the take-up unit, suitable for the automatic deposition of a complete turn of paper interlay on the reel during wire winding.

The technical characteristics can be customized according to the specific production requirements of the Customer.
