Fully Automatic Winding Machines

Our fully automatic winding machines allow the operator to leave the machine during the production of the coils. The operator is free to prepare other coils or to run other machines while the production continues. Only at the beginning and at the end of the winding process or when taps must be made the operator is required at the machine. We can provide fully automatic winding machines for instrument transformer coils, distribution transformer coils or other high-voltage coils.

Sensors which are integrated in the machine will detect errors during the winding process and stop the machine. The operator will get optical or acoustical signals when his presence at the machine is required.

The advantages of a fully automatic machine are the high productivity and the constant high winding quality of the coils which is independend of the machine operator. On the other hand a fully automatic machine will require high quality winding materials to allow a trouble-free operation.

Depending on the types of coils to be wound the following optional devices can be supplied:

  • feeding devices for layer insulation (full layer width) with cutting
  • feeding devices for end-fill strips with cutting
  • hot-melt glue devices to stick the insulation or end-fill strips on the coil
  • cutting devices to cut the insulation to the required width with optional rewinder to wind the insulation rest for further usage
  • cutting devices to separate several coils which are wound with a single sheet of insulation
  • electronically controlled or mechanical wire brakes
  • flatteners to shape round wire to flat wire

These optional accessories allow the adaption of the machines to a wide range of customer requirements.
