The raw material is fed from the “coil” and the coated wire for winding is cut into “short” pieces, typically 100 to 800 mm long, to produce PINS (so-called i-pins).

These i-pins are then bent into half loops and inserted into the perforated stator plates.

To create a closed winding from this, the half loops must be soldered or welded together.

The ends of the pins are stripped of paint for optimum welding.

Ideally, this should already be done – in-line – on the continuous wire, so that after the cut in the middle of the stripping point, two stripped wire ends are produced.

This paint stripping can be done with mechanical methods or – much more reproducible and process reliable – with the cleanLASER.

Laser stripping must be carried out on all sides of the passing wire.

This means that the laser beam acts from four sides on the mostly rectangular wire cross-section.


The wireLINE optic is ideally suited for this purpose: a single laser beam source is sufficient to deflect the laser beam via a mirror optic and guide it to all four sides.

A very cost-effective method.


  • In Line processing “on the fly” without stopping the wire
  • The laser works in a long working range (approx. 300 mm working length) and can therefore also continuously process “long” pins without loss of efficiency
  • Compact design
  • Central suction
  • Low hardware costs compared to the 4-laser and 4-scanner solution
  • Optional camera-based result control (up to 4 pages)
  • Downstream camera-based in-line result control (up to 4 pages)
