This is because any deformation forces arising during the separation process are dissipated by the measures described into the two residual strips S ', S "and thus do not lead to a deformation of the workpieces W to be produced.
  • Another advantage of the procedure described is that it is now possible to dissolve even filigree workpieces W in a single separation process from the strip of material S.
