Abstract
Apparatus and cathode for and method of electro-erosive cutting. The cathode is in the form of a wire, especially a round wire. The wire travels over at least two wire guides. A wire-shaping assembly cross-sectionally shapes the round wire just before it starts to cut. A wire-rotating assembly rotates the wire around the latter's longitudinal axis.
