Abstract
A wire tensioning system for a wire-shaped working electrode of a spark erosion machine and a procedure for the tensioning of the working electrode. The working electrode at least nearly circumferentially encompasses a braking roller in a wire entry zone and/or a tensioning roller in a wire withdrawal zone. A nozzle is assigned to the braking and/or the tensioning roller such that the nozzle exerts a tensile force on the working electrode to tension the wire.
