KL, the wire is driven between the two endless belts so that the wire is conveyed between the two endless belts at the exit of the processing area contained between the two electrodes; Wire loading devices whose direction is different from the direction of movement in the processing area are known from the prior art. The relatively large tensions exerted on the wire during its passage through the processing zone force the wire against one of the endless belts, causing rapid wear of the endless belt at the point where the wire enters between the two endless belts.
