ABSTRACT In a high-resolution electroerosion print head, the relatively fine electrodes are guided in thin glass tubes, the glass tubes being embedded in the body of the print head or the like. Feed rolls are provided for advancing the electrodes, such feed rolls being paired and each pair including a first, hard roll provided with grooves for guiding the elec- trodes, and as second roll of a relatively softer material. The hard material can be an acrylonitrile-butadiene-styrene-copolymer, and softer material, a polyurethane.
