ABSTRACT:
In a high resolution electroerosion printer, a print head comprises a print head body of plastic or glass in which are embedded closely spaced glass tubes. The glass tubes provide low friction passageways for fine wire electrodes which extend through the glass tubes protruding beyond the print head body to be in uninterrupted flexible contact with the metal layer of a record medium. A pair of feed rolls frictionally engage the individual wires such that when the feed rolls are operated they can adjust the position of the wires to compensate for wear of the ends thereof in contact with the metal layer.
