<p>In an engraver of an electrical engraving machine for engraving pressure cylinders, the engraver comprises a rotating system which oscillates around small angles. The engraver further comprises a drive system for the rotating system and of an engraving element that is arranged at the rotating system. The engraving element is used to grave cup-shapes in the pressure cylinder by carrying out a lifting movement directed at the pressure cylinder. The clearance angle of the engraver is arranged in a tilt in the direction of the engraving of the cup-shapes in relation to a line of reference which extends vertically to the generated surface of the pressure cylinder. The clearance angle is thus enlarged. Especially buckled cup-shapes can be engraved in the correct tone value using the tilted arrangement of the engraving element.</p> |
